Z5U Dielectric
General Specifications
Z5U formulations are “general-purpose” ceramics which are
meant primarily for use in limited temperature applications
where small size and cost are important. Z5U show wide
variations in capacitance under influence of environmental
and electrical operating conditions.
Despite their capacitance instability, Z5U formulations
are very popular because of their small size, low ESL, low
ESR and excellent frequency response. These features are
particularly important for decoupling application where only a
minimum capacitance value is required.

General Description
Formulations – Multilayer ceramic capacitors are available
in both Class 1 and Class 2 formulations. Temperature
compensating formulation are Class 1 and temperature
stable and general application formulations are classified
as Class 2.
Class 1 – Class 1 capacitors or temperature compensating
capacitors are usually made from mixtures of titanates
where barium titanate is normally not a major part of the
mix. They have predictable temperature coefficients and
in general, do not have an aging characteristic. Thus they
are the most stable capacitor available. The most popular
Class 1 multilayer ceramic capacitors are C0G (NP0)
temperature compensating capacitors (negative-positive
0 ppm/°C).
Class 2 – EIA Class 2 capacitors typically are based on the
chemistry of barium titanate and provide a wide range of
capacitance values and temperature stability. The most
commonly used Class 2 dielectrics are X7R and Y5V. The
X7R provides intermediate capacitance values which vary
only ±15% over the temperature range of -55°C to 125°C. It
finds applications where stability over a wide temperature
range is required.
The Y5V provides the highest capacitance values and is
used in applications where limited temperature changes are
expected. The capacitance value for Y5V can vary from
22% to -82% over the -30°C to 85°C temperature range.
The Z5U dielectric is between X7R and Y5V in both stability
and capacitance range.
All Class 2 capacitors vary in capacitance value under the
influence of temperature, operating voltage (both AC and
DC), and frequency. For additional information on perfor-
mance changes with operating conditions, consult AVX’s
software, SpiCap.
Basic Construction – A multilayer ceramic (MLC) capaci-
tor is a monolithic block of ceramic containing two sets of
offset, interleaved planar electrodes that extend to two
opposite surfaces of the ceramic dielectric. This simple
structure requires a considerable amount of sophistication,
both in material and manufacture, to produce it in the quality
and quantities needed in today’s electronic equipment.

General Description
Effects of Voltage – Variations in voltage have little effect
on Class 1 dielectric but does affect the capacitance and
dissipation factor of Class 2 dielectrics. The application of
DC voltage reduces both the capacitance and dissipation
factor while the application of an AC voltage within a
reasonable range tends to increase both capacitance and
dissipation factor readings. If a high enough AC voltage is
applied, eventually it will reduce capacitance just as a DC
voltage will. Figure 2 shows the effects of AC voltage.
Capacitor specifications specify the AC voltage at which to
measure (normally 0.5 or 1 VAC) and application of the
wrong voltage can cause spurious readings. Figure 3 gives
the voltage coefficient of dissipation factor for various AC
voltages at 1 kilohertz. Applications of different frequencies
will affect the percentage changes versus voltages.
The effect of the application of DC voltage is shown in
Figure 4. The voltage coefficient is more pronounced for
higher K dielectrics. These figures are shown for room tem-
perature conditions. The combination characteristic known
as voltage temperature limits which shows the effects of
rated voltage over the operating temperature range is
shown in Figure 5 for the military BX characteristic.

AVX X7R T.C.
Effects of Time – Class 2 ceramic capacitors change
capacitance and dissipation factor with time as well as tem-
perature, voltage and frequency. This change with time is
known as aging. Aging is caused by a gradual re-alignment
of the crystalline structure of the ceramic and produces an
exponential loss in capacitance and decrease in dissipation
factor versus time. A typical curve of aging rate for semi-
stable ceramics is shown in Figure 6.
If a Class 2 ceramic capacitor that has been sitting on the
shelf for a period of time, is heated above its curie point,
(125°C for 4 hours or 150°C for 12hour will suffice) the part
will de-age and return to its initial capacitance and dissi-
pation factor readings. Because the capacitance changes
rapidly, immediately after de-aging, the basic capacitance
measurements are normally referred to a time period some-
time after the de-aging process. Various manufacturers use
different time bases but the most popular one is one day
or twenty-four hours after “last heat.” Change in the aging
curve can be caused by the application of voltage and
other stresses. The possible changes in capacitance due to
de-aging by heating the unit explain why capacitance
changes are allowed after test, such as temperature cycling,
moisture resistance, etc., in MIL specs. The application of
high voltages such as dielectric withstanding voltages also

tends to de-age capacitors and is why re-reading of capac-

tions after dielectric strength tests have been performed.
Effects of Frequency – Frequency affects capacitance
and impedance characteristics of capacitors. This effect is
much more pronounced in high dielectric constant ceramic
formulation that is low K formulations. AVX’s SpiCap soft-
ware generates impedance, ESR, series inductance, series
resonant frequency and capacitance all as functions of fre-
quency, temperature and DC bias for standard chip sizes
and styles. It is available free from AVX.
Effects of Mechanical Stress – High “K” dielectric
ceramic capacitors exhibit some low level piezoelectric
reactions under mechanical stress. As a general statement,
the piezoelectric output is higher, the higher the dielectric
constant of the ceramic. It is desirable to investigate this
effect before using high “K” dielectrics as coupling capaci-
tors in extremely low level applications.
Reliability – Historically ceramic capacitors have been one
of the most reliable types of capacitors in use today.
The approximate formula for the reliability of a ceramic
capacitor is:
Lo=VtXTtY
LtVoTo
where
Lo= operating life Tt= test temperature and
Lt= test life To= operating temperature
Vt= test voltage in °C
Vo= operating voltage X,Y = see text
Historically for ceramic capacitors exponent X has been
considered as 3. The exponent Y for temperature effects
typically tends to run about 8.
A capacitor is a component which is capable of storing
electrical energy. It consists of two conductive plates (elec-
trodes) separated by insulating material which is called the
dielectric. A typical formula for determining capacitance is:
C = .224 KA
t
C= capacitance (picofarads)
K= dielectric constant (Vacuum = 1)
A= area in square inches
t= separation between the plates in inches
(thickness of dielectric)
.224 = conversion constant
(.0884 for metric system in cm)
Capacitance – The standard unit of capacitance is the
farad. A capacitor has a capacitance of 1 farad when 1
coulomb charges it to 1 volt. One farad is a very large unit
and most capacitors have values in the micro (10-6), nano
(10-9) or pico (10-12) farad level.
Dielectric Constant – In the formula for capacitance given
above the dielectric constant of a vacuum is arbitrarily cho-
sen as the number 1. Dielectric constants of other materials
are then compared to the dielectric constant of a vacuum.
Dielectric Thickness – Capacitance is indirectly propor-
tional to the separation between electrodes. Lower voltage
requirements mean thinner dielectrics and greater capaci-
tance per volume.
Area – Capacitance is directly proportional to the area of
the electrodes. Since the other variables in the equation are
usually set by the performance desired, area is the easiest
parameter to modify to obtain a specific capacitance within
a material group.

General Description
Energy Stored – The energy which can be stored in a
capacitor is given by the formula:
E= 12CV2
E= energy in joules (watts-sec)
V= applied voltage
C= capacitance in farads
Potential Change – A capacitor is a reactive component
which reacts against a change in potential across it. This is
shown by the equation for the linear charge of a capacitor:
Iideal = C dV
dt
where
I= Current
C= Capacitance
dV/dt = Slope of voltage transition across capacitor
Thus an infinite current would be required to instantly
change the potential across a capacitor. The amount of
current a capacitor can “sink” is determined by the above
equation.
Equivalent Circuit – A capacitor, as a practical device,
exhibits not only capacitance but also resistance and induc-
tance. A simplified schematic for the equivalent circuit is:
C= Capacitance L = Inductance
Rs= Series Resistance Rp= Parallel Resistance
Reactance – Since the insulation resistance (Rp) is normally
very high, the total impedance of a capacitor is:
Z = R2
S+ (XC - XL)2
where
Z= Total Impedance
Rs= Series Resistance
XC= Capacitive Reactance = 1
2πfC
XL= Inductive Reactance = 2 πfL
The variation of a capacitor’s impedance with frequency
determines its effectiveness in many applications.
Phase Angle – Power Factor and Dissipation Factor are
often confused since they are both measures of the loss in a
capacitor under AC application and are often almost identi-
cal in value. In a “perfect” capacitor the current in the
capacitor will lead the voltage by 90°.
In practice the current leads the voltage by some other
phase angle due to the series resistance RS. The comple-
ment of this angle is called the loss angle and:
Power Factor (P.F.) = Cos for Sine
Dissipation Factor (D.F.) = tan
for small values of the tan and sine are essentially equal
which has led to the common interchangeability of the two
terms in the industry.
Equivalent Series Resistance – The term E.S.R. or
Equivalent Series Resistance combines all losses both
series and parallel in a capacitor at a given frequency so
that the equivalent circuit is reduced to a simple R-C series
connection.
Dissipation Factor – The DF/PF of a capacitor tells what
percent of the apparent power input will turn to heat in the
capacitor.
Dissipation Factor =E.S.R. = (2 πfC) (E.S.R.)
XC
The watts loss are:
Watts loss = (2 πfCV2) (D.F.)
Very low values of dissipation factor are expressed as their
reciprocal for convenience. These are called the “Q” or
Quality factor of capacitors.
Parasitic Inductance – The parasitic inductance of capac-
itors is becoming more and more important in the decou-
pling of today’s high speed digital systems. The relationship
between the inductance and the ripple voltage induced on
the DC voltage line can be seen from the simple inductance
equation:

The seen in current microprocessors can be as high as
0.3 A/ns, and up to 10A/ns. At 0.3 A/ns, 100pH of parasitic
inductance can cause a voltage spike of 30mV. While this
does not sound very drastic, with the Vcc for microproces-
sors decreasing at the current rate, this can be a fairly large
percentage.
Another important, often overlooked, reason for knowing
the parasitic inductance is the calculation of the resonant
frequency. This can be important for high frequency, by-
pass capacitors, as the resonant point will give the most
signal attenuation. The resonant frequency is calculated
from the simple equation:
fres = 1
2LC
Insulation Resistance – Insulation Resistance is the resis-
tance measured across the terminals of a capacitor and
consists principally of the parallel resistance RPshown in
the equivalent circuit. As capacitance values and hence the
area of dielectric increases, the I.R. decreases and hence
the product (C x IR or RC) is often specified in ohm farads
or more commonly megohm-microfarads. Leakage current
is determined by dividing the rated voltage by IR (Ohm’s
Law).
Dielectric Strength – Dielectric Strength is an expression
of the ability of a material to withstand an electrical stress.
Although dielectric strength is ordinarily expressed in volts, it
is actually dependent on the thickness of the dielectric and
thus is also more generically a function of volts/mil.
Dielectric Absorption – A capacitor does not discharge
instantaneously upon application of a short circuit, but
drains gradually after the capacitance proper has been dis-
charged. It is common practice to measure the dielectric
absorption by determining the “reappearing voltage” which
appears across a capacitor at some point in time after it has
been fully discharged under short circuit conditions.
Corona – Corona is the ionization of air or other vapors
which causes them to conduct current. It is especially
prevalent in high voltage units but can occur with low voltages
as well where high voltage gradients occur. The energy
discharged degrades the performance of the capacitor and
can in time cause catastrophic failures.

Component Pad Design
Component pads should be designed to achieve good sol-
der filets and minimize component movement during reflow
soldering. Pad designs are given below for the most com-
mon sizes of multilayer ceramic capacitors for both wave
and reflow soldering. The basis of these designs is:
Pad width equal to component width. It is permissible to
decrease this to as low as 85% of component width but it
is not advisable to go below this.
• Pad overlap 0.5mm beneath component.
Pad extension 0.5mm beyond components for reflow and
1.0mm for wave soldering.

REFLOW SOLDERING

WAVE SOLDERING
Component Spacing
For wave soldering components, must be spaced sufficiently
far apart to avoid bridging or shadowing (inability of solder
to penetrate properly into small spaces). This is less impor-
tant for reflow soldering but sufficient space must be
allowed to enable rework should it be required.
Preheat & Soldering
The rate of preheat should not exceed 4°C/second to
prevent thermal shock. A better maximum figure is about
2°C/second.
For capacitors size 1206 and below, with a maximum
thickness of 1.25mm, it is generally permissible to allow a
temperature differential from preheat to soldering of 150°C.
In all other cases this differential should not exceed 100°C.
For further specific application or process advice, please
consult AVX.
Cleaning
Care should be taken to ensure that the capacitors are
thoroughly cleaned of flux residues especially the space
beneath the capacitor. Such residues may otherwise
become conductive and effectively offer a low resistance
bypass to the capacitor.
Ultrasonic cleaning is permissible, the recommended
conditions being 8 Watts/litre at 20-45 kHz, with a process
cycle of 2 minutes vapor rinse, 2 minutes immersion in the
ultrasonic solvent bath and finally 2 minutes vapor rinse.

they will withstand the time/temperature profiles used in both
wave and reflow soldering methods.
Handling
Chip multilayer ceramic capacitors should be handled with
care to avoid damage or contamination from perspiration
and skin oils. The use of tweezers or vacuum pick ups
is strongly recommended for individual components. Bulk
handling should ensure that abrasion and mechanical shock
are minimized. Taped and reeled components provides the
ideal medium for direct presentation to the placement
machine. Any mechanical shock should be minimized during
handling chip multilayer ceramic capacitors.
Preheat
It is important to avoid the possibility of thermal shock during
soldering and carefully controlled preheat is therefore
required. The rate of preheat should not exceed 4°C/second
and a target figure 2°C/second is recommended. Although
an 80°C to 120°C temperature differential is preferred,
recent developments allow a temperature differential
between the component surface and the soldering temper-
ature of 150°C (Maximum) for capacitors of 1210 size and
below with a maximum thickness of 1.25mm. The user is
cautioned that the risk of thermal shock increases as chip
size or temperature differential increases.
Soldering
Mildly activated rosin fluxes are preferred. The minimum
amount of solder to give a good joint should be used.
Excessive solder can lead to damage from the stresses
caused by the difference in coefficients of expansion
between solder, chip and substrate. AVX terminations are
suitable for all wave and reflow soldering systems. If hand
soldering cannot be avoided, the preferred technique is the
utilization of hot air soldering tools.
Cooling
Natural cooling in air is preferred, as this minimizes stresses
within the soldered joint. When forced air cooling is used,
cooling rate should not exceed 4°C/second. Quenching
is not recommended but if used, maximum temperature
differentials should be observed according to the preheat
conditions above.
Cleaning
Flux residues may be hygroscopic or acidic and must be
removed. AVX MLC capacitors are acceptable for use with
all of the solvents described in the specifications MIL-STD-
202 and EIA-RS-198. Alcohol based solvents are acceptable
and properly controlled water cleaning systems are also
acceptable. Many other solvents have been proven successful,
and most solvents that are acceptable to other components
on circuit assemblies are equally acceptable for use with
ceramic capacitors.
