GENERAL INFORMATION

A capacitor is a component which is capable

of storing electrical energy. It consists of two conductive

plates (electrodes) 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 chosen 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 volt-

age requirements mean thinner dielectrics and greater

capacitance 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 capaci-

tance within a material group.

Energy Stored – The energy which can be stored in a

capacitor is given by the formula:

E= 1⁄2CV2

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

inductance. 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

2 πfC

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

identical in value. In a “perfect” capacitor the current in

the capacitor will lead the voltage by 90°.

The Capacitor

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.

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.

CERAMIC CAPACITORS

Multilayer ceramic capacitors are manufactured by mixing

the ceramic powder in an organic binder (slurry) and cast-

ing it by one technique or another into thin layers typically

ranging from about 3 mils in thickness down to 1 mil or

thinner.

Metal electrodes are deposited onto the green ceramic

layers which are then stacked to form a laminated

structure. The metal electrodes are arranged so that their

terminations alternate from one edge of the capacitor to

another. Upon sintering at high temperature the part

becomes a monolithic block which can provide extremely

high capacitance values in small mechanical volumes.

Figure 1 shows a pictorial view of a multilayer ceramic

capacitor.

Multilayer ceramic capacitors are available in a wide range of

characteristics, Electronic Industries Association (EIA) and

the military have established categories to help divide the

basic characteristics into more easily specified classes. The

basic industry specification for ceramic capacitors is EIA

specification RS-198 and as noted in the general section

it specifies temperature compensating capacitors as Class

1 capacitors. These are specified by the military under

specification MIL-C-20. General purpose capacitors with

non-linear temperature coefficients are called Class 2

capacitors by EIA and are specified by the military under

MIL-C-11015 and MIL-C-39014. The new high reliability

military specification, MIL-C-123 covers both Class 1 and

Class 2 dielectrics.

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. Normally the

T.C.s of Class 1 temperature compensating capacitors are

C0G (NP0) (negative-positive 0 ppm/°C). Class 1 extended

temperature compensating capacitors are also manufac-

tured in T.C.s from P100 through N2200.

Class 2 – General purpose ceramic capacitors are called

Class 2 capacitors and have become extremely popular

because of the high capacitance values available in very

small size. Class 2 capacitors are “ferro electric” and vary in

capacitance value under the influence of the environmental

and electrical operating conditions. Class 2 capacitors

are affected by temperature, voltage (both AC and DC),

frequency and time. Temperature effects for Class 2

ceramic capacitors are exhibited as non-linear capacitance

changes with temperature.

+25°C and +85°C and that T.C. becomes more negative at low temperature. Wider tolerances are required on low capacitance values because of the effects of

stray capacitance.

Temperature characteristic is specified by combining range and change

symbols, for example BR or AW. Specification slash sheets indicate the

characteristic applicable to a given style of capacitor.

EXAMPLE – A capacitor is desired with the capacitance value at 25°C

to increase no more than 7.5% or decrease no more than 7.5% from

-30°C to +85°C. EIA Code will be Y5F.

In specifying capacitance change with temperature for

Class 2 materials, EIA expresses the capacitance change

over an operating temperature range by a 3 symbol code.

The first symbol represents the cold temperature end of the

temperature range, the second represents the upper limit

of the operating temperature range and the third symbol

represents the capacitance change allowed over the

operating temperature range. Table 2 provides a detailed

explanation of the EIA system.

Effects of Voltage – Variations in voltage affects only the

capacitance and dissipation factor. 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.

“Q” vs. Frequency

Effects of Frequency – Frequency affects capacitance

and dissipation factor as shown in Figures 6 and 7.

Variation of impedance with frequency is an important con-

sideration for decoupling capacitor applications. Lead

length, lead configuration and body size all affect the

impedance level over more than ceramic formulation varia-

tions. (Figure 8)

Effects of Time – Class 2 ceramic capacitors change

capacitance and dissipation factor with time as well as

temperature, voltage and frequency. This change with time

is known as aging. Aging is caused by a gradual re-align-

ment 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 semistable ceramics is shown in Figure 9 and a

table is given showing the aging rates of various dielectrics.

If a 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 1⁄2hour will suffice) the part will

de-age and return to its initial capacitance and dissipation

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 capacitance after 12 or 24 hours is allowed in

military specifications after dielectric strength tests have

been performed.

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 con-

stant of the ceramic. It is desirable to investigate this effect

before using high “K” dielectrics as coupling capacitors 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 in °C

Vt= test voltage

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.

GENERAL ELECTRICAL AND

ENVIRONMENTAL SPECIFICATIONS

Many AVX ceramic capacitors are purchased in accordance

with Military Specifications, MIL-C-39014, MIL-C-11015,

MIL-C-20, MIL-C-55681, and MIL-C-123 or according to

individual customer specification. When ordered to these

specifications, the parts will meet the requirements set forth

in these documents. The General Electrical and

Environmental Specifications listed below detail test

conditions which are common to the foregoing and to most

ceramic capacitor specifications. If additional information is

needed, AVX Application Engineers are ready to assist you.

Capacitance – Capacitance shall be tested in accordance

with Method 305 of MIL-STD-202.

Class 1 dielectric to 1000 pF measured at 1 MHz, ± 100

KHz, > 1000 pF measured at 1 KHz ± 100 Hz both at 1.0

± 0.2 VAC.

Class 2 dielectrics (except High K) to 100 pF shall be mea-

sured at 1 MHz ± 100 KHz, > 100 pF measured at 1 KHz ±

100 Hz both at 1.0 ± 0.2 VAC.

High K dielectrics measured at 1 KHz ± 100 Hz with less

than 0.5 VAC or less applied.

Dissipation Factor – D.F. shall be measured at the same

frequency and voltage as specified for capacitance.

Dielectric Strength – The dielectric strength shall be mea-

sured in accordance with Method 301 of MIL-STD-202 with

a suitable resistor in series with the power supply to limit

the charging current to 50 ma. max.

Insulation Resistance – Insulation Resistance shall be

measured in accordance with Method 302 of MIL-STD-202

with rated voltage or 200 VDC whichever is less applied.

The current shall be limited to 50 ma. max. and the charg-

ing time shall be 2.0 minutes maximum.

Burn-In – (Where specified.) 100% of the parts shall be

subjected to 5 cycles of Thermal Shock per Method 107

Test Condition A of MIL-STD-202 followed by voltage con-

ditioning at twice rated voltage and maximum rated tem-

perature for 100 hours or as specified. After Burn-In, parts

shall meet all initial requirements.

Barometric Pressure – Capacitors shall be tested in

accordance with Method 105 of MIL-STD-202 Test

Condition D (100,000 ft.) with 100% rated voltage applied

for 5 seconds with current limited to 50 ma. No evidence of

flashover or damage is permitted.

Solderability – Capacitors shall be tested in accordance

with Method 208 of MIL-STD-202 with 95% coverage of

new solder.

Vibration – Capacitors shall be tested in accordance with

Method 208 Test Condition D of MIL-STD-202 with the

bodies rigidly clamped. The specimens shall be tested in 3

mutually perpendicular planes for a total of 8 hours with

125% rated DC voltage applied. No evidence of opens,

intermittents or shorts is permitted.

Shock – Capacitors shall be tested in accordance with

Method 213 Condition 1 (100 Gs) of MIL-STD-202 with the

bodies rigidly clamped. No evidence of opens, intermit-

tents or shorts is permitted.

Thermal Shock and Immersion – Capacitors shall be

tested in accordance with Method 107 Condition A of

MIL-STD-202 with high test temperature (maximum rated

operating temperature) followed by Method 104 of

MIL-STD-202 Test Condition B.

Moisture Resistance – Capacitors shall be tested in

accordance with Method 106 of MIL-STD-202 with rated

voltage or 100 VDC whichever is less applied for the first 10

cycles.

Resistance to Solder Heat – Capacitors shall be tested in

accordance with Method 210 of MIL-STD-202 with immer-

sion to .050 of body. AVX Ceralam capacitors are manu-

factured with solder which melts at a temperature greater

than 450°F.

General Considerations – The application of voltage or

temperature usually causes temporary changes in the

capacitance of Class 2 ceramic capacitors. These changes

are normally in the positive direction and may cause out-of-

tolerance capacitance readings. If a capacitance reading is

made immediately after a dielectric strength or insulation

resistance test and parts are high capacitance, they should

be re-read after a minimum wait of 12 hours.
