Overview
The KEMET T494 Series is a lower ESR version of the popular
T491 Series, designed specifi cally for today’s highly automated
surface mount processes and equipment. The T494 combines
KEMET’s proven solid tantalum technology, acclaimed and
respected throughout the world, with the latest in materials,
processes and automation, resulting in unsurpassed total
performance and value. This product meets or exceeds the
requirements of EIA standard 535BAAC. This series is classifi ed
as MSL (Mositure Sensitivity Level) 1 under J STD 020:
unlimited fl oor life time at ≤30°C / 85% RH. The T494 standard
terminations are available in 100% matte tin and provide excellent
wetting characteristics and compatibility with today's surface
mount solder systems. Tin/lead (Sn/Pb) terminations are available
upon request for any part number. Gold-plated terminations
are also available for use with conductive epoxy attachment
processes. Standard packaging of these devices is tape and
reel in accordance with EIA 481. This system provides perfect
compatibility with all tape-fed placement units.

(1) To complete KEMET part number, insert M for ±20% or K for ±10%. Designates capacitance tolerance.
(2) To complete KEMET part number, insert T = 100% Matte Tin (Sn) Plated, G = Gold Plated, H = Standard Solder coated (SnPb 5% Pb minimum). Designates
termination fi nish.
Refer to Ordering Information for additional detail.
Higher voltage ratings and tighter tolerance product including ESR may be substituted within the same size at KEMET's option. Voltage substitution will be marked
with the higher voltage rating. Substitutions can include better than series.

Ripple Current/Ripple Voltage
Permissible AC ripple voltage and current are related to equivalent
series resistance (ESR) and the power dissipation capabilities of
the device. Permissible AC ripple voltage which may be applied is
limited by two criteria:
1. The positive peak AC voltage plus the DC bias voltage, if any,
must not exceed the DC voltage rating of the capacitor.
2. The negative peak AC voltage in combination with bias
voltage, if any, must not exceed the allowable limits specifi ed for
reverse voltage. See the Reverse Voltage section for allowable
limits.
The maximum power dissipation by case size can be determined
using the table at right. The maximum power dissipation rating
stated in the table must be reduced with increasing environmental
operating temperatures. Refer to the table below for temperature
compensation requirements.

Using the P max of the device, the maximum allowable rms ripple
current or voltage may be determined.
I(max) = √P max/R
E(max) = Z √P max/R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)

Reverse Voltage
Solid tantalum capacitors are polar devices and may be permanently damaged or destroyed if connected with the wrong polarity. The
positive terminal is identifi ed on the capacitor body by a stripe plus in some cases a beveled edge. A small degree of transient reverse
voltage is permissible for short periods per the table. The capacitors should not be operated continuously in reverse mode, even within
these limits.

Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for refl ow solder processes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for refl ow solder processes.
Density Level C: For high component desity product applications. Before adapting the minimum land pattern variations the user should perform qualifi cation
testing based on the conditions outlined in IPC standard 7351 (IPC–7351).
¹ Height of these chips may create problems in wave soldering.
2 Land pattern geometry is too small for silkscreen outline.

Tantalum Surface Mount Capacitors – Low ESR MnO2 Tantalum & Aluminum Surface Mount Capacitors
T494 Industrial Grade Low ESR MnO2 Series
Soldering Process
KEMET’s families of surface mount capacitors are compatible
with wave (single or dual), convection, IR, or vapor phase refl ow
techniques. Preheating of these components is recommended
to avoid extreme thermal stress. KEMET's recommended profi le
conditions for convection and IR refl ow refl ect the profi le conditions
of the IPC/J–STD–020D standard for moisture sensitivity testing.
The devices can safely withstand a maximum of three refl ow
passes at these conditions.
Please note that although the X/7343–43 case size can withstand
wave soldering, the tall profi le (4.3 mm maximum) dictates care in
wave process development.
Hand soldering should be performed with care due to the diffi culty
in process control. If performed, care should be taken to avoid
contact of the soldering iron to the molded case. The iron should
be used to heat the solder pad, applying solder between the pad
and the termination, until refl ow occurs. Once refl ow occurs, the
iron should be removed immediately. “Wiping” the edges of a chip
and heating the top surface is not recommended.
During typical refl ow operations, a slight darkening of the gold-
colored epoxy may be observed. This slight darkening is normal
and not harmful to the product. Marking permanency is not
affected by this change.

Storage
Tantalum chip capacitors should be stored in normal working environments. While the chips themselves are quite robust in other
environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term
storage. In addition, packaging materials will be degraded by high temperature– reels may soften or warp and tape peel force may
increase. KEMET recommends that maximum storage temperature not exceed 40ºC and maximum storage humidity not exceed 60%
relative humidity. Temperature fl uctuations should be minimized to avoid condensation on the parts and atmospheres should be free of
chlorine and sulphur bearing compounds. For optimized solderability chip stock should be used promptly, preferably within three years
of receipt.
