Overview
The KEMET T494 Series is a lower ESR version of the popular
T491 Series, designed speci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. 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 481-1. This system provides perfect
compatibility with all tape-fed placement units.

Low ESR MnO2 Tantalum Surface Mount Capacitors – T494 Industrial Grade Low ESR MnO2 Series
Other part number options:
Where the 10th character equal to K (10% tolerance) is also available in M (20% tolerance).
Where the 10th character equal to M (20% tolerance) is only available in M (20% tolerance).
Standard with tin terminations (14th character = T). Tin/lead terminations is also available (14th character = H)
Also available on large (13 inch) reels. Add 7280 to the end of the part number.
Higher voltage ratings and tighter tolerance product including ESR may be substituted within the same size at KEMET's option. Voltage substitutions will be marked
with the higher voltage rating. Substitutions can include better than series.

Low ESR MnO2 Tantalum Surface Mount Capacitors – T494 Industrial Grade Low ESR MnO2 Series
Other part number options:
Where the 10th character equal to K (10% tolerance) is also available in M (20% tolerance).
Where the 10th character equal to M (20% tolerance) is only available in M (20% tolerance).
Standard with tin terminations (14th character = T). Tin/lead terminations is also available (14th character = H)
Also available on large (13 inch) reels. Add 7280 to the end of the part number.
Higher voltage ratings and tighter tolerance product including ESR may be substituted within the same size at KEMET's option. Voltage substitutions will be marked
with the higher voltage rating. Substitutions can include better than series.

Low ESR MnO2 Tantalum Surface Mount Capacitors – T494 Industrial Grade Low ESR MnO2 Series
Other part number options:
Where the 10th character equal to K (10% tolerance) is also available in M (20% tolerance).
Where the 10th character equal to M (20% tolerance) is only available in M (20% tolerance).
Standard with tin terminations (14th character = T). Tin/lead terminations is also available (14th character = H)
Also available on large (13 inch) reels. Add 7280 to the end of the part number.
Higher voltage ratings and tighter tolerance product including ESR may be substituted within the same size at KEMET's option. Voltage substitutions will be marked
with the higher voltage rating. Substitutions can include better than series.

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 identi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 reow solder
processes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reow solder processes.
Density Level C: For high component desity product applications. Before adapting the minimum land pattern variations the user should perform quali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.

Soldering Process
KEMET’s families of surface mount tantalum capacitors are
compatible with wave (single or dual), convection, IR or vapor
phase reow techniques. Preheating of these components
is recommended to avoid extreme thermal stress. KEMET's
recommended prole conditions for convection and IR reow reect
the prole conditions of the IPC/J-STD-020D standard for moisture
sensitivety testing. The devices can safely withstand a maximum of
three reow passes at these conditions.
Note that although the X/7343-43 case size can withstand wave
soldering, the tall prole (4.3mm maximum) dictates care in wave
process development.

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 40 degrees C, and maximum storage humidity not
exceed 60% relative humidity. In addition, temperature 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.
