Standard MnO2 Tantalum Surface Mount Capacitors
T491 Industrial Grade MnO2 Series
Overview
The KEMET T491 Series, designed specifically for today’s highly
automated surface mount processes and equipment, is the
leading choice for surface mount designs. The T491 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.
The T491 standard terminations are 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. The symmetrical terminations offer total
compliancy to provide the thermal and mechanical stress relief
required with today's technology. Lead frame attachments to the
tantalum pellet are made via a microprocessor-controlled welding
operation, and a high temperature silver epoxy adhesive system.
This product meets or exceeds the requirements of EIA standard
535BAAC. The physical outline and dimensions of this series
conform to this global standard. Five low profile case sizes
are available in the T491 Series. The R/2012-12, S/3216-12
and T/3528-12 case sizes have a maximum height of 1.2 mm.
The U/6032-15 size has a maximum height of 1.5 mm, and the
V/7343-20 has a maximum height of 2.0 mm.
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.

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 identified 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 reflow solder
processes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reflow solder processes.
Density Level C: For high component desity product applications. Before adapting the minimum land pattern variations the user should perform qualification
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 reflow techniques. Preheating of these components
Max Ramp Up Rate = 3 C/sec
°
Max Ramp Down Rate = 6 C/sec
°
tL
is recommended to avoid extreme thermal stress. KEMET's
recommended profile conditions for convection and IR reflow reflect
the profile conditions of the IPC/J-STD-020D standard for moisture
sensitivety testing. The devices can safely withstand a maximum of
three reflow passes at these conditions.
Note that although the X/7343-43 case size can withstand wave
soldering, the tall profile (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 fluctuations 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.
