KEMET T491U106020A

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.
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.
Benefits
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.
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.

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 Finish.
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.

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 density 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.

Standard MnO2 Tantalum Surface Mount Capacitors – T491 Industrial Grade MnO2 Series
Soldering Process
Note that although the X/7343-43 case size can withstand wave
soldering, the tall profile (4.3 mm maximum) dictates care in wave
process development.
Hand soldering should be performed with care due to the difficulty
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 reflow occurs. Once reflow occurred, the
iron should be removed immediately. "Wiping" the edges of a chip
and heating the top surface is not recommended.
During typical reflow operations, a slight darkening of the goldcolored epoxy may be observed. This slight darkening is normal
and is not harmful to the product. Marking permanency is not
affected by this change.

KEMET’s families of surface mount capacitors are compatible
with wave (single or dual), convection, IR or vapor phase reflow
techniques. Preheating of these components 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
sensitivity testing. The devices can safely withstand a maximum
of three reflow passes at these conditions.

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. 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.
