Tantalum Surface Mount Capacitors – Automotive
T491 Industrial Grade MnO
2
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.
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–D. 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.
