Tantalum Surface Mount Capacitors – Standard Tantalum
T491 Series Industrial Grade MnO
2
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. This series is classified as MSL (Moisture
Sensitivity Level) 1 under J STD 020: unlimited floor life
time at ≤ 30°C/85% RH. The T491 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), N =
Non-Magnetic 100% Tin (Sn), M = Non-Magnetic (SnPb). 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.
