Tantalum Surface Mount Capacitors – Low ESR
T494 Series Industrial Grade MnO
2
Overview
The KEMET T494 Series is a lower ESR version of the popular
T491 Series, designed specifically 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. This series is classified
as MSL (Moisture Sensitivity Level) 1 under J STD 020:
unlimited floor life time at ≤30°C/85% RH. 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. 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.
