Tantalum Surface Mount Capacitors – Automotive
T494 Industrial Grade Low ESR MnO
2
Series
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. 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 481–1. 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.
