Tantalum Surface Mount Capacitors – Automotive Grade

T491 Automotive/Industrial Grade MnO

2

Overview

The KEMET T491, 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 serie conform to this global standard. Five low

profiles case sizes are available. 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. The

symmetrical terminations offer total compliancy to provide

the thermal and mechanical stress relief required with today's

technology. 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.

Benefits

(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.
