Standard MnO₂Tantalum Surface Mount Capacitors

T491 Industrial Grade MnO₂Series

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.

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.

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.

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.
