Tantalum Surface Mount Capacitors – Standard Tantalum

T491 Industrial Grade MnO₂ Series

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. 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.

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.

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.
