Overview

TheKEMETT491Series,designedspecificallyfortoday’shighly

automated surface mount processes and equipment, is the

leading choice for surface mount designs. The T491 combines

KEMET’sprovensolidtantalumtechnology,acclaimedand

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

requirementsofEIAstandard535BAAC.Thisseriesisclassified

as MSL (Moisture Sensitivity Level) 1 under J STD 020: unlimited

floorlifetimeat≤30°C/85%RH.TheT491standardterminations

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.
