Tantalum Surface Mount Capacitors – Standard Tantalum

T491 Industrial Grade MnO₂

Overview

TheꢀKEMETꢀT491,ꢀdesignedꢀspeciﬁcallyꢀforꢀtoday’sꢀhighlyꢀ

automated surface mount processes and equipment, is

the leading choice for surface mount designs. The T491

combinesꢀKEMET’sꢀprovenꢀsolidꢀtantalumꢀtechnology,ꢀ

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.ꢀTheꢀT491ꢀisꢀclassiﬁedꢀasꢀMSLꢀ(Moistureꢀ

SensitivityꢀLevel)ꢀ1ꢀunderꢀJ-STD-020:ꢀunlimitedꢀﬂoorꢀlifeꢀ

timeꢀatꢀ≤ꢀ30°C/85%ꢀRH.ꢀTheꢀT491ꢀstandardꢀterminationsꢀareꢀ

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.
