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.
