Standard MnO Tantalum Surface Mount Capacitors 2 T491 Industrial Grade MnO Series 2 Overview The KEMET T491 Series, designed specifically for todays highly The T491 standard terminations are 100% matte tin and provide automated surface mount processes and equipment, is the excellent wetting characteristics and compatibility with today s leading choice for surface mount designs. The T491 combines surface mount solder systems. Tin/lead (Sn/Pb) terminations KEMETs proven solid tantalum technology, acclaimed and are available upon request for any part number. Gold-plated respected throughout the world, with the latest in materials, terminations are also available for use with conductive epoxy processes and automation, resulting in unsurpassed total attachment processes. The symmetrical terminations offer total performance and value. compliancy to provide the thermal and mechanical stress relief required with today s technology. Lead frame attachments to the This product meets or exceeds the requirements of EIA standard tantalum pellet are made via a microprocessor-controlled welding 535BAAC. The physical outline and dimensions of this series operation, and a high temperature silver epoxy adhesive system. conform to this global standard. Five low profile case sizes are available in the T491 Series. The R/2012-12, S/3216-12 Standard packaging of these devices is tape and reel in and T/3528-12 case sizes have a maximum height of 1.2 mm. accordance with EIA 481-1. This system provides perfect The U/6032-15 size has a maximum height of 1.5 mm, and the compatibility with all tape-fed placement units. V/7343-20 has a maximum height of 2.0 mm. Benefits Applications Meets or Exceeds EIA Standard 535BAAC Typical applications include decoupling and filtering in industrial Taped and Reeled per EIA 481-1 and automotive end applications such as DC/DC converters, Symmetrical, Compliant Terminations portable electronics, telecommunications, and control units.
