Tantalum Surface Mount Capacitors – Low ESR
Tantalum Stack MnO2 (TSM)
Overview
The KEMET Tantalum Stacks MnO2 (TSM) is designed
to provide the highest capacitance/voltage ratings in
surfaceꢀmountꢀconfiguration.ꢀKEMET'sꢀT493ꢀCOTSꢀmilitary/
aerospace capacitors are utilized in stacks of 2, 3, 4,and 6
components to achieve a broad range of capacitance and
voltage ratings. The T493 COTS offers component level
Weibull grading options, surge current testing options and
standard, low, and ultra-low ESR options. All component
level lots of this product are conditioned with MIL-PRF-55365
