The KEMET Tantalum Stacks MnO2 (TSM) Series is designed to provide the highest capacitance/voltage ratings in surface mount configuration. KEMET’s T493 COTS Military/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 series offers component level Weibull grading options, surge current testing options and standard, low, and ultra-low ESR options. All component level lots of this series are conditioned with MIL-PRF-55365 Group A testing. Stacking configurations offer this high reliability product with custom capacitance/voltage solutions and very low ESR options.
