Tantalum Surface Mount Capacitors – Low ESR
Tantalum Stack MnO
2
(TSM)
Overview
The KEMET Tantalum Stacks MnO
2
(TSM) 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 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
Group A testing. Stacking configurations offer this high
reliability product with custom capacitance/voltage solutions
and very low ESR options.
Note: Custom stacking solutions are available with other KEMET Tantalum
MnO
2
Surface Mount products. Please contact KEMET Sales for availability.
