KEMET is now on the QPL list for Switch Mode Power Supply (SMPS) Military Stacked Capacitors with MIL-PRF-49470 standard B Level reliability availability. These devices are intended for high reliability SMPS and pulse energy applications. Their low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL) make them ideally suited for input and output filtering of power supply applications as well as snubber applications. The multilayer construction also creates high thermal transfer functions, resulting in very little temperature rise for the generated power giving the capacitors excellent high current handling capability.

The multi-pin arrangement allows the extremely low ESR and ESL of the chip package to be presented to the circuit without any significant increases. This arrangement also allows a very efficient thermal transfer path to exist between the chip package and the PC board, as most of the thermal dissipation for this package will be through the leadframe connection.
