Polymer Electrolytic Capacitors Suit Space Applications


KEMET Corporation has unleashed new polymer electrolytic capacitors for space applications. The new T583 Space Grade series is designed for mission critical, high capacitance and high ripple current applications. Examples include communications, industrial, space, defense and aerospace applications.

Featuring robust anode quality, benign failure mode, mechanically robust assembly and epoxy housing, the capacitors are ideal for use in point of load (PoL) applications such as buck-boost converters, filtering, hold-up capacitors, and other high ripple or high in-rush current applications.

Key features include extremely low and stable ESR, and enhanced capacitance retention at higher frequencies and low temperatures. This results in the highest total capacitance and most economical solution for high power applications.

The devices meet the requirements of the European Space Components Coordination (ESCC) Generic Specification No. 3012 for Capacitors, Leadless Surface Mounted, Tantalum, Solid Electrolyte, which ensures these products are suitable for high reliability applications.


Operating temperature range is specified from -55 to +105 degrees Celsius. A detail specification was released by ESCC (3012/005) and the T583 series complies with its requirements.
