Polymer capacitors address mission critical applications

With its robust anode quality, benign failure mode, mechanically robust assembly and epoxy housing, the T583 series is suited 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. T583 devices provide low and stable ESR and enhanced capacitance retention at higher frequencies and low temperatures. This results in what the company claims to be the highest total capacitance and most economical solution for high power applications.

KEMET’s T583 series meets 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. T583 capacitors are designed to operate over a temperature range of -55 to 105°C. A detail specification was released by ESCC (3012/005) and the T583 series complies with its requirements.
