Tantalum polymer capacitors target high capacitance/voltage applications

Kemet, a subsidiary of Yageo Corp., has extended its tantalum polymer capacitor offering with the release of the new Tantalum Stack Polymer (TSP) O case/EIA 7360-43 and the 82 µF/75-V rated voltage extension in the polymer hermetically sealed series.

The TSP series, built on the company’s stacking construction, is designed to provide the highest capacitance/voltage (CV) ratings in surface mount device (SMD) capacitors. These new capacitors target high-voltage power management applications such as buck-boost converters, filtering, hold-up capacitors, and other high ripple current applications that require a small form factor, stable performance, and long operational lifespan.

KEMET’s KO-CAP High Reliability Series T540, T541 and T543 are all available for stack configuration in the TSP series. When stacked, these capacitors allow design engineers to customize for capacitance, voltage, and low equivalent series resistance (ESR), said Kemet.

The TSP series also offers improved derating conditions and larger capacitance to ensure a low failure rate for typical voltage levels, and multiple failure rate options when using Series T540 and T541 devices in a stack configuration, said Kemet. The devices can be used in high power, high frequency, and long-life designs in telecommunications and industrial applications.

In addition, the stacking construction makes the TSP series suited for devices using gallium nitride (GaN) semiconductor technology, including radar applications based on active electronically scanned array (AESA) systems. Other applications include airborne, ground, and naval equipment where GaN radio frequency (RF) semiconductors are part of the design.

The tantalum polymer capacitors series is available through Kemet distributors.
