KEMET Expands Polymer Tantalum Capacitor Portfolio

January 10, 2011 by Jeff Shepard

KEMET Corp. announced the expansion of its Polymer Tantalum portfolio. The KEMET T528 Low ESR/ESL Series, T521 High Voltage Series and T520 Polymer Tantalum Series all feature new product enhancements.

"The KEMET development team has been working to expand our leading edge product offerings for Polymer Tantalum Capacitors," said Jayson Young, KEMET Product Manager for Tantalum and Aluminum Products. "These new introductions offer the benefit of greater capacitance in smaller form factors as well as enhanced electrical performance. Such advancements are critical for the continued evolution of smaller portable electronic devices with higher functionality and lower design cost."

The T528 Low ESR/ESL Polymer Tantalum Series introduces a newly constructed 5mΩ Z case (EIA Case Code 7343-17) design, reducing overall impedance for high switch frequency decoupling applications such as microprocessor decoupling. The reduced impedance of the 5mOhms design allows circuit designers to lower total capacitor piece counts without compromising performance.

Enhancements to the recently released T521 High Voltage Polymer Tantalum Series include 16V and 35V offerings in a number of capacitance values. The T521 Series is a popular solution for circuits that require higher voltages than are typically available in standard polymer tantalum devices and higher performance over traditional tantalum capacitors. With its enhanced voltage derating and low ESR values, the T521 Series delivers increased performance and reliability within a smaller package size compared to currently available capacitor options.

KEMET also introduces six new small case size parts in its standard high-demand T520 Polymer Tantalum Series. Well suited for smart phones, notebook computers and other portable electronics applications, the T520 Series has now expanded its offerings in the small A case sizes (EIA Case Code 3216-18) with voltage ratings of 4 and 6.3V and capacitance ranges from 47 to 100µF.
