Tantalum capacitors

16 February 2011 Passive Components

KEMET has announced the expansion of its polymer tantalum portfolio, with the T528 low ESR/ESL series, T521 high-voltage series and T520 polymer tantalum series all featuring new product enhancements.

The T528 low ESR/ESL series introduces a newly-constructed 5 m Z case design, reducing overall impedance for high switch frequency decoupling applications such as microprocessor decoupling. The reduced impedance of the 5 m design allows circuit designers to lower total capacitor piece counts without compromising performance.

Enhancements to the recently-released T521 high-voltage series include 16 V and 35 V 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 small package size.

KEMET also introduced six new small case size parts in its standard high-demand T520 polymer tantalum series. Suitable for smartphones, notebook computers and other portable electronics applications, the T520 series has now expanded its offerings in the small A case sizes with voltage ratings of 4 V and 6,3 V and capacitance ranges from 47 F to 100 F.
