First ever 35 V SMT tantalum chip capacitor

2 April 2008 Passive Components

Kemet has announced the release of what is said to be the first ever 35 V rated surface-mount polymer tantalum chip capacitor.

Since their introduction in the 1990s, polymer tantalum capacitors have become a popular choice for capacitance solutions in the portable consumer electronics market due to their low ESR (equivalent series resistance), high reliability, volumetric efficiency, low-profile design and benign failure mode. To date, these devices have been most commonly used in 14 V (or less) applications and are limited to voltage applications that do not exceed 20 V of continuous duty. These voltage restrictions are driven by limitations in the materials and manufacturing processes that have prevented the industry from achieving higher voltage ratings.

By overcoming these limitations through advancements in materials and manufacturing processes, Kemet has successfully constructed and qualified the first polymer tantalum capacitors suitable for applications of up to 28 V of continuous duty. In addition, these devices have demonstrated surge voltage handling capabilities in excess of 46 V. This increase in voltage rating now provides designers working with higher-voltage applications, such as 24 V and 28 V power input rails, with the option of incorporating polymer tantalum technology into new designs as opposed to incorporating capacitance technologies that do not offer similar performance advantages.

Designated as the T521 Series, the initial offering in this new series includes the popular low-profile V Case Size (7,3 x 4,3 x 1,9 mm) with a capacitance rating of 15 μF and maximum ESR ratings of 100 mΩ.
