New line of polymer COTS capacitors enables designers to customize capacitance solutions for power management

August 21, 2012 // By Paul Buckley
KEMET Corporation has introduced the company’s new line of polymer Commercial Off-the-Shelf (COTS) capacitors. The T543 Series offers more than 300 discrete part numbers not including termination, ESR and surge current options.

The offering provides designers with the tools necessary to customize their capacitance solutions and maximize application performance.

The T543 Series allow designers to use up to 90% fewer capacitors, providing the lowest cost solution for power management.  The devices low ESR characteristics and power dissipation performance results in ripple current that is three times higher than the equivalent MnO2 capacitor.

The T543 Polymer COTS Series utilizes the designs of KEMET’s commercial polymer product with the addition of 24 hours minimum of voltage conditioning and surge current options at +25°C and -55°C/+85°C.  The upscreening, combined with a benign failure mode, assures the design community of long term reliability and worry-free performance.

Typical applications include radar pulse capacitor, point of load supply and switch mode power supply in the computer, industrial, defense and telecommunications markets.


Pricing ranges from $1.00 to $7.00.
