KEMET Introduces Extensive New Line of Polymer COTS Capacitors

T543 Series Provides Designers with Tools to Customize Capacitance Solutions for Maximizing Application Performance

Greenville, South Carolina (August 20, 2012) /PRNewswire/ — KEMET Corporation (NYSE: KEM), a leading manufacturer of tantalum, ceramic, aluminum, film, paper and electrolytic capacitors, today introduced its extensive new line of polymer Commercial Off-the-Shelf (COTS) capacitors. The T543 Series offers over 300 discrete part numbers not including termination, ESR and surge current options. This extensive offering provides designers with the tools necessary to customize their capacitance solutions and maximize application performance.

“The features of the T543 Series will allow our customers to use up to 90% fewer capacitors, providing the lowest cost solution for power management,” said Dr. Philip Lessner, KEMET Senior Vice President, Chief Technology Officer and Chief Scientist. “Low ESR characteristics and outstanding power dissipation 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,” stated Ed Jones, KEMET Specialty Tantalum Product Manager. “This 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.
