Kemet introduces new line of polymer COTS capacitors

Kemet has introduced a new line of polymer COTS capacitors. The�T543 Series�offers over 300 discrete part numbers not including termination,�ESR,�and surge-current options. This offering provides designers with the tools necessary to customize their capacitance approach and maximise application performance. � "The features of the T543 Series will allow our customers to use up to 90% fewer capacitors, providing the lowest cost approach for power management," said Dr. Philip Lessner,�KEMET�senior VP, CTO, 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 utilises 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 and point-of-load supply and switch-mode power supply in the computer, industrial, defense, and telecommunications markets.� Kemet
