KEMET Corporation is expanding the KEMET Organic Capacitor (KO-CAP) family with the release of 63 volt product extensions for the T521 High Voltage Polymer Series, as well as first-to-market extensions for the T540 and T541 Hi-Rel Polymer Commercial-Off-the-Shelf (COTS) Series and T543 Polymer Tantalum COTS Series.
In addition to use in higher voltage input rails such as 48 volt telecom rails, these 63 volt releases are suitable for 48 volt automotive power supplies currently in development and avionics designers seeking high voltage ratings that meet the transient and overvoltage requirements of MIL-STD-704F for the 28 volt power bus.
Typical markets include telecommunications, transportation, computer, industrial, lighting, alternative energy, and defence and aerospace. These devices complement KEMET’s T520, T493, 497, and T528 Series.
“KEMET’s continued advancements in polymer technology now allow designers working with higher voltage power systems, such as 48 volt telecom rails, to take full advantage of the benefits found in polymer tantalum capacitors,” stated Dr. Philip Lessner, KEMET Senior Vice President, Chief Technology and Marketing Officer. “The 63 volt rating allows designers to use KEMET polymer capacitors on line voltages up to 50 volts,” continued Dr. Lessner.
