KEMET Offers High Voltage Large Case Multilayer Ceramic Capacitors for Higher Reliability Applications
August 2, 2011
GREENVILLE, SC – July 29, 2011 – KEMET Corporation (NYSE: KEM), a leading manufacturerof tantalum, ceramic, aluminum, film, paper and electrolytic capacitors, announced its KEMET Power Solutions (KPS) High Voltage (HV) SMSeries capacitors. Designed to meet robust performance standardsrequired in higher reliability industrial applications, the KPS familyof devices utilizes leadframe technology to isolate the multilayerceramic component from the printed circuit board.
KPS technology provides enhanced mechanical and thermal stress performance, said Bill Sloka,Specialty Product Manager. KPS SM Series devices are engineered withrobust chip designs for higher reliability applications.
KPS HV SM Series devices offer up to 10mm of board flex capabilityand exhibit lower ESR, ESL and higher current discharge capability whencompared to other dielectric solutions. Available in both formed L andJ lead configurations, these products offer additional screeningoptions, including Group A and Group B testing/inspection perMIL-PRF-49467.
Typical markets include power supply, LCD fluorescent backlightballast, HID lighting, telecom equipment, industrial and medicalequipment/control, military and downhole exploration. Typicalapplications include switch mode power supplies (input filters,resonators, tank circuits, snubber circuits, output filters), highvoltage coupling and DC blocking, voltage multiplier circuits, DC/DCconverters and coupling capacitors in Cuk converters, noise reduction(piezoelectric/mechanical), circuits with a direct battery or powersource connection, critical and safety relevant circuits without(integrated) current limitation and any application that is subject tohigh levels of board flexure or temperature cycling.
