Keramiske kondensatorer til krævende applikationer

Kemet introducerer high voltage multilags keramiske kondensatorer til applikationer, hvor der stilles høje pålidelighedskrav (in english).

Kemet has announced its Kemet Power Solutions (KPS) High Voltage (HV) SM Series capacitors. Designed to meet robust performance standards required in higher reliability industrial applications, the KPS family of devices utilises leadframe technology to isolate the multilayer ceramic component from the printed circuit board.

KPS HV SM Series devices offer up to 10mm of board flex capability and exhibit lower ESR, ESL and higher current discharge capability when compared to other dielectric solutions. Available in both formed 'L' and 'J' lead configurations, these products offer additional screening options, including Group A and Group B testing/inspection per MIL-PRF-49467.

Typical markets include power supply, LCD fluorescent backlight ballast, HID lighting, telecom equipment, industrial and medical equipment/control, military and downhole exploration.

Typical applications include switch mode power supplies (input filters, resonators, tank circuits, snubber circuits, output filters), high voltage coupling and DC blocking, voltage multiplier circuits, DC/DC converters and coupling capacitors in Cuk converters, noise reduction (piezoelectric/mechanical), circuits with a direct battery or power source connection, critical and safety relevant circuits without (integrated) current limitation and any application that is subject to high levels of board flexure or temperature cycling.

- KPS technology provides advanced mechanical and thermal stress performance. KPS SM Series devices are engineered with robust chip designs for higher reliability applications, says Bill Sloka, Specialty Product Manager.
