KEMET Boosts Protection for Automotive, Medical and Industrial Electronics with New Through-Hole and Surface-Mount Varistors

Seven new series deliver versatile choices including dual-function transient/EMI handling, high humidity resistance, and AEC-Q200 qualified devices

MUNICH, GERMANY--(Marketwired - November 08, 2016) - KEMET Corporation (NYSE: KEM), a leading global supplier of electronic components, introduced seven new series of metal-oxide varistors that complement its existing circuit-protection solutions and can protect critical circuit components from very high-energy discharges. The new devices include dual-function varistor-capacitors that combine transient and EMI protection, and plastic-enclosed varistors for increased reliability in humid environments.

The dual-function devices integrate a capacitor to suppress interference from devices such as DC electric motors and are AEC-Q200 qualified. Compact in size, these devices are ideal for protecting sensitive automotive electronics against electric-motor noise as well as potentially damaging high-energy transients. X7R-capacitor temperature characteristics ensure stable parameters over the specified temperature range.

"The dual-function varistors provide the perfect space-saving solution for new vehicle designs, which feature increasing numbers of electrically-driven mechanisms to boost fuel efficiency as well as convenience and comfort," said Dr. Ralf Deisenhofer, Vice President, Aluminum Electrolytic Technology.

In addition, KEMET has introduced five new surface-mount varistors, including four which are AEC-Q200 qualified. This product line features devices capable of high temperature operation for use in automotive and industrial applications, as well as plastic encapsulations that offer superior humidity resistance for use in medical instruments and equipment such as outdoor mobile-communications infrastructure and professional or consumer white goods.
