Varistors boost protection for automotive electronics

Series of metal-oxide varistors can protect critical circuit components from very high-energy discharges. 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, devices protect sensitive automotive electronics against electric-motor noise, as well as potentially damaging high-energy transients. http://www.kemet.com
