Medium Power Multilayer Varistors from AVX Protect Against Automotive Related Transients

MYRTLE BEACH, S.C.--Oct. 2, 20042, 2004--AVX Corporation offers a comprehensive range of multilayer chip varistors (MLV) for transient voltage protection, ESD protection and EMI suppression. AVX recently introduced the VC Series of medium power varistors to protect against automotive related transients. The new medium power varistor series offers both EMC filtering and large energy transient suppression in a single package. These devices are capable of "jump start" and "load dump" conditions, and exhibit little or no degradation to repetitive electrical surges.

The VC Series medium power MLVs provide complete solutions to inductively generated transients (ISO 7637) and are load dump rated to 25j. "The medium power varistors are a natural extension of the AVX communication bus protection series - the LIN, CAN and J1850," explained Ron Demcko, Applications Engineering Manager for AVX. Additionally, these varistors are ideal in suppressing transients in hybrid vehicle applications such as regenerative braking, electric drive and engine start/stop transition circuitry.

"The VC Series is ideal for automotive applications due to its ability to suppress transients over an extremely broad speed and energy content range," continued Demcko.

The VC Series features Pd/Ag terminations and is available in case sizes 1206 to 2220. The MLVs can be specified to different levels of load dump and jump start test requirements and provide a broad EMC response as a result of intentional capacitance built into the varistor. Operating voltages are from 14Vrms to 34Vdc and the operating temperature range is -55(degree)C to +125(degree)C.

Pricing starts at $0.25 each for the VJ13 Series. Lead times are from stock to 10 weeks.
