Myrtle Beach, S.C. AVX Corp. has launched a comprehensive range of multi-layer chip varistors (MLV) for transient voltage protection, electrostatic discharge (ESD) protection and electromagnetic interference (EMI) suppression. These new VC series medium power varistors are designed to protect against automotive-related transients.
Offering both EMC filtering and large energy transient suppression in a single package, these MLVs are capable of "jump start" and "load dump" conditions, and exhibit little or no degradation to repetitive electrical surges, said the company. 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. They provide complete solutions to inductively generated transients (ISO 7637) and are load dump rated to 25 joules.
The new MLVs provide operating voltages up to 34 Vdc. The operating temperature range is -55°C to 125°C. The devices feature Pd/Ag terminations and are available in case sizes from 1206 to 2220.
The VC series is suitable for automotive applications because they can suppress transients over an extremely broad speed and energy range, said the company,including hybrid vehicle applications such as regenerative braking, electric drive and engine start/stop transition circuitry.
Pricing starts at $0.25 each for the VJ13 Series. Delivery is from stock to 10 weeks.
