  • 10-May-2013 03:23 EDT

The AVL series of radial-leaded automotive varistors from Stackpole Electronics, Inc., through its alliance with KEKO Varicon, is designed to protect automotive-level electrical systems from transient voltage events. The UL 1449-certified AVL series is intended specifically to protect 12-, 24-, and 42-V automotive electrical systems. It includes both multilayer and single-layer components, defined by WLD capability. Multilayer devices are intended for WLD applications that require up to 50 J, and single-layer discs are for WLD applications that require above 50 J. According to the company, the RoHS-compliant series features a one-time load dump energy handling of up to 100 J and can handle up to 2000 A peak. The AEC-Q200 qualified Grade 1 series offers a 14- to 40-V ac operating voltage range and a 16- to 56-V dc operating voltage (higher operating voltages are available upon request).
