AVX CAN000x CAN BUS Automotive Varistors Expansion AVX CAN000x CAN BUS Automotive Varistors have been expanded with new package sizes, including 0405 2-element and 0612 4-element packages. Learn more AVX CAN0005 CAN BUS Automotive Varistor is a zinc oxide (ZnO) based ceramic semiconductor device with nonlinear voltage-current characteristics (bi-directional). It is similar to back-to-back Zener diodes and an EMC capacitor in parallel. AVX CAN0005 CAN BUS Automotive Varistor has the added advantage of greater current and energy handling capabilities as well as EMI/RFI attenuation. These devices are fabricated by a ceramic sintering process that yields a structure of conductive ZnO grains surrounded by electrically insulating barriers, creating varistor-like behavior. The 0402 is the smallest discreet offering in the CAN BUS Series. View the entire CAN000x CAN BUS Varistor Series
