AVX automotive series varistors are an ideal choice for circuit protection in automotive applications thanks to a wide range of highly reliable, AEC-Q200 qualified components; including low capacitance varistors for high-speed data lines/RF circuits, components with enhanced EMI filtering, as well as high energy, high temperature or harsh environment varistors.

The AVX TransGuard® Multilayer Varistors with unique high-energy multilayer construction represent state-of-the-art overvoltage circuit protection. Monolithic multilayer construction provides protection from voltage transients caused by ESD (e.g. IEC 61000-4-2), lightning, inductive switching, automotive related transients such as load dump (ISO 7637-2-5), jump start and other automotive transients (e.g. ISO 7637 Pulse 1-3, AEC-Q200-002, ISO 10605, ISO 16750-2, CI-220, CI-260).
