AVX VCAS Series TransGuard® Automotive MLVs

Multilayer Varistors for Automotive Applications



AVX offers the VCAS Series TransGuard® Automotive Multi-Layer Varistors ( MLVs ) as auto-grade zinc oxide (ZnO) based MLV s. The VCAS Series TransGuard® MLV s from AVX have the advantage of offering bi-directional overvoltage protection as well as EMI/RFI attenuation in a single SMT package. The high current and high energy handling capability of the VCAS Series MLV s make these devices well suited for protection against automotive-related transients . Available with 16v, 18v, 26v, 30v, 38v, 42v, 48v, 56v, and 85v DC ratings and 0402 to 1210 size options.
