Multi-Layer Varistors

Radial Leaded High Temperature Automotive
150ºC Rated Radial Leaded TransGuard®
GENERAL DESCRIPTION
AVX High Temperature Multi-Layer Varistors are designed for underhood
applications. Products have been tested, qualified, and specified to 150ºC. The
Radial Leaded TransGuard is built for durability in harsh environments. The MLV
advantage is EMI/RFI attenuation in the off state. This allows designers to combine
the circuit protection and EMI/RFI attenuation function into a single highly reliable
device.
