KYOCERA AVX VT series high temerature automotive resistors

High temperature 150°C/175°C multi-layer varistors are designed for underhood and other high temperature automotive or industrial applications. Parts are AEC-Q200 qualified. They offer bi-directional overvoltage protection as well as EMI/RFI attenuation in a single SMT package.

This allows designers the ability to combine the circuit protection and EMI/ RFI attenuation function into a single highly reliable device.

Products have been tested, qualified, and specified to 150/175ºC and they do not require any derating over specified operating temperature range.

The 48V system varistors, included in the VT series, are designed and tested for use in motor vehicles with a 48- volt power supply. This series of parts is test against VDA-320.
