KYOCERA AVX High-Temperature Automotive Varistors
KYOCERA AVX High-Temperature Automotive Varistors offer bidirectional protection and are AEC-Q200 qualified. The VTA AEC-Q200-qualified multilayer varistors allow designers to combine the circuit protection and EMI/RFI attenuation function into a single highly reliable device. The VTA series is tested, qualified, and specified for temperatures up to +175°C with no derating, and offers varistors with FLEXITERM® technology that provides up to 5mm of flexure without internal cracking. The VGAH series features a +150°C maximum temperature and is available in larger sizes than the VT series. The VGAH varistors are glass-encapsulated, providing enhanced resistance against harsh environments.
VGAS multilayer varistors are glass-encapsulated TransGuard® zinc oxide (ZnO) based ceramic semiconductor devices with bi-directional voltage-current, non-linear characteristics. These varistors feature high current capability and high energy absorption, making them ideal for protection against automotive-related transients. VCAS varistors are available with either TransGuard or FLEXITERM technology. TransGuard VCAS varistors offer bi-directional overvoltage protection and EMI/RFI attention in a single SMT package as well as high current and high energy handling capability. VCAS varistors with FLEXITERM have FLEXITERM technology that provides up to 5mm of flexure without internal cracking, making them suitable for depanelization and variable temperature applications. KYOCERA AVX High-Temperature Automotive Varistors are ideal for under-the-hood, downhole drilling, and high-temperature applications.
