Zinc Oxide Varistor For Automotive Electronics Resistor
Automotive Grade ZnO Varistor is a voltage sensitive ceramic protective component designed specifically for automotive electronic environments, in compliance with the AEC-Q200 standard. Its core function is to clamp transient overvoltage and absorb surge energy.


Features:
1. High reliability certification: Passed AEC-Q200 stress testing standard
2. Wide temperature range: -55 ℃~+125 ℃ (some can reach up to 150 ℃)
3. Environmental impact resistance: Passed thousands of temperature cycles from -40 ℃ to 125 ℃ and high temperature and high humidity tests at 85 ℃/85% RH
4. High energy/high wave surge: Strong resistance to load dump, EFT, ESD capability
5. Lead free, RoHS compliant: compatible with automotive environmental requirements
