Automotive Circuit Protection / Thermistors

Murata Electronics Automotive Circuit Protection and Thermistors include a wide lineup of characteristics for various electronic devices, including smartphones and wearable terminals, and automobile/automotive devices. Heat is generated by applied voltage and current, and the resistance changes along with the temperature. Murata thermistors function as a heating element and thermo-sensitive device and play an active role in various applications, such as temperature sensors, circuit protection, and temperature compensation.
