Ceramic PTC thermistors have been used for various applications since Murata first commercialized them back in the 1950’s. Since then, thermistors have been used in ceramic heaters, motor starters and degaussing relays with an excellent service record. As PTC thermistor technology evolved, new products for overheat sensing and overcurrent protection have been developed. These thermistor-based circuit protection products offer advanced safety solutions for batteries, computers, cell phones, automotives and any other cutting-edge products.
