Thermistors

.hide-partial { max-height: none; } .show-more { display: none; }

Murata Thermistors use semi-conductive ceramic and electrode printing techniques to form a temperature sensor with negative temperature characteristics, meaning resistant values decrease as ambient temperatures rise. Murata Thermistors are used widely for temperature detection devices, inrush current protection, and temperature compensation in electronics such as mobile devices, secondary batteries, and automobiles. Murata offers a variety of thermistor products to meet the demands of many applications.
