Data Sheet PRF Series PRF Series PTC Thermistor PRF Series Applications Features Automotive Faster response (LED Lamp/Navigation/Motor/Electrical Component) Wide Sensing Temperature LED Bulb Compact Design to save Board space Mobile phone Low profile High Reliability Note PC, Tablet PC RoHS Compliant and Halogen Free Battery Safety Standard Power Supply (UL : E137188 VDE, TUV etc.) Motor and Motor Controller Overview Exploiting the PTC characteristic (a sharp increase in resistance above a certain temperature), the PRF series chip PTC thermistors are used for overheat sensing in FETs, power ICs, and other heat generating areas. Use of the sharp change in electrical resistance translates into outstanding noise resistance. Sharp changes in resistance make it possible to accurately detect overheating in multiple areas using a very simple circuit connecting PTC thermistors in series. This allows the customer to reduce the number of IC ports, thereby downsizing equipment. Attention: This datasheet is downloaded from the website of Murata Manufacturing Co., Ltd.
