F About Us Of The Glass Encapsulated NTC Thermistors MF59
Ampfort Electronics also designs and manufactures high precision NTC thermistors, probes, and cable assemblies. A thermistor is a type of resistor whose resistance is dependent on temperature. Resistors are always made of ceramic or metal composites. Ntc Thermistor is actually the Temperature Sensor that uses the resistance properties of these resistors to measure the temperature. We offer a full range of NTC thermistors and sensors including micro size, excellent stability, high accuracy and etc.
