FR104 is a NTC thermistor- a type of thermistor that utilizes a Negative Temperature Coefficient (NTC) to measure and detect changes in temperature. It is designed to be used in high temperature applications and its characteristics make it ideal for temperature sensing and applications such as heating and cooling control, over temperature protection, and automatic temperature control systems. It is made from a high temperature ceramic material with a thick film coating that helps to increase its temperature detection range. Its temperature detection range is from 0? up to 200? and it has a high response time of =5s. It is small in size and its insulated design allows it to withstand higher temperatures. FR104 has a wide range of applications in consumer electronics, industrial equipment, military equipment, automotive, and many other areas.
