Discrete Thermistor 135-104QAD-J01 Thermistor from Honeywell features a rugged DO-35 glass package and has a resistance of up to 100K ohm. These devices can be Negative Temperature Coefficient (NTC) type and Positive Temperature Coefficient (PTC) type. This particular NTC 100K ohm Thermistor has uniform dimensions, 2 % tolerance and an operating temperature range of -60 °C to 300 °C. It is designed economically for applications that demand reliability at a nominal cost. Thermistors are a type of thermally sensitive resistors that are designed to track a significant amount of change in electrical resistance when brought in contact with a corresponding change in body temperature. Honeywell Transducers are used in a variety of applications such as temperature sensors, inrush current limiter, self-resetting over current protectors and self-regulating heating elements.
