Honeywell's 135-502FAG-J01 is a high-quality, hermetically-sealed glass-encapsulated chip thermistor in an axial lead package. These rugged sensors are designed for applications demanding reliability at a low cost, covering a wide temperature range from -60°C to 300°C. The uniform dimensions facilitate automated assembly. Thermistors are temperature-sensitive resistors; their resistance changes with temperature, making them useful for measurement, control, and compensation in various industrial applications. Self-heating characteristics can be exploited for voltage or power level control.
