NTC thermistors, or Negative Temperature Coefficient thermistors, are temperature sensors that measure temperature changes through resistance changes. The WM103J1B is a NTC thermistor made by Ohmite and specifically designed for sensing temperatures accurately between 90°C (194°F) and 125°C (257°F). It is a self-heating, 0.1" radial mount thermistor with an operating voltage of 250V and an 100K ohm resistance at 25°C.

The WM103J1B thermistor utilizes the self-heating principle to detect the temperature fluctuation. The mechanism involves sensors being heated by a small current that is passed through their coils. The heating of the thermistor is what reads the temperature change and determines resistance as the thermistor gets hotter or cooler. The resistance then change linearly proportional to the temperature change, with the resistance lowering as the temperature rises and increasing as the temperature drops.

The uses of the WM103J1B thermistor are mostly found in the fields of testing and calibration, temperature control, and industrial automation. The thermistor is often used in any component or system that requires precise temperature sensing and accurate temperature sensitive readings. They are especially desirable for longer measuring durations, as thermistors are able to respond quickly to sudden temperature changes and remain stable in continuously fluctuating temperature environments.

The WM103J1B thermistor is also able to remain stable in continuously changing temperature environments thanks to its low profile design, which gives it the advantage of lower temperature drift than conventional thermistors. Because of its low profile design, this thermistor also features higher resistance accuracy and faster temperature response time. Additionally, the WM103J1B also features power dissipation ratings that enable it to be used in higher temperature applications, up to 125°C ( 257°F).

In conclusion, the WM103J1B thermistor is a reliable temperature sensor that is capable of providing accurate and stable temperature readings over a wide range of temperatures, from 90°C (194°F) up to 125°C (257°F). It is used in various applications that require precise and sensitive temperature sensing, such as test and calibration, temperature control, and industrial automation. Its low profile design also provides it with greater accuracy and temperature stability, allowing it to be used in more demanding applications.
