Temperature Sensors - NTC Thermistors

NTC thermistors are temperature sensors which respond to changes in temperature by resistance. NTC stands for negative temperature coefficient, which refers to the sensor’s resistance decreasing in conjunction with the rise of temperatures. The term thermistor derives from a combination of ‘thermal’ and ‘resistor’ and thus, as the thermistor is heated its resistance decreases.The ERT-J0ER104JM is a typical NTC thermistor which is popularly used in various applications. This type of thermistor has a resistance at 25°C of 10KΩ and a dissipation constant (P.D) of 1mW/°C. It has a tolerance of 3%, a capacitance of 10PF, and a wide operation temperature range of -40°C to +120°C.

ERT-J0ER104JM Applications

The ERT-J0ER104JM thermistor is ideal for temperature sensors in a number of industries. Industrial applications using the ERT-J0ER104JM include food cooking and cooling processes, air bag wiring systems, and air conditioning systems. Additionally, laboratory equipment and medical equipment may also utilize the ERT-J0ER104JM thermistor.The ERT-J0ER104JM thermistor is favored for use as a temperature sensor due to its inexpensiveness, high accuracy, durability, and compatibility with many types of electronic circuitry.

Working Principle

Fundamentally, the ERT-J0ER104JM thermistor works as a variable resistor which changes in response to rising temperatures due to its negative temperature coefficient. This thermistor works to thwart safe operating temperatures in equipment by altering its electrical resistance strictly in relation to the temperature level to which it is exposed.The ERT-J0ER104JM thermistor works through a semiconductor material within the thermistor which mediates the relationship between temperature and resistance. As the heat rises, a current passes through the thermistor which releases excess energy from the material. The high resistance calculated at lower temperatures is correlated with the semiconductor’s lack of energy. As the energy increases and passes through the thermistor, the resistance is accordingly lowered.

Conclusion

The ERT-J0ER104JM is an NTC thermistor which is most commonly used as a temperature sensor throughout various industries and applications. Through its negative temperature coefficient and the action of semiconductor material within the device, the resistance of the thermistor decreases accordingly with the rise in temperature. The ERT-J0ER104JM thermistor is favored for its broad and versatile applications, as well as its accuracy, durability and affordability.
