NTC Thermistors

NTC Thermistors are one of the most common temperature sensors used in electronics and automation. NTC Thermistors are essentially resistors that vary their resistance as the temperature rises and falls. NTC Thermistors are made up of a semiconductor material, usually ceramic, with a negatively charged surface. As the temperature increases the resistance of the NTC Thermistor increases.

JS8741B Application Field

The JS8741B is a thermistor made of ceramics and is used in a wide range applications, including temperature sensing, over current protection devices, surge-withstand current machineries, thermal protection, temperature control of pipelines and computers, and home appliances. It is also widely used in automotive and industrial applications, such as temperature transmitters, as various pipelines and containers. It is also applied in measuring and controlling temperature and pressure in air conditioning system.

JS8741B Working Principle

The thermistor is composed of semiconductive material, typically ceramic. The thermistor’s resistance increases as the temperature increases and decreases as the temperature decreases. The resistance curve associated with the thermistor depends on the material. The JS8741B has a response time of 1.2 seconds. The time to respond to changes in temperature is dependent on the type of thermistor.

The JS8741B is a semiconductor device that operates at low voltages. The device is composed of a ceramic element and four electrodes. It is constructed of two NTC elements which are three times more sensitive to temperature changes than other thermistor-type temperature sensors. The thermistor is designed to monitor temperature changes of -200°C to 200°C and changes of up to 50 mV at 100°C.

The JS8741B measures the temperature when voltage is applied across the terminals. At the same time, current flows through the element and, as the temperature varies, the resistance of the thermistor will change accordingly. As the temperature rises, the thermistor resistance rises, while as the temperature falls the resistance decreases. This change enables precise temperature sensing. The thermistor will provide a reading through a voltage signal which is calculated by the voltage across the two terminals.

Conclusion

The JS8741B NTC Thermistor is an excellent choice for temperature sensing applications, with its accurate and stable temperature response and low power consumption. As a result, it is a popular choice for applications requiring precise temperature sensing. The NTC thermistor is designed to monitor temperature, over current protection, thermal protection, and home appliances.
