Temperature Sensors - NTC Thermistors

NTC thermistors are temperature sensors composed of a sintered semiconductor material and are used in a wide range of temperature sensing and temperature control applications. The ND03J00681K NTC thermistor is one such temperature sensor that has a wide temperature sensing range and can be used in varying applications. This section will discuss the application field of ND03J00681K and its working principle.

Applications of ND03J00681K

The ND03J00681K is mainly used in temperature measurement and control in consumer electronics, such as TV sets, DVD players, microwave ovens, air conditioners and other home appliances; automotives, such as car headlights, automotive GM modules and control systems; and industrial and medical equipment, such as water heaters, musical instruments, and various medical appliances. This thermistor is designed to operate in a wide temperature range of -40 to +125℃.

Working Principle of ND03J00681K

NTC thermistors work on the principle of the Inverse Temperature Coefficient (ITC) of electrical resistivity. As the temperatures around the thermistor increase, the electrical resistance of the thermistor decreases. The ND03J00681K follows this principle and utilizes a sintered semiconductor material which changes its resistance in response to varying temperature. This temperature sensing is further calibrated using external electronics to produce results in a format easier to interpret.

When the ND03J00681K thermistor is used in temperature sensing applications, it is usually connected in a circuit that is composed of a voltage source, the thermistor, and a current-measuring device such as an ammeter. When temperature changes, the resistance of the thermistor changes in concert. This change in resistance changes the current flowing through the circuit, which is measured by the ammeter, and serves as an indication of the temperature. If a voltage source is connected to the circuit, the current value is proportional to the voltage, and this proportional can be used to calculate the temperature.

The ND03J00681K can also be used in temperature control applications, such as controlling air conditioners, water heaters or ovens. In such applications, the resistance or voltage value is used to compare against the desired temperature setpoint, and the temperature is controlled by adjusting the control voltage or current applied in the circuit by the voltage source.

Conclusion

The ND03J00681K is an NTC thermistor used in temperature sensing and control applications with a wide temperature range of -40 to +125℃. It works on the principle of the Inverse Temperature Coefficient (ITC) of electrical resistivity, whereby the electrical resistance of the thermistor decreases as the temperatures around the thermistor increase. When used in temperature sensing applications, the ND03J00681K is connected in a circuit that is composed of a voltage source, the thermistor, and a current-measuring device such as an ammeter. When temperature changes, the resistance of the thermistor changes in concert with this and this change in resistance is used to calculate the temperature. The ND03J00681K can also be used for temperature control applications, such as controlling air conditioners, water heaters or ovens, where the resistance or voltage value is used to compare against the desired temperature setpoint and the temperature is controlled by adjusting the control voltage or current applied in the circuit by the voltage source.
