Product List
NTC stands for Negative Temperature Coefficient, and the NTC thermistor is a resistor with a negative temperature coefficient. This temperature sensor uses the resistance properties of a ceramic/metal composite material to measure temperature - the resistance decreases with increasing temperature.
Therefore, NTC thermistors are mainly used as resistive temperature sensors and current-limiting devices. In other words, the diode NTC thermistor/glass encapsulated NTC thermistor/CIG NTC thermistor is great for ICLs (inrush current limiters) to protect circuits of electrical and electronic devices against inrush currents easily and effectively.
Why Choose The NTC Temperature Sensor?
Just like the PTC resistor, the NTC resistor is also suitable for temperature measurement - the resistance value varies according to the ambient temperature. In order to avoid falsifying the results, self-heating should be limited as much as possible. However, self-heating during current flow can be used to limit inrush currents.Because the NTC resistor is cold when the electrical device is switched on, only a small amount of current flows at first. After a period of operation, the thermistor heats up, the resistance drops, and more current flows. In this way, the electrical device achieves its full performance with a certain time delay.
An NTC resistor is even less able to conduct current at low temperatures. If the ambient temperature rises, the resistance of the so-called warm conductor drops significantly. The special behavior of semiconductor elements can be used primarily for temperature measurement, to limit inrush currents, or to delay various control processes.

Construction Of Diode NTC Thermistors
Diode NTC thermistors are constructed using a semiconductor material, typically silicon, germanium, or gallium arsenide, that has been doped with impurities to create a specific type of electrical behavior. The semiconductor material is then formed into a diode shape, which consists of a p-n junction between a p-type and an n-type semiconductor. The diode NTC thermistor is encapsulated in a glass or plastic package that protects it from mechanical stress and environmental factors. The package also provides electrical contacts for connecting the thermistor to a circuit.Applications Of Diode NTC Thermistors
Diode NTC thermistors are used in a wide range of applications that require temperature sensing or control, including:Overcurrent protection in power supplies and motor control circuits.
Temperature compensation in electronic circuits, such as voltage regulators and oscillators.
