Applications of NTC thermistors 2

3、 Power circuit protection

NTC thermistors can be used as protective components in power circuits to prevent faults such as circuit overload and short circuits. Under normal working conditions, the resistance value of NTC thermistor is very small and will not affect the circuit. But when the circuit is overloaded or short circuited, the current of the NTC thermistor will increase sharply, causing its temperature to rise and the resistance value to increase, thereby limiting the current and protecting the circuit. diode

4、 Motor protection

NTC thermistor can be used as a temperature sensor in motor protectors to monitor and protect the temperature of the motor. When the temperature of the motor rises to a certain value, the resistance value of the NTC thermistor will sharply increase, causing a decrease in the current in the circuit and thus achieving protection for the motor.

5、 Household appliances

NTC thermistors are widely used in household appliances such as water heaters, ovens, toasters, induction cookers, etc. In water heaters, NTC thermistors are used as temperature sensors to control the temperature of hot water. In ovens and toasters, NTC thermistors are used as temperature sensors to control the internal temperature of the oven and toaster. In induction cookers, NTC thermistors are used as power circuit protection components to prevent faults such as circuit overload and short circuits.diode
