FAQ
Q: What are the reasons for the safety problems of thermistors in use?
A: Thermistors often have some safety accidents in practical applications. There are two main reasons for such accidents:

(1) The aging of the thermistor itself makes it ineffective. The PTC thermistor is mainly used to block the current. If it loses this function, the sudden burst of current will cause a dangerous accident. Since the resistor is a component, it will age after a long time of use. If you do not pay attention to the inspection, it will cause an accident. Therefore, the thermistor must be checked frequently during use.

(2) The thermistor is destroyed by the ultra-high voltage. In the process of operation, there are often ultra-high voltages. At this time, due to the sudden rise of the voltage, the thermistor is destroyed and becomes invalid. If the current cannot be blocked, a safety accident will occur. Therefore, when using the thermistor, you must pay attention to inspection. It is best to install a fuse with a preventive effect, which can greatly reduce the risk of safety accidents.
