How do NTC thermistors suppress surge current? 3

Coordination with other circuit components

In circuit design, NTC thermistors are often used in conjunction with other components to achieve optimal surge current control. For example, when used in conjunction with a relay, an NTC thermistor can limit the current before the relay is pulled in, protecting the relay from damage caused by excessive starting current. In power circuits, NTC thermistors combined with capacitors can effectively suppress surge currents when the power is turned on, while reducing electromagnetic interference. diode

conclusion

NTC thermistor, with its unique temperature sensitive characteristics, effectively suppresses surge currents during circuit startup or power on, protecting the safe and stable operation of the circuit. In modern electronic devices, NTC thermistor is one of the important components for suppressing surge current. Its simple and reliable working principle and economical and practical characteristics have made it widely used in the electronics industry.diode
