Webb9 juni 2024 · Does a SCR ie Thyristor work for Inrush current protection in a circuit ? Yes it does. To limit inrush you need two things 1) something to limit current (higher resistance). 2) something to bypass the limiter (lower resistance). Now an NTC thermistor does satisfy these needs as its resistance starts off high and then decreases. http://novelfull.to/search-gilmru/LCD-Display-diymore-LCR-T-Multifunction-ESR-Meter-Transistor-Tester-Diode-Triode-Capacitance-SCR-375978/
