| What is the reason for NTC thermistors to suppress surges? |
* Answer
| When the PC is cold-started, it will generate a large inrush current. That is, the AC 220V mains voltage will give the PC a large starting surge current. This large inrush current may burn the power supply and the internal circuit of the host.This is to set up a circuit that suppresses the surge, so that the surge current is small when the PC is turned on. |
