Default Re: Inductor or resistor

Basically Coil are inductor because they have inductance value.

Your power supply design is very weird, it usually use with real coil not low powered inductance such as the picture, it blown because it can't hold the heat from current passing through. that's typical cheap power supply, they use wrong parts (cheapest) for easily blown out and you will decide to buy another )

if you unsure, you can bypass it with jumper wire, because line filter (EMI filter) should be after line input. or you can try the 1.5mH, it doesn't do much.

Most cheapest power supply like this use the design without line filter or X cap or Ycap, because they tends to fail and blow up if they buy from cheapest distributor.
