 Need help identifying electronic component

Sound like capacitors to me. They are often disc shaped with radial leads (leads extending out the edges) and mounted on boards in a vertical orientation. Capacitors are rated in Farads (like pF, uF, etc). Any letters like that on 'em?

I'm not a EE and don't specify these sorts of parts but here's my best guess, which may well be totally wrong.

circle and NP may be manufacturer

it has a J which usually means Joules which might mean it's an energy device, my guess is a varistor.

The E1 and 06 may be a date code, with 06 the year.

TH-x is probably the series.

Seems there should be more numbers (voltage rating at least)

By resistor symbol do you mean the Greek Omega character?

Ah, the TH is on the PC board and not the fried part? They are very likely thermistors. They are often used in power related devices as inrush current limiters.

A good place to get them is digikey.com. If they are on the side of the circuit where the AC power comes in they are probably 120V and tolerance is probably not critical. Other than that... well, I'm no EE. Good luck.

Just to prove I don't know what I'm talking about... DigiKey doesn't even give voltage ratings for the thermistors.

This is a real SWAG, but try this. Measure the diameter of the fried part, and the distance between the leads. Go to the link below, pick the diameter and lead spacing that is closest to what you have, select bulk packaging, and click the "Apply Filters" button. I'll bet the items that show up all have approximately the same ratings. My guess is you can't go wrong if you pick the parts with the highest Max Amp rating.

But I take no responsibility for any fire that may ensue Smile

Good Luck. Let us know how it turns out, and be sure to record a video when you power it up for the first time Smile
