Hi All,
I need to replace one component (it’s most likely PTC thermistor) which is blown out. I do not have schematic diagram, nor I can read it from the existing part (it is blown to pieces).
The Client is NOT willing to replace the whole board, as it’s beyond his price range.

Could you help me with either the schematic or the part value.

Brand: Power First
Device: Lieo Controller DKN
Board: PF-905
Part designator: RH1

Can you get a better closeup of the part? It doesn't look blow up in the photo? Oh, I see that photo online. It's not your photo.

Have you looked thru this?
