Question Dell AIO Coil Fail

[Oggyuk]

Any ideas where I can get a Coil/Inducer 1R5F??? or 1R5H TMP K1401. Overheated and burnt out.

 

[AllanGH]

Do a lookup over at Mouser Electronics.

 

[Oggyuk]

Still struggling to find a equivalent as I'm not sure of the value. is it 0.15uH, 1.5uH or 15uH.

 

[AllanGH]

I'm assuming that you're working with surface mount, or smallish through-hole, components, so 1.5µH would be what you're shooting for.

Do you happen to have a photo of the board area where the burned inductor is installed?

[AllanGH]

You're going to have to ferret-out the cause for that cooking itself. If something transitory happened, that would be less of a concern than some more consistent cause. In either case, you may have damaged silicon in there too....most likely in series with the inductor.

 

[Oggyuk]

I think the cause was both fans were completely clogged, absolutely solid.
Hoping to replace the inductor and hope for the best.
I just cant find anywhere to order a new inductor from.

If you:
Desolder it from the PC board
Clear out the ferrite without breaking it
Get an accurate count of the windings
Have the same gauge magnet wire on hand
You can wind your own, and solder it in place.
