Can anyone find this inductor for sale. I managed to rip one off an esc and need to replace it.

Is 10.1x10x3.8mm and I assume it’s a high power one…

Can you solder it back on? You might be able to get the solder to bond to the remnants of the pulled off tab.

Unfortunately it broke off flush and there’s just not enough sticking out to get a good solder joint. What’s surprising is how I can find 68uH inductors in the correct spec, but not 82uH ones…

Maybe search sunlord SWRH1207B-820MT.
Is that the right one?
If thats it, a few places have them. Ebay too.

  1. Try to Dremel around the contact remainders.
  2. It is 82uh. Current correlates with inductor size. Look for this value and this physical size in Digikey smd inductors.
  3. High power is relative, anyway I suppose it is not used directly in the output

This is the wrong size.

But I’m not sure if there would be any issue using a 1040-820 or 1050-820 which technically is the same footprint. I’m not too sure what effect the current rating has on this particular inductor.

I searched on Digikey for inductors of this dimensions and they are approximately 1-1.5A rating.
So then one of the bellow inductor will do as long as it can be soldered into place:

These nice:
SRR1050A-820Y
SRR1050HA-820Y
SRR1240-820M
SRN8040TA-820M

Found on Ali inductor link

I’d try this before the others: https://uk.rs-online.com/web/p/surface-mount-inductors/2713065

Right. It is the best.
Here it is on Digikey:

And more options with current rating 2.5A+:

You’re ignoring the dimensions. You cant have bigger than 11mmx11mm. This means there are really 2 options:

Right! There is not much space.
