chipped inductor still functional?

[WhiteFireDragon]

I have a audio DAC that has one of the top pieces cracked, however all the coils are still intact and tightly wound. Should I get it replaced, or will this not affect the functionality of it? Picture of the crack below:

If U101 gets hot in operation (or other things act funny?), it should probably be replaced, yeah.

If the central stem of ferrite is cracked and loose, it should probably be replaced.

You can try supergluing the bits back on.  Ferrite and superglue work nicely together.

So just to confirm, that part that chipped off does not provide any electrical or thermal functionality? The central stem and copper coils seem to be all good.

And can someone help me source a replacement for this damaged inductor? The only indication on the it is "102", and that's not enough info for me to find the same part number.

The black ceramic provides a path for magnetic fields.  By having somewhat less material, the inductance value will be lower.

It's probably not far out of tolerance (-20%, maybe?), which I would guess is still close enough for the nearby components.  But it might not be, hence my warning.

"102" is most likely 1mH.  The current rating will be determined by the wire size... which is determined by how big the thing is to begin with.  What diameter and height is it?

You could also check DC resistance, but it's probably under an ohm, so you'd need a special meter to be sure.

The package is a standard format from e.g. Bourns, etc. and probably costs under $1 (you'll spend more on shipping and handling).

you could super glue them back on, far better than not having them

Is that an ODAC? If so, the same happened with me, still works well.
