I finished building my QMX+ today and on inspection I see I've broken the core of L102, one of the switching power supply inductors. It looks like both leads of the winding are still connected to the board. I'm not going to try powering it up until I get a couple of questions answered.

?

1) It looks like the core snapped off almost flush with the bottom flange, which is still attached to the PC board. The ends of the winding are still connected to the board. Would it still work if I just used cyanoacrylate glue to put the core back together?

?

2) If the answer to #1 is "no," can anyone suggest a suitable replacement inductors that's available in the U.S.? Digi-Key doesn't seem to carry anything of similar size that's greater than 220 uH. This one is 330 uH.

Yes, it should work fine if you carefully glue it back together, as long as the wires are not broken.?

?

And if you need a new ones, I have used the 330 ones from this Amazon kit:

Thanks Stan. I never studied magnetics so I wasn't sure how well that little core would react. The wires are still connected and none of the windings have come undone. I'll try gluing it tomorrow.

I saw that kit on Amazon and that's my Plan B.

Thanks again!
