Inductor trouble

[Bassivus]

Hi,

today I got the package with OFC foil inductors I ordered online.
Unfortunately one got broken lexan ring in the middle.
I was planning using them in PSU of amp.
Should I try to repair it or should I ask for replacement. It took 3 weeks to arrive so you understand why I'm considering reparation...

A piece fo wood would do just fine.

Thanks for the reply!
Not very visited part of the forum.

I was thinking similar, or just strap it with the 3 or 4 those nylon straps... you know the type that make trrrrrrt when you fasten them

I would be careful with trrrrrrt (zip ties) and the soft polypropylene isolation.

Go hack a log off your favorite tree, and paint it in a fancy color

Or as I see you have access to the "red" inventory, I bet you can find yourself a nice piece of either polyamide (nylon) or perhaps even easier for you to find, PTFE (teflon).

If you end up in a real tight spot, drop me a mail, and I'll sort you out. I have done a bit of machining of plastics from time to time, and I sure have two small pieces of something nice somewhere.

BTW have you checked the inductor isn't damaged electrically ?

I'm not sure what the insulation rating is on these inductors is but these are usually used for speaker cross overs- i.e., low voltage and high current. If you are making a psu filter there may be a cheaper, more appropriate "iron rich" alternative.

Also, I wonder what must have happened to these to break the middle piece? The inner windings may have loosened which may be less than ideal, as these are wound to be tight and solid.

Hi, I have checked them for conductivity and its fine. Good thing is that they did not get loosened except the first inner row.

They were packed one buy another and my guess is the got crashed inside the package by their own mass inertia when package was mishandled-thrown by post office . They together weight about 1,6 Kg!
