Inductor Choices

[chienmort]

A lot of designs seem to offer ICE inductors or wind it yourself on T106-2 cores. At the moment, due to the stupidity of Brexit, it is hard to get those in the UK and confusion over the new import arrangements have put off companies from selling into the UK.

I can get Bourns, Vishey etc at similar values and currents but wondered if there is any particular parameter that I should keep in mind?

Inductance vs current curve flatness.

red better

Thanks DUG.

Don't forget the excellent inductors from Coilcraft. They are from UK.

Thanks to everyone for their input. I have a couple of T106-2 toroids that I will wind myself and I have Coilcraft, Wurth and Murata finished coils on the way. I will try them all.
