Where to by inductive wirewounds?

Tweeker · 8th February 2009, 04:34 PM

Im looking for wirewound resistors that are not Ayrton-Perry wound. Are there any in current production or vendors with a good selection of surplus?

I want them for plate loads, RC filters etc.

All the el-cheapo's I get from Digikey show an inductance

Cheers!

Most likely not in the higher values used in tube circuits.

Mills MRB resistors are inductive wirewound. The MRA are non inductive.
If you do a search for "Mill MRB resistor" you can find some different values at a few sites. Welbourn labs list them as non inductive, but then they have a picture of MRA type.

Most likely won't find any past a few hundred ohms or so. You could DIY using really thin nichrome wire and a ceramic form. Better to just add an inductor in series with a resistor IMO.

edit>something like this with 1000V rating (tube plates)

They have some Mills MRB 1k 5 watt, and in 12 watt they have 4k, 10k, 50k, and 82k.
