wirewound non-inductive 1% resistors

GAK · 3rd September 2003, 02:55 PM

Does anyone know where I can find wirewound non-inductive 1%4 and 10W resistors in Europe?I want to avoid to put metaloxide.I'd like to find something like Caddock and Mills.

Thanks

Wire-wound non-inductive resistors don't exist

They are less inductive than regular ones.

Real good resistors (one of the best) is Cool-Pak from Caddock.

Are you going to use them in a loudspeaker filter? Then I'll guess Cool-Pak is too much maybe, too expensive?

Yes I need them for my crossover.
What do you think is better to use?

Use the high power resistor with the white rectanglar ceramic case come in various wattages 3w,7w,10w and many different ohms.[These type are very cheap] 19 p each inc vat

GAK, just get some Mills. There will be suppliers like Audiokit in Europe, or else import some. Postage will be minimal.

The ceramic "white coffins" sound awful.

Yes the ceramic white usually are very nasty sounding.
Try RS Components.They have very nice Welwyn wirewound power resistors here: http://www.infoel.rspolska.com/cgi-b...oid=-988923345

They have 2,5 : 6 : 9 and 12 Watt ones that look like this:

The Welwyns are very good for the money. I have a big box of them that I use for prototyping in amps.

Hi,

According to manufacturers they DO exist...

To you and me, in absolute sense of the word, they don't.

Do we agree?

Cheers,

Apart from the microscopic measure, I think the term "inductive" needs to be clarified in this case (at least for me). If a resistor reacts against a magnet bar, what do you call this resistor?

In my current Aleph setup I use Painton wirewound (made in England) for the MOSFET Source. This resistor doesn't react against magnetic field, as opposite to Dale resistor (The common black one)

There are debates about resistor performance. In this case it will be less subjective because the implementation would be in the crossover, probably in series with the tweeter. And anybody know why it has to be wire-wound?

After trying several expensive resistors in audio circuits, hell, I had to go back to the Allen Bradley (Carbon Composite). I have never done much experimentation on crossovers, but since then I also used Allen bradley in my crossovers. Weird? Yes, but my imagination told me that I could "hear" the difference with Dale, Ceramic, VTM, Panasonic (the cheap green one) and several unknown resistors. Exactly the same effect as it's use in audio circuits. I wonder if anyone have ever tried this resistor in crossovers and would report the result.

Oh, and I always agree with Frank. I believe Peranders also will.
