Anyone know where I can get a 0.5h, 3A, 0.5ohm RDC inductor?

Hi everyone -- the subject line pretty much says it all, but in addition, I'm based in the UK, so a U.K./EU supplier would be mildly preferable...

Many thanks!

Jens

I do not know which values are critical - and whether you are doing impedance or DC resistance in ohms, or the application.

0.5H, as in 500mH?

You're probably going to need a custom reactor. In the EU, I'd try http://www.lundahl.se or http://www.sowter.co.uk

Be prepared to pay through your nose in € or £ though for that much VA in a reactor :hot:

Good luck!

Yes, 0.5H as in 500mH (not 500uH, Chris, I'm afraid, but many thanks for your reply anyway). I was worried the answer would be "wind your own..."

Any off the shelf solutions?

Thanks again, everyone!

Two of these in series should do. Ties up some real-estate, but will get the job done. I doubt the difference in resistance will matter to the design.

Wow -- this is going to be expensive... I need one for each channel...

Thanks everyone! Really helpful.

Kind regards,

Jens
