| I am wanting to wind my own 10H choke. Any good info on the web as far as gauge and number of turns ect that you know of? Thanks. |

Hi Tim,
I've been thinking about trying this too. Just sort of practice to trying output transformers. There is a good section in RDH4 that walks you through all of the calculations. I don't remember any good web sources, but will check some of my links.
Sherman-That calculator is for an air core inductor not an iron core choke. Good for RF or speaker crossovers, not so good for filter chokes.

I wonderd why I was coming up with a 15 pound monster choke

| Are there any guidelines or calculators for winding fine silver wire chokes or inductors? |

Silver is almost the exact same as copper except for color and price. Nothing changes, except maybe a slight increase in current capacity. Much more benefit using say, GOSS as opposed to a NOSS core.
Hey Tim, I'd go with 2 or 3000 turns of wire adequate for the current draw, on a gapped core of sufficient size to hold the wire. You can use SWAG's to find such things as winding area needed, based on turns and wire diameter. I happen to have a table for all those figures though. :D
If it's for a pi filter, you can space (random) wind, just put the wire on evenly in semi-layers. If choke input, you'll need to wind even layers and insulate between each with a strip of plastic or paper.

If you use silver wire as hook-up wire etc. in your system it does make alot of sense to use it throughout.
Cheers,;) |
