Litz wire 15/46 15/0.04

[qute1]

Got a large amount of Elektrisola Litz wire 15/46 15/0.04 any one got some specs for building a decent 9.7" coil looking for a 250uh a 350uh and a 470uh or in the region but having difficulty inputing the data into the coil calculators cos litz comes out funny and its too expensive to do many trial runs on.
Stuff should be just the ticket for the task but the wastage is intolerable so need to get it in the ball park as can't check it till you cut and solder the ends and if you mess up its heart rending.

If your description is correct, and I am reading the graph correct (its early morning here ) the closest I can see is 16/46, which is supposed to be equal to about 34 AWG, (very thin) figure out what that is in MM, and use the RADIUS of the coil in Q's calculator, but add 1 or 2 turns and work back.

Thanks 6666 i was very lucky to find this stuff i just need to get it right cos it's like snails teeth and don't want to waste it, so was hoping someone had some defo specs from a previous build cos SHOULD be the dogs spuds as far as wire for mono coils are concerned!

Not getting any suggestions. My guess, used the coil calculator. 23T close to 470uH. If less than 470uH calculate T to remove to get 350uH. Calculator gives 20T for 350uH. I'm just guessing, maybe some one that knows could give a better suggestion. 23T calculates about 16 ohms if I did my math right.

Thanks guru green i appreciate that also i will begin there then, i think, because of the the thin ness i will end up with a high resistance coil but should be able to adjust the damping accordingly and hopefully the ringing will be very minimal.

If no more suggestions you should try the coil calculator to check my suggestion.

Q's coil calc is easy to use, use the radius of the size of the coil you want, the size of wire in MM, number of turns = inductance, just alter the number of turns and radius for required inductance
