We are a reliable source for many of your litz wire and crystal radio part needs. Since 2008, we've sold more than 19,000 orders with excellent customer feedback. Please visit our eBay Store at mkmak222_Litz Wire to see what is currently available.
We have over a hundred types of litz wire in stock. They contain 5 to 1725 strands of AWG 48 to 28 (0.03 mm to 0.32 mm) wire. The litz wire's equivalent AWG are from AWG 36 to AWG 4.
If you don’t see a particular type of litz wire that you're interested in, please contact us so that we can help arrange a custom order. We can usually have these delivered in three weeks. Large orders may be purchased at the wholesale price.
Most orders will be shipped within one day. The small amount of wire will be coiled on 6” or 7” diameter paper spool to prevent the destruction of the litz wire structure. Larger amounts will be coiled on the original plastic spool.
Note: For avoid damage the structure of the small Litz wire, please observe photo “How to un-coil litz wire from the spool" on my eBay List.
When winding a coil, in order to smoothly un-coil the Litz wire from the paper spool, the simple method is: Vertically fix a 1/4-inch diameter screw rod on a flat plate, and then put paper spool into screw rod flat. When you pull out the litz wire from the paper spool, the paper spool can rotate freely on the screw rod, and the litz wire will not be twisted and knotted.
You only need an electrical solder iron to solder the litz wire. When you heat the end of litz wire, the polyester yarn insulation will be melted and recoiled, the polyurethane insulation that covers on copper strands wire will be completely volatilized, and the copper wire will be tinning.
Here you are bidding on a 100
feet spool of brand new 660/46 Litz wire. This type 2 litz
wire contains 660 strands of individually insulated AWG #46 (~ 0.04 mm)
enameled wires, equivalent to AWG #18 single wire. Its outer diameter is <1.71
mm.
This Litz wire was manufactured in China and is RoHs
compliant. It uses Polyester fiber for the outside insulation and Polyurethane insulating film for each copper
strand. It is very easy to solder with a simple 60 watt soldering
iron.
The recommended operating frequency for Litz wire with AWG 46 strands is 850 KHz to 1.4 MHz, best for make High Q Coil, trap, or loop antenna for Amateur radio and Crystal Radio.
Please notice, not all 660/46 Litz wires have the same spec, even they come from the same manufactory. When I first order Xizi brand 660/46 Litz wire and compare it with US made Kerrigan-Lewis brand, the Q factor of Xizi brand were average 200 - 300Q lower from 500 - 1700 KHz. I find out they have different structure. Then I ask the manufactory change the structure for my new order, Now you can see, the Q factor improve a lot!
I test this 660/46 Litz wire and able to made some very high quality coils, their Q factor can be reach over 1472Q on 805 KHz ( with HP 4342A Q meter, -3dB method )
I compare
the US made Kerrigan-Lewis brand 660/46
Litz wire and this new 660/46 Xizi brand Litz wire,
the Xizi even better than Kerrigan-Lewis.
Here are two coils made from these Litz wire with high-impact styrene tube. Some one checked these two coils with HP 4342A Q meter by -3dB method:

If you need longer wire, please order more Quantity at the same time so we can give you the whole length in one piece without discontinuity. Please contact us for your specific request.
We have hundreds of sizes of Litz wire for sale. Please search in my eBay Store mkmak222_Litz Wire . When you search for litz wire, use the key word format “xxx/yy”. For example, if you are looking for 660 strands of AWG 38 litz wire, enter key word “660/38” to search (“660” is the number of strands, “38” means the strands are used AWG 38 enameled wire)
