Litz Wire

Wire sold in less than full reel quantities (cut to length wire) is non-returnable.
 

The term litz wire is derived from the German word litzendraht meaning woven wire. Generally defined, it is a wire constructed of individually film insulated wires bunched or braided together in a uniform pattern of twists and length of lays.

The multistrand configuration minimizes the power losses otherwise encountered in a solid conductor due to the skin effect or tendency of radio frequency current to be concentrated at the surface of the conductor. In order to counteract this effect, it is necessary to increase the amount of surface area without appreciably increasing the size of the conductor. It is also essential to position each individual strand in the litz construction in a uniform pattern moving from the center to the outside and back in a given length. Efficiency of the stranded conductor can be multiplied by increasing the number of twists per foot. Generally, six to eight twists per foot is common. All three of our selections have 40 twists per foot, creating a much more electrically efficient and costly to produce.

Our Litz wire was made by Kerrigan Lewis. The current industry standard insulation is a polyurethane film for insulating individual strands because of its low electrical losses and its solderability. Additionally, our wire has "Heavy Nyleze", an extra thick coating. THIS FILM BURNS AWAY IN THE SOLDERING PROCESS! Some litz wires are further insulated with a single or double wrap, or serving of a textile, typically nylon. Our 12/36 is so covered. The 7/36 and 8/36 are unserved.
