What is the difference between MWS TwistiteTM and Litz Wire?
Both are twisted multi-conductor products that find use in RF applications but otherwise the two are substantially different. While litz wire may be produced with 15 or fewer individual strands, for high frequency applications the constructions often consist of many bundles with up to 2000 individual strands of ultrafine wire. Litz wire is constructed with a loose lay (<0.25 to 2 twists per inch) to minimize the lineal increase in resistance produced by twisting and individual wires are insulated with single build insulation to maximize the cross sectional area of copper conductor. Polyurethane base insulation is used almost exclusively for the individual wires due to its low RF loss characteristic, wide availability and moderate cost. The constructions of fine and ultrafine strands may be helically wrapped with nylon or other textile yarn to bind and maintain the litz wire in a circular configuration and to protect the thin film insulation coatings from abrasion. In recent years extru
