Litz wire

Construction

• Conductor: Enamelled copper wire can be solderable or Non-solderable in Grade 1 (1 layer of enamel) or Grade 2 (2 layers of enamel).

• Stranded: Conductors arranged in concentric layers (7, 19, 37). The formation and the number of wires, depends on the section and the working frequency of this.
• Insulation: Wire of tape the different material (textile or plastic) depending on the temperature and environmental conditions.

Characterisstics

Litz Wire typically is used in applications operating within a frequency range of 10 kHz to 5 MHz. For products operating beyond this frequency range, special litz products may be supplied. Individually insulated single conductors make up the basic components of any litz construction whereby electrical current flows evenly distributed through each conductor cross section at higher frequencies.

Application

High frequency litz wire is either used for frequency or heating-related applications. Ultra fine litz wires provide solutions for both technologies regardless of frequency or impedance range. Electrical, mechanical and cost aspects need to be considered carefully during the design phase.
