High-Frequency 2UEW-F 0.071mm x 60 Strands Litz Wire For Inductors
Our 0.071mm x 60 strands Litz wire is engineered for high-performance power electronics requiring superior efficiency at high frequencies. By utilizing 60 individual strands of 0.071mm high-purity enameled copper wire twisted in a precise geometric pattern, this product significantly minimizes the skin effect and proximity effect—the primary causes of power loss in high-frequency AC applications.
This specific configuration (without an additional outer textile or tape sheath) offers an ultra-compact diameter, making it the ideal choice for designs with strict space constraints where maximum copper fill factor is required. Each strand is coated with a high-grade solderable polyurethane insulation, allowing for easy termination without the need for manual stripping.

- Reduced Power Loss: Effectively lowers AC resistance and heat generation in high-frequency circuits.
- Space-Efficient Design: The "bare" (unserved) construction ensures the smallest possible outer diameter for dense winding.
- High Flexibility: The multi-strand structure provides excellent mechanical flexibility compared to solid wire.
- Solderable Insulation: Simplifies the manufacturing process with direct soldering capabilities.
