Grade 2 Enamel Layer Self Bonding Polyurethane Litz Wire 0.060mm×20 Strands For Chock Coils
Overview
This 0.060mm*20 strands self-bonding 2UEW Litz wire is made of 20 pieces of 0.060mm Class 2 polyurethane enameled round copper wires twisted together. Each single wire adopts Class 2 uniform polyurethane insulation with outer thermal self-bond coating, featuring H-grade heat resistance and reliable dielectric performance. It delivers excellent direct solderability without enamel stripping, simplifying terminal welding processes. The stranded structure effectively reduces skin effect and proximity loss under high-frequency operation, making inductance performance more stable for high-frequency coils. Low surface static friction ensures smooth feeding on high-speed winding equipment, with tightly controlled overall outer dimension to keep consistent winding density. The self-bond layer melts under heating to bond strands firmly and fix coil shape without auxiliary fixtures.

Product Features
20 Strands of 0.060mm Grade 2 UEW Single Wire
Each conductor is coated with uniform grade 2 polyurethane insulation, stable dielectric strength, good resistance to thermal shock and softening breakdown.
Thermal Self-bond Coating
Outer self-adhesive layer melts after heating treatment, tightly bonding all strands together to fix coil shape without extra fixing jigs. Consistent bonding film thickness on rounded edges guarantees reliable adhesion
Smooth Surface with Low Static Friction
Uniform coating reduces friction during high-speed automatic winding, preventing paint peeling and wire breakage; tight overall outer diameter tolerance ensures neat winding layers
Outstanding Direct Solderability
No enamel stripping needed before soldering. The polyurethane coating vaporizes rapidly under soldering temperature to form full, glossy solder joints and improve production efficiency
Applications
- High-frequency Transformers
- Wireless Charging Coils
- High-frequency Inductors
- Precision Electronic Coils
- Audio Electromagnetic Components
