0.290mmX7 Basic Litz Wire 155 Class F Polyurethane Enameled Copper Wire 2UEW Insulation

0.290mm*7 | 2UEW Litz Wire | Class F 155°C

This Litz wire consists of 7 strands of 0.290mm polyurethane enameled copper wire with 155°C F-class temperature resistance. The stranded structure reduces high-frequency skin effect to lower power loss and heat generation. It features consistent insulation and stable conductivity for smooth winding and long-term stable operation. PN400B large bobbins are available to reduce waste from frequent reel changes and improve material utilization.

Key Advantages
  • Low High-Frequency Loss: Optimized multi-strand structure reduces skin effect and heat generation for higher working efficiency.
  • Stable Insulation Performance: High-quality polyurethane enamel ensures uniform insulation, strong dielectric resistance and stable electrical performance.
  • F-Class Thermal Stability: 155°C heat resistance and anti-aging properties support long-term continuous operation.
  • Excellent Winding Performance: Superior flexibility and tensile strength avoid strand breakage during high-speed winding.
  • Low Material Loss: PN400B large-bobbin production reduces reel change frequency and effectively cuts wire waste.
Applications

Suitable for high-frequency inductors, transformer coils, power inductors, electromagnetic coils, motor windings and various conventional precision electronic winding components.

FAQ
  • Q1: Why choose Multi-strand Litz wire?

    A1: Ultra-multi-strand design minimizes high-frequency impedance loss, greatly improves coil efficiency and Q value, ideal for professional high-frequency equipment.

  • Q2: Can it be soldered directly?

    A2: Yes. Remove outer silk layer first, then the PU enamel can be directly soldered with fast and firm welding effect.

  • Q3: Can you provide customization?

    A3: Custom strand count, wire diameter, stranding direction and packaging are supported for prototype and mass production.
