Heat Bondable Litz Wire 0.05mmX37X5 Polyurethane Enamelled Wire 185 Strands
Professional multi-strand self-bonding litz wire, designed for high-frequency coil winding. It minimizes skin & proximity effect loss, features fast thermal bonding and stable insulation, ideal for high-efficiency industrial and consumer electronic coils.
-
185 Strands Litz Structure: 5 bundles × 37×0.05mm ultra-fine OFC strands, drastically reduces AC resistance and high-frequency power loss.
-
2UEW Double Insulation: Class F 155°C heat resistance, ≥1500V breakdown voltage, excellent abrasion and voltage resistance.
-
Fast Self-Bonding: Bondable via 130–155°C hot air , no extra glue, supports automated winding & stable coil shaping.
-
High Purity Copper: 99.99% oxygen-free copper, low DC resistance, low heat generation and long service life.
-
Standard Compliance: RoHS, REACH, UL, ISO9001, IATF16949 certified for global sales.

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.
