0.080mm Self Bonding Wire Solderable Enameled Wire For Transformers / Charging Coils

Overview

This thermally self-bonding solderable polyurethane enameled round copper wire consists of uniform polyurethane primary insulation and an outer heat-activated self-adhesive layer. The wire features reliable dielectric strength, outstanding resistance to thermal shock and softening breakdown, and stable long-term heat resistance. Its core advantage is direct solderability: the polyurethane enamel can be melted off quickly during soldering without mechanical stripping, greatly simplifying coil terminal processing. After heating, the outer self-bond coating melts and firmly adheres adjacent wires together to lock the coil shape without additional fixing fixtures. The finished outer diameter is controlled within tight tolerances, paired with a smooth low-friction surface to support stable high-speed automatic winding.

Product Features

Thermally Self-bond Outer Coating
The adhesive layer melts upon heating to tightly bond wires together, locking coil shape without extra fixtures. Even bonding film thickness ensures consistent adhesion effect

Direct Solderable Polyurethane Insulation
No enamel stripping required before soldering; insulation vaporizes rapidly at soldering temperature to form complete, smooth solder joints and improve production efficiency

Stable Insulation Performance
Uniform polyurethane primary insulation with reliable dielectric strength, excellent resistance to thermal shock and softening breakdown, effectively preventing inter-turn short circuits

Complete Specification Coverage
Rich standard wire gauges in stock; customized sizes are available to meet diverse coil manufacturing demands

Applications

High-frequency Transformers, Power Supply Transformers, Wireless Charging Coils, Precision Micro Motors, High-frequency Inductors, Audio Components
