Heat Resistance 0.05mm FIW Wire Enameled Fully Insulated Winding Wire Ultra Fine

FIW (Fully Insulated Wire) is high-performance triple insulated winding wire, serving as an upgraded alternative to conventional TIW wire for switching transformers. A comprehensive range of finished outer diameters is available to support miniaturized transformer design and reduce overall production costs.

FIW delivers superior performance in automatic winding and direct solderability compared to TIW. The multi-layer repeated coating technology ensures uniform, defect-free insulation and stable high voltage resistance. It meets reinforced insulation safety standards without requiring additional insulating sleeves.

• Multiple insulation thickness options enabling transformer miniaturization and cost reduction
• Direct solderable at 390°C for 2 seconds without requiring stripping film
• Thermal resistance up to 180°C with breakdown voltage exceeding 15KV
• Cut-through resistance at 250°C with no breakdown within 2 minutes
• Various insulation colors available
• Outstanding machinability for high-speed automatic winding to boost productivity

Switching transformers, power adapters, fast chargers, network isolation inductors, wireless charging coils, automotive electronic windings, medical safety coils, miniature high-speed motors, and smart meter sensors.
