Fiw 4 Class 180 Enameled Magnet Wire High Voltage

FIW4 wire 0.335mm class 180 high voltage enameled copper wire

FIW (Fully Insulated Wire) is a wire product that can replace traditional TIW (Triple Insulated Wire) for the production of switching transformers. Because FIW has a wider range of outer diameter finishes, it allows customers to produce smaller transformers at a lower cost.

At the same time, compared with TIW, FIW has better winding performance and welding performance. FIW uses a multi-layer coating process to ensure reliable and defect-free insulation.
