WHAT IS FIW?

Fully insulated (FIW) zero-defect enamelled round copper wire is the wire with high thermal class, Zero-defect strengthened insulation and high voltage resistance compliance with IEC60317-56 / IEC60950U and NEMA MW85-C. FIW is an alternative wire to build electronic transformers typically using TIW (Triple Insulated Wires)The wire can meet the requirements of miniaturized components, good winding performance and low cost, applied small transformer, electronic switch etc.
