The wire with high thermal class, Zero-defect strengthened insulation and high voltage resistance compliance with IEC60317-56（publication 2012.05）/IEC60950U. with nominal conductor diameter 0.04mm to 1.6mm, class 180ºC.

• OBJT2 UL approval
• MW85-C NEMA standard (UL file No.E158033) Cat. Number FIW

The wire can meet the requirements of miniaturized components, good winding performance and low cost, applied small transformer, electronic switch etc. The wire is the best substitute material for TIW (Triple Insulated Wire).

Our Magnet Wire “FIW” over 30 times coating meet to the following Grade of FIW3, FIW4, FIW5 up to FIW9 e.g. FIW3 0.050mm wire Max Overall Diameter 0.072mm and Min. Breakdown Voltage is 3,000 Volt. FIW8 0.050mm wire Max Overall Diameter 0.127mm and Min. Breakdown Voltage is 8,000 Volt.

Features

1. High thermal class 180ºC ;(only 105ºC-130ºC for TIW Single and Multi-layer Insulated winding wire);

2. High break down voltage ＞15KV;

3. High insulation resistance, 6000Vrms,1min;

4. Solderable, 390℃, 2s；（no need to peel insulation）;
