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. The wire can meet the
requirements of miniaturized components,
good winding performance and low cost,
applied small transformer, electronic switch etc.
UL approvals& VDE approvals:
◆ OBMW2, according to UL 1446, ANSI MW 85-C. File No.E469976
◆ OBJT2,Thermal class F, Reinforced insulation, according to UL60950-1. File No.E469976
◆ VDE approvals(FIW3-FIW9, φ0.04mm to φ0.80mm).
Why FIW?
◆ High thermal class 180;
◆ High break down voltage, up to 15KV;
◆ High insulation resistance,up to 6000Vrms,1min;
◆ Solderable at 390℃, (no need to peel insulation);
◆ High cut-through temperature, 250℃,2s no cut through, Air Reflow ( peak temperature 260℃), no crack;
◆ Color option: natural(N)/red(R)/green(G)/blue(B)/violet(V)/brown(BR)/Yellow(Y);
◆ Very good winding performance, suitable for high speed winding machine.
◆ Min.diameter can be φ0.03-φ0.80mm.
