Advantages of FIW

+   choice of different insulation builds (with different insulation thickness), allows optimization of products like smaller transformers, and gives a cost advantage

Example: 0.25 mm, FIW 7, 390°C, 2.4 seconds
Solderability of 0.25mm FIW 7

+   excellent solderability    

+   superior windability

+   high temperature class of 180 °C acc. to UL 60172, thermal life time acc. to UL 2353 Annex U approved for transformers with temperature class 130 °C
