TAPED POLYIMIDE FILM COVERED COPPER LITZ WIRE 0.1*60 CLASS 180 POLYESTER INSULATION
Taped high frequency litz wire constructions are mainly suitable for applications requiring a high break down voltage. Taping gives litz wire improved capability to withstand flexing and mechanical stress. Self-adhesive tape material increases protection against re-opening during and after manufacturing processes and thus secures the compliance with defined creepage distance.
APPLICATION
transformer/ Inverters/RF transducers/RF chokes/Inductive charging
