PET Film for Choke Coil

PET film for choke coil use provides thin, reliable insulation inside inductors and other magnetic components. It is placed between winding layers, around bobbins and between the winding and the magnetic core, keeping the copper wire isolated and the coil structure neat and stable. The film is tough enough to withstand winding tension, yet thin enough to save space in compact power supplies, filters and electronic modules. It can be slit into narrow tapes, cut into small pieces or die-cut to fit different coil shapes. Its smooth surface wraps flat and stays in place after winding, and it resists moisture and common varnishes. Custom widths, thicknesses and samples are available for your coil production.
