3500V 2UEW-F-PET(N) 12.1mm×3.4mm Rectangular Mylar Litz Wire For Transformer
Our rectangular Mylar Litz wire is engineered for space-constrained high-frequency applications where efficiency and cost are critical. The construction begins with 0.28 mm enameled copper wire, where 300 individual wires are precisely twisted together and compressed into a flat rectangular profile measuring 12.1 mm wide by 3.4 mm thick. This creates a super high aspect ratio that maximizes conductor surface area while minimizing total height, making it ideal for compact coil constructions.
