Flat Wire Transformer

Lower DC resistance, extremely small capacitance distribution, excellent heat dissipation, perfect replacement of common CMC, which is popular used in power line solutions.

  • Product Detail

Key Properties:

  • Comparing round copper wire, flat copper wire with more excellent performance, higher current ( unit current density reach 1.5~2.0 times) & smaller volume (0.5~1.0 times).
  • Lower DC resistance, extremely small capacitance distribution, perfect heat dissipation.
  • Closed magnetic circuit design, small magnetic leakage, stable impedance balance, good conducted radiation effect and EMI effect.
  • Automatic machine winding, which guarantee stable quality, competitive production cost, more time-saving, better quality, higher efficiency during final application.
  • Stronger insulation, extending power lifespan.
