    Customized products could be provided according to the different request.

  • Wireless charging coil

    Wireless charging coil

    According to the needs of the circuit, select the winding method:

    When winding the wireless charging coil, it is necessary to determine the winding method according to the requirements of the wireless charging device circuit, the size of the coil inductance and the size of the coil, and then make a good mold. Wireless charging coils are basically wound from the inside to the outside, so first determine the size of the inner diameter. Then determine the number of layers, height, and outer diameter of the coil according to factors such as inductance and resistance.
