TDK WCT Wireless Charging Coil features pattern coil technology that reduces thickness to cover a larger charging area in a single cell. While wireless charging coils are generally produced by winding wires, the WCT series has a unique design that makes it possible to manufacture using a thick copper pattern on a thin film. This design, combined with TDK’s proprietary magnetic material, has reduced the coil thickness to 0.76mm. TDK WCT Wireless Charging Coil offers a thin diameter that allows for one coil in wireless charging systems where three coils are generally necessary, enabling overall system miniaturization.
