TDK has introduced a thin pattern coil to support the wireless charging of next-generation mobile devices. The WCT38466-N0E0SST101 was developed without employing conventional lithographic exposure/etching techniques. Instead, TDK's process technology was leveraged, in combination with plating technology using the nano dispersion of the organic compound polypyrrole, as developed by Achilles Corporation.
Although wireless charging coils have generally been produced by winding wires, this new approach has made it possible to manufacture them using a thick copper pattern on a thin film. This, together with the application of TDK's proprietary magnetic materials, has enabled coil thickness reduction down to 0,76 mm, which is approximately one-fifth the thickness of traditional 3,8 mm diameter wound-wire coils. Furthermore, the use of TDK’s original optimal coil shape pattern means that the new coils cover a larger charging area.
The wireless transfer of power to mobile devices, such as smartphones, has considerable appeal. Uptake of demand for wireless charging is being seen in home, office, retail and automotive environments. With their dramatically thinner diameters, the TDK coils, which are compliant with the Wireless Power Consortium’s widely adopted Qi standard, will open new opportunities for wireless charging deployment. In addition, while it was previously necessary for three coils to be incorporated into wireless charging systems, now only one coil will be required, thereby enabling system miniaturisation.
The pattern coil has dimensions of 85 x 67 x 0,76 mm, with an inductance of 10,6 µH and a resistance of 0,139 Ω at 100 kHz.
