WPT Tile in WPT System
Role of the Ferrite Tile
The ferrite plate suppresses interference between the antenna pad and metal housing. The plate also keeps the flow of magnetic flux clean between the transmitting and receiving antennas, contributing to improving the efficiency of WPT systems. KEMET BH1T ferrite material has been developed specifically to maintain low core loss characteristics over a wide temperature range, which improves the efficiency of the wireless charging power supply system from room temperatures to high temperatures.

How to Select the Ferrite Tile
Designers should select the size of the ferrite tile according to the size of the antenna pad and select the thickness of the ferrite plate according to the capacity of the WPT system. In particular, it is important to choose the optimum thickness because the characteristics deteriorate when the ferrite material is saturated.
