Hi guys,
I'm trying to make Qİ compliant wireless charger for low power. I'm using the link below.

The problem is I don't know which coil to use for this experiment. For test results it uses a TDK WR222230 but I cannot find it anywhere. Can someone offer me a small coil that can easly fit 4x4 cm box ?
