The size of new Tx - coil assembly（L*W*H） is 57*48.5*2.9mm for the function of wireless charging, which are made of Ni-Zn ferrite shielding materials and Litz wire winding. It is ideal for wireless charging transmitter coil assembly and increase the charging efficiency.
Inductive Coupling: good coupling between two coils, a transmitter coil and a receiver coil. An alternating current in the transmitter coil generates a magnetic field which induces a voltage in the receiver coil. This voltage can be used to power a mobile device or charge a battery.
