Wurth Electronics Qi Wireless Power Charging Coils

The only manufacturer with both
a transmit coil and a receive coil on the market!

Wurth Electronics Wireless Power Charging Coils (WE-WPC) allow power to be transferred wirelessly through an inductive coupling at a short range of typically a few millimeters. The new 760308100110 and 760308100111 wireless charging coils feature round base plates. The Wireless Power Charging Coils from Wurth Electronics are Qi-standard compliant and evaluated and approved from several IC manufacturers. The transmit coil and the receive coils are inductively coupled, meaning the AC current in the transmit coil generates a magnetic field which induces a voltage in the receive coil to power a device. The magnetic field between the coils is highly concentrated, exposing the user to only a small leakage field which is further minimized by an EMI shield on the back of the coil.  The coils are winded with litz wire, instead of bifilar, resulting in outstanding performance with the lowest DCRs and highest Q values. When used together, the transmit coil and receive coil achieve an efficiency of up to 75%.
