Würth Elektronik Qi Wireless Power Charging Coils
Würth Elektronik Qi Wireless Power Charging Coils (WE-WPCC) allow power to be transferred wirelessly through inductive coupling. These charging coils and receivers go beyond the Qi standard of 20W with many of the coils capable of handling up to 200W. They come with a transmit coil and the receive coil. The coils are inductively coupled and the AC current in the transmit coil generates a magnetic field that induces a voltage in the receive coil. Würth Elektronik WE-WPCC Qi Wireless Power Charging Coils are wound with litz wire rather than bifilar and offer outstanding performance with low DCRs and high Q values. When used together, these transmit and receive coils achieve an efficiency of up to 93%.
Features
- Qi-standard compliant
- Uses litz wire with high Q value
- Applicable for up to 20W (up to 200W outside the standards)
- High permeability shielding
- High reliable construction
- Pot core construction limits the stray field in the design
Applications
- Wearables
- Energy, gas, water, and smart meters
- Home and building automation
- Access, light, climate, and remote controls
- Alarm and security systems
- Health and fitness
- Portable medical devices and remote diagnostics
- Portable devices used in a clean area
- Smart accessories
- Consumer products
- Digital cameras, baby phones, walkie-talkies, remote controls, smartphone sleeves, and watertight products
- Explosion-sensitive area where the use of a physical connection is hazardous
