Introducing the 15W 6.3uH A11 Wireless Transmitting Coil Charger Coil - a high-performance, Qi-compliant wireless charging coil engineered for efficient and reliable power transfer in modern wireless charging systems.

Product Overview
This A11 coil is designed according to the Wireless Power Consortium (WPC) Qi standard, featuring an inductance of approximately 6.3 µH and optimized for 15W power transmission. It is constructed with high-quality multi-strand copper wire (typically 17 AWG litz wire with 105 strands of 40 AWG) to ensure minimal power loss and stable current flow. The coil is shielded with a 0.5 to 1.0 mm thick Ni-Zn or Mn-Zn ferrite layer that extends beyond the coil diameter to enhance magnetic efficiency and reduce electromagnetic interference (EMI). Its compact 50mm diameter and slim profile make it ideal for integration into wireless charging pads, smart furniture, automotive in-cabin chargers, and portable accessories124.
