Wireless Charger Coil
Large Flat Rounded Square Air Core Coil, High-Density Multi-Turn Copper Winding, Wide Sensing Range For Large-Size Wireless Chargers & Long-Distance NFC Readers.
Product Overview
This large flat rounded square coil adopts high-density multi-turn self-bond enameled copper winding, air-core self-support forming without magnetic core. Extra-large square frame expands effective magnetic coverage area, ultra-thin flat profile fits flat charging pads and large-area card reader equipment, ultra-fine extension leads support convenient PCB soldering.
Core Advantages
- Oversized rounded square outline: Greatly expand signal sensing range, realize long-distance NFC identification and stable high-power wireless charging
- Dense flat multi-turn winding: Higher inductance value under same thickness, enhance magnetic field penetration ability
- Air-core design: Eliminate magnetic saturation and hysteresis loss, stable inductance performance under long-time high-current operation
- High-purity oxygen-free copper wire: Extremely low DC resistance, reduce heat loss and improve energy conversion efficiency
- Fully customizable parameters: Outer side length, inner hollow aperture, winding turns, wire diameter and lead stripping length adjustable
