Oval Ferrite Wireless Charging Coil Product Case

Our oval hollow wireless charging coil is a thin planar copper induction coil built with ferrite backing, designed for consumer electronics, smart home devices, wearable gadgets and custom wireless charging modules. Combining precision copper winding with ferrite magnetic shielding, this coil delivers stable energy transfer, low magnetic leakage and high charging efficiency. Flexible adhesive base enables quick assembly for mass production projects.

• Ferrite Magnetic Shielding: Built‑in ferrite sheet suppresses magnetic flux leakage, improves charging conversion efficiency and reduces heat generation during operation.
• Oval Hollow Planar Structure: Slim oval hollow design saves internal device space, suitable for products with limited inner layout height.
• Precision Copper Winding: Neatly wound copper wire ensures consistent inductance parameters, stable output and reliable long‑term performance.
• Flexible Black Adhesive Base: Self‑adhesive backing for easy sticking and installation, fits curved and flat housing surfaces.
• Low Heat Generation: Optimized winding‑ferrite matching minimizes temperature rise under continuous working condition.
• Customizable Support: Custom inductance, coil dimension, wire length and terminal options available for OEM & ODM requirements.
• RoHS‑Compliant Material: Environmental friendly raw materials, meets global electronics safety standards.
• Bulk‑ready Supply: Factory mass production capacity, stable lead‑time, MOQ for wholesale orders.

This ferrite wireless charging coil is widely adopted in multiple wireless power‑supply projects:

• Consumer wireless chargers, desktop multi‑function charging stations
• Wearable devices: smart watches, smart bracelets, TWS earbud charging cases
• Small smart home appliances, portable handheld electronic equipment
• Medical small‑size wireless power supply modules
• Custom equipment requiring oval‑form‑factor wireless charging solution

One of our customer projects for portable desktop wireless charger: The customer needed an oval‑shaped charging coil to fit their slim charger shell, with strict requirements on coil thickness, anti‑leakage magnetism and low heating.

We supplied our oval ferrite wireless charging coil with pre‑attached black adhesive sheet. Thanks to ferrite shielding layer, magnetic field is well‑confined. Precision winding guaranteed tight inductance tolerance. The self‑adhesive flexible substrate simplified SMT‑free manual assembly on production line.

After integration test, the finished charger achieved steady charging efficiency, low surface temperature during full‑load operation, and passed EMC related tests. Our flexible customization service also helped the client adjust wire length and terminal style to perfectly match their PCB layout.

• Source factory production, ferrite + copper coil one‑stop manufacturing
• Support non‑standard dimension, inductance and wire terminal customization
• Strict parameter testing before delivery, consistent batch performance
• RoHS compliant, available with relevant certification documents
• Wholesale bulk supply, stable delivery for large‑volume orders
