Custom manufacturing of coils for wireless power transmission (prototype support available)

We can manufacture according to your requirements, such as size, wire material, and inductance. Prototype support is also available.

We are winding Litz wire to reduce the skin effect. We can manufacture according to your requirements, including coil size, wire material (Litz wire, solid wire), target inductance, and more. In addition to winding, we also support processing such as PCB mounting and various evaluations.
