Planar coils

Planar coils

In contrast to conventional coils, planar coils have no winding. They are manufactured as printed conductor paths. This achieves a higher power density and efficiency compared to wire-wound versions. This coil category is used in domestic appliances, in telecommunications and industry, for example. Planar coils are installed in switch-mode power supplies as well as in regulation and control units, or as overload protection.
