Baked varnish coil

A baked lacquer coil is an air-core coil , i.e. an inductive component without a soft magnetic core. Baked enamel coils consist of enamelled copper wire that is provided with an additional layer of thermoplastic enamel. The lacquer layer is liquefied during the winding process by hot air or electrical surges and then hardens. This leaves a mechanically stable and self-supporting composite that can do without a core.

The baked enamel wire, also known as adhesive enamel wire, is usually made of copper and is coated with insulating varnish in the first step before the adhesive varnish layer is applied.
