Abstract
An inductor coil is made with winding turns in a conical shape, tapered from a very small diameter and gradually increasing. The core of the coil is composed of a dielectric material with a colloidal suspension of magnetic particles, i.e. poly-iron. A heatsink, such as a wire or ceramic rod, is partially embedded in the core. The heatsink functions to remove heat from the core, thereby reducing the temperature rise during inductor operation. The reduction in temperature rise permits operation at currents above 1.0 amp while preserving high-frequency performance.
