WebbDepending upon fixed or variable RF coil design suitable core need to be choosen and any conductor such as insulated thin copper wires are wrapped around the core. Material of the core is selected based on the operating frequency. For variable inductor shielded slug tuned inductor form is used. Webb31 mars 2024 · Author: Technical Editor Category: Electronics Articles 31 Mar 17. The variable inductor having an adjustable ferrite core is known as slug tuned inductor. The value of inductance increases or decreases respectively, due to the movement of a ferrite core into or out of the coil winding.

Webb7 mars 2024 · Tuning inductors can be either air-, ferrite-, or powdered-iron-core coils. The air-core coils are not adjustable unless either an expensive roller-contact mechanism or clumsy taps on the winding of the coil are provided. However, the ferrite- and powdered-iron slug-tuned core coils are adjustable.
