| Keywords: Ferrite slug tuned inductor with pot core.JPG inductor used in radio circuits About 4 2 cm 1 5/8 inches tall It consists of a wire wound around a plastic form with a threaded ferrite slug down the center visible at top The slug can be turned with a hex wrench to move it into or out of the coil Moving it further into the coil increases the permeability increasing the magnetic field and thus the inductance Another part of the ferrite core dark cylinder called a pot core surrounds the wire winding This serves to confine the magnetic field lines so they don't induce currents in other nearby components causing electromagnetic interference It is probably used in bandpass filters in the intermediate frequency IF section of radio receivers to filter out interference from radio stations near in frequency to the desired station 2013-07-06 08 00 49 own Chetvorno cc-zero Uploaded with UploadWizard Ferrite inductors | ||||
