Inductors are metal coils used in circuits. They are able to generate magnetic fields when they carry current. They are also able to induce magnetic fields in wires that are near them.Inductors that are used to help filter signals are called chokes.Choke circuits are formed from a single inductor or a combination of an inductor and one or more capacitors. Choke circuits are low-pass filters since they weed out high frequencies and pass lower ones through.Chokes filter out the AC ripples in power supplies to help ensure a steady DC output. Chokes are also found in circuits such as Colpitts, Hartley, and Clapp oscillators.
A ferrite bead or ferrite choke is a passive electric component that suppresses high frequency noise in electronic circuits. It is a specific type of electronic choke. Ferrite beads employ high frequency current dissipation in a ferrite ceramic to build high frequency noise suppression devices. Ferr..
