Inductive Components - Inductors for Power and Signal lines
What are inductors?
An inductor is a passive electrical component with two terminals which stores energy in a magnetic field when electric current flows through it. Typically, inductors consist of an insulated wire wound into a coil.
What is the purpose of an inductor?
Inductors can be used in combination with capacitors, which complement the function of inductors, to form LC filters that can separate the required signals from unwanted ones. Also, voltage regulating converters are stabilized when used in combination with inductors that can store magnetic energy, capacitors that can store electric energy, and a switch.
Inductors vs. Chokes
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.
Inductors are mainly used to clean differential noise for both signal and power lines while Chokes are mainly used to clean common mode noises. Inductors are also used for storing electric energy and further stabilizing power performance.
