What are Inductors and Chokes?

An inductor is a passive electronic component. They are typically formed by insulated copper wire wound into a coil on a magnetic core, made of iron or ferrite, which allows direct current (DC) signals to pass easily.

Inductors temporarily store energy in the form of a magnetic field, measured in units of Henry (H). When current flows through an inductor, a magnetic field is generated and this energy will be stored inside the magnetic field in the coil. If the current flowing through changes, this creates a voltage.

Chokes are a type of inductor specifically used to block high-frequency alternating current (AC) signals while allowing low-frequency DC signals to pass in an electrical circuit. These inductors are referred as chokes as they restrict, or choke, these high frequencies.

What Do Inductors and Chokes do?

Inductors slow down current surges or spikes by temporarily storing energy in the electro-magnetic field and then releasing it back into the circuit. Inductors are useful in conditions that may experience sudden changes in current as the inductor will try to resist any changes. Inductors are often used in AC electronic equipment, Switch Mode Power Supplies (SMPS), security sensors and electronic filters.

Choke inductors reduce AC voltages to very small values, so that a load component, such as a resistor, can receive DC voltages. These unwanted AC signals are known as AC ripples. A choke will filter out the AC ripples in power supplies to ensure a steady DC output.

Chokes are commonly found in electronic filters to separate signals of different frequencies. They are also used in power supply circuits where a public AC mains (line) supply has to be converted to a DC supply suitable for powering electronic circuits.
