Fixed Inductors

An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. Inductors are widely used in electronic circuits for their ability to control the amount of current in a circuit, to block direct current while allowing alternating current to pass, and to filter unwanted signals. They are also used to couple signals from one circuit to another.

Application Field

The VLF252010MT-3R3M-CA is a monolithic fixed inductor that has a high quality factor and low DC resistance, making it suitable for a variety of power applications. It has an inductance of 3.3µH and a maximum current of 2.38 A at 23 °C. Its operating temperature range is -55°C to +125°C, and its maximum height is 2 mm. This inductor is ideal for use in high-current power supplies, DC-DC converters, and other power management applications.

Working Principle

A fixed inductor works on Faraday’s Law of Induction, which explains that if a conductor is placed in a changing magnetic field, a voltage will be induced in the conductor. When current passes through the coil, it sets up a magnetic field, which builds up a magnetic flux around the coil. This flux induces a voltage in the coil, which opposes the current flow. This opposition is called inductive reactance. This electrical opposition of an inductor is defined by Henry’s law, as the ratio of induced EMF to the rate of change of current. This opposition restricts the flow of current which can be used to provide resistance in the circuit or to protect the circuit from any overload.
