Fixed Inductors: 7443631500 Application Field and Working Principle

An inductor, or more specifically a fixed inductor, is an electrical component that stores energy in the form of an electric field or magnetic field when there is a changing current through it. Fixed inductors, also known as non-adjustable inductors, are typically used for either AC or DC applications in electronic circuits. Depending on the design and application, they may be used for switching, matching, filtering, protection, energy conversion, and various other applications.

Design Types

Fixed inductors are typically made from either ferrite or metalized polyester-coated wound cores. The core is wrapped with a copper or aluminum wire that is insulated along the windings. The ferrite core\'s shape must be chosen for its magnetic properties, which determine the inductance of the component. Metalized polyester-coated cores are typically designed in the shape of a cylinder, but can be formed into other shapes with varying inductance characteristics.

Fixed Inductor Classification

Fixed inductors can be categorized by their inductance levels, temperature range, application, and type. For example, inductors with higher inductance levels are typically used for applications such as RF power, energy storage, and power conditioning. Those with lower inductance levels are typically used for applications such as audio and power filter applications. Inductors with larger temperature ranges are typically used in environments with large temperature changes, such as in spacecraft and military applications.

Working Principle

Fixed inductors work by reacting to changing currents. When a magnetic field is generated by a changing current, this causes a voltage to develop across the inductor. This voltage opposes the change in current and this dynamic is known as inductance. Fixed inductors consist of coil windings around a magnetic core, which increases the inductance of the device. The magnetic core material and shape are chosen to increase the inductance levels and provide a required amount of impedance.
