Fixed Inductors

Inductors, also known as coils, are components that consist of a center coil of wire wrapped around a core material. Inductors are most commonly used to store energy from an electric current in the form of a magnetic field and to restrict or “filter” frequencies within electrical circuits. Inductors can be further categorized based on the composition of their core material, winding type, and configuration. The inductor model IHLP1212AEERR47M11 belongs to the fixed type of inductor.

IHLP1212AEERR47M11 Working Principle

The working principle of the IHLP1212AEERR47M11 fixed inductor is based on Faraday’s Law of Electromagnetic Induction. This principle states that a time-varying magnetic field within a conductor generates an electric field. When a constant voltage source is applied to the inductor, the electric field causes a current to flow through the device. This current creates a magnetic field in the inductor, which stores energy as a function of the number of coils, the size of the core material, and the magnetic field strength. When the voltage is removed, the inducted current within the inductor will slowly decay until it reaches zero, releasing the stored energy.

Fixed inductors, such as the IHLP1212AEERR47M11, are designed to store energy from an electric current in the form of a magnetic field. They are ideal for power circuits involving low voltage applications, such as voltage regulator modules, audio circuits, and DC motor controllers. By utilizing Faraday’s law of electromagnetic induction, the IHLP1212AEERR47M11 fixed inductor is able to store energy within a magnetic field created by the current flow in its coils.
