Fixed inductors are passive components comprised of coil windings or solenoid-shaped cores made of magnetic materials such as iron, iron-cobalt, and nickel-iron, wound around a cylindrical core. These components are used in a wide variety of electrical and electronic circuits, such as power amplifiers, receivers, transmitters, and radio frequency (RF) and microwave circuits. The purpose of a fixed inductor is to produce a magnetic field around its windings when a current passes through them. The magnetic force of the field can be used to store or dissipate electrical energy.

IM04RU1R2K is an example of a fixed inductor. This component belongs to a family of non-polarized fixed inductors, making it suitable for both alternating and direct current applications. It has a high inductance value of 2.2 mH, making it ideal for use in energy-saving applications, as it generates less electrical noise compared to other inductors. The non-polarized nature of this component means that it can be used in both an AC as well as a DC circuit.

The IM04RU1R2K is constructed with a ceramic body and is covered with a protective coating. It has an operating temperature range of -40°C to 125°C and a rated current of 0.45 amps. The DC resistance of the unit is 1.11 ohms, with an inductance tolerance of +/-20%. It also has a 20-bit accuracy code for fast identification and is RoHS compliant.

The working principle of fixed inductors like the IM04RU1R2K is based on the principle of electromagnetic induction. When an electric current passes through the coils of the inductor, it produces a magnetic field which induces a voltage in the same coils. This induced voltage opposes the change in current and is known as self-inductance. This opposition to current changes is known as inductance. The inductance of a fixed inductor depends on its core material, the number of turns in its windings, the size and shape of the core, and the type and magnitude of the current passing through the core.

The IM04RU1R2K can be used for various applications, such as setting the base current in linear power amplifiers, filtering high frequency noise in power supply systems, and pulse generators. It can also be used in impedance matching circuits, analog signal processing applications, and for controlling or suppressing power surges.

To sum up, fixed inductors like the IM04RU1R2K are an important passive component in many applications. They are constructed with coil windings or core materials made of various magnetic materials, and generate a magnetic field when a current passes through them. Their working principle is based on the principle of electromagnetic induction, where an induced voltage opposes any changes to the current passing through the core, causing inductance. The IM04RU1R2K is a non-polarized component with a high inductance value, making it suitable for AC and DC applications, as well as for various energy-saving applications.
