Fixed inductors, also known as "fixed chokes" or "fixed REACTORS", are components used in a variety of electrical applications. A fixed inductor consists of a winding of wire around a solid core, which can take many shapes and sizes, depending on the application. In a fixed inductor, the voltage and current, as well as the inductance value, remain constant. The LB3218T2R2M is an example of a fixed inductor.

The LB3218T2R2M is a High Current Low Profile 58 pc. SMT Fixed Inductor designed specifically for applications requiring high power. It has a form factor of 4.2mm x 8mm and a maximum current rating of 3A. It is assembled in a nickel-plated toproof package and has a saturated core material with a high permeability rating. It has a highly efficient design with low DC resistance and low EMI. It features very low ESR and ESL and is designed with low external parasitics.

The main application field of the LB3218T2R2M is in power battery management. It is primarily used for voltage and current transformation, such as smoothing DC voltage ripple in buck converters, and loop filters for power factor correction. It is also used in other applications including motor drive circuits and in any switch mode power supplies using DC-DC conversion.

The working principle of the LB3218T2R2M is based on Faraday’s Law of Induction. This law states that when a current (I) flowing through a conductor is changed, then an electric field (E) is produced, which induces a voltage (V). The LB3218T2R2M uses this principle to transform and filter voltage and current. When alternating current flows through the conductor, it causes an alternating magnetic field to be generated around the core. This induces an EMF in the windings, which in turn results in another alternating current. The inductance of the core is what defines the amount of EMF in the windings.

The LB3218T2R2M is designed for high power applications and is an optimal choice for battery management, motor drives, and DC-DC conversion. It provides high efficiency, low external parasitics, and low ESR/ESL, making it an ideal solution for a variety of power applications.
