Fixed inductors are one of the most important components in the electronic circuit and have a wide range of applications. One of the widely used fixed inductors is the SRR7045-2R2M. This article will discuss the application fields and working principle of SRR7045-2R2M.

SRR7045-2R2M is a molded, radial-leaded, 2.2 μH inductor with a saturated current rating of 1.15A. It is constructed with two separate windings with a gap between them. The inductor is multifunctional due to its combination of two separate windings and its high inductance. It can be used as a decoupling inductor, a common mode inductor, an RF inductor, a DC-DC converter inductor, and a magnetic shielding inductor.

The principle of the SRR7045-2R2M inductor is based on Faraday\'s law of electromagnetic induction, which states that a change in the magnetic flux through a circuit induces an electromotive force or voltage. When an electric current passes through the inductor\'s windings, a magnetic field is generated. This magnetic field causes a change in flux, which in turn induces an electromotive force or voltage in the second winding. The amount of voltage induced in the second winding is directly proportional to the change in flux, which is in turn proportional to the current flowing through the inductor.

The SRR7045-2R2M is a popular inductor for wide range of applications including power management, voltage regulation, EMI suppression, and RF amplification. It can be used as a decoupling inductor in DC-DC and SMPS power conversion circuits. It can be used to reduce noise in high frequency switching circuits. The inductor\'s high inductance and low DCR make it suitable for RF-amplifier applications. It can also be used in magnetic shielded boxes for EMI suppression.

In summary, the SRR7045-2R2M is a popular fixed inductor with multiple application fields ranging from power management to EMI suppression. It works based on Faraday’s law of electromagnetic induction, by generating a magnetic field in response to an electric current and inducing a voltage in a second winding based on the change in the flux.
