Fixed inductors refer to inductors with a fixed inductance and a layer of insulating material coated on the winding. They are passive components used to store energy in electric fields. One of the most commonly used fixed inductors is the LBC3225T220MR. This article will explore the application field and working principle of the LBC3225T220MR.

The LBC3225T220MR is a type of surface mount power inductor, which is widely used in various industrial appliances, especially in automotive applications. Its features include an inductance range of 0.22 μH to 100 μH, current rating of 28A to 100A, andDC resistance range of 0.01 ohm to 0.3 ohm. In addition, the inductor has a high saturation current of up to 1.5 times the nominal current.

In terms of application, the LBC3225T220MR is most commonly used in power supply circuits, such as switch mode power supplies (SMPS) and DC-DC converters, where it can store energy temporarily, filter high frequency noise and reduce ripple voltage. In audio power amplifiers, they can also reduce the distortion of the output signal. Moreover, it can also be applied in automotive applications as it is resistant to high temperatures, vibration and shock.

The working principle of the LBC3225T220MR is based on the basic laws of electromagnetism. When an alternating current (AC) passes through the inductor’s winding, it generates an electromagnetic field that induces an electromotive force (EMF) in the winding, thus creating a back EMF. This back EMF opposes the flow of current in the inductor, reducing the current and resulting in a voltage drop across the inductor.

Aside from this, the LBC3225T220MR also exhibited several properties related to its inductance that can be affected by a variety of external factors. Firstly, inducer will be affected by different operating frequencies. The amount of current that can pass through the winding will depend on the frequency of the alternating current applied to the inductor. Moreover, the core material used in the construction of the inductor will also affect the values of inductance and current as different materials have different magnetic permeability.

In conclusion, the LBC3225T220MR is a type of surface mount power inductor that is widely used in various industrial applications. Its most common application fields include power supply circuits, audio power amplifiers and automotive industry. Its working principle is based on the basic laws of electromagnetism, and the values of inductance and current can be affected by a variety of external factors.
