Fixed Inductors

Inductors are one of the most important components of electrical networks since they are used as energy-storing elements, providing an effective regulation of current flow in certain circuits. The application of fixed inductors is wide-ranging, from the simplest AC circuits to complex computer applications. One of the most popular types of fixed inductors is MLF2012DR27MT, which is an SMD chip, allowing for a compact size and high performance.

MLF2012DR27MT Application Field

MLF2012DR27MT fixed inductors are mostly used in medium-power AC circuits. This type of inductor is used mainly to filter out and reject unwanted noise and variations in the current flow. It is also used in switching power converters, battery chargers, rectifiers, DC-DC converters, RF-DC converters, radio transmitters, and automotive applications.

MLF2012DR27MT Working Principle

The MLF2012DR27MT fixed inductor basically works in the same way as any other inductor. It converts the flux of the electric current into a force and, in doing so, produces inductive reactance, discussed in detail below. When an alternating electric current is applied to the inductor, the current flows in one direction, then reverses. This change in current flow results in the production of an alternating magnetic field. The magnetic lines of flux produced by the current through the inductor loop penetrate the coil and convert the current into force. By the property of inductance, the MLF2012DR27MT inductor limits the current flow rate to a predefined value. As the current/voltage passes through the inductor, the inductor stores the current in a magnetic field and its energy is equal to the power dissipated in the inductance. As a result, the inductors not only provides a more steady and constant current, but also generates a controlled amount of current flow.

Conclusion

The MLF2012DR27MT fixed inductors are widely used in many medium-power AC circuits due to its various features such as high performance, low size and efficiency. The principle of operation of this fixed inductor, which consists of converting the electric current flux into a force and creating an inductive reactance, is quite simple but provides an effective regulation of current flow in certain circuits.
