Introduction to Fixed Inductors
Fixed inductors are used extensively in many different electronic circuits, especially those involved with high-frequency applications. To meet these various needs, inductors are rated either by their self-inductance (the amount of inductance coil coils generate when the current is constant) or by their inductive reactance (a measure of the inductor’s resistance to current flow at varying frequencies). The most common types of fixed inductors include air-core, ferrite-core, and toroidal inductors. In this article, we will focus on the MGA0502R47M-10 inductor and discuss its application field and working principles.

Application Field of the MGA0502R47M-10 Inductor
The MGA0502R47M-10 is a miniature, air-core inductor. It has a flat, horizontal top and a cylindrical base that measure 5.0mm x 2.0mm. The inductor has an Impedance of 0.47mH. It is lightweight and has low DCR with a maximum DC of 15A. It is hermetically sealed and is suitable for applications requiring ultra-low profile and space efficiency. This inductor is mainly used as power inductors in DC/DC converter, ADMV7, and circuit board applications. It is a common choice for power inductors for integrated circuits (ICs) and for power line filtering and regulation in switching power supply circuits. The use of this inductor significantly increases circuit efficiency and reduces the design effort for end-products as it can be used with other components without much modifications.

Working Principle of the MGA0502R47M-10 Inductor
An inductor functions through the use of two basic principles: electromagnetic induction and inductive reactance. Electromagnetic induction is a process in which a current flow generates a magnetic field around the inductor which is proportional to the current that flows through it. This magnetic field produces a current in a second circuit. The energized second circuit\'s current is the induced EMF, which works against the first circuit\'s current causing a decrease in the voltage. Inductive reactance is the opposition to current flow through an inductor and is expressed as a measure of the AC impedance of a coil. The resistance of the wire and the size of the inductor coil/core material used are factors that contribute to the capacitance. For the MGA0502R47M-10 inductor, its flat, cylindrical shape increases the surface area of the inductor, giving it more inductive reactance. This means that the inductor will be able to absorb more energy, allowing more voltage regulation, and, as a result, the inductor will capable of producing higher voltages regulate that are efficient.
In conclusion, the MGA0502R47M-10 is a miniature, air-core inductor that is mainly used as power inductors in DC/DC converter, ADMV7, and circuit board applications. Its flat, cylindrical shape provides it with more inductive reactance, allowing it to absorb more energy and produce higher voltages regulate with increased efficiency.
