Introduction to Fixed InductorsA fixed inductor is an electrical device that stores energy in an inductive coil fields. It is a component used in electrical circuits to pass electric current in one electrical direction. Typically, the inductor is made up of a coil of insulated electrical wire formed around a ferromagnetic core. When an electric current passes through the coils, a magnetic field is generated and stored in the component. Fixed inductors are used in a variety of electronics including radios, televisions, computers, and amplifiers. MS90538-12ST Application FieldThe MS90538-12ST fixed inductor is a high current coil manufactured by Ideal Industries. It is designed for use in high power switching circuits, power factor correction circuits, and other applications that require high current through the inductor. The inductor can handle an impedance up to 610Ω and a direct current rating of 3 A. The inductor has a 32 mm diameter, an 18-hole body, and a maximum pull-up feature of 1-2A. Its temperature range is -25 to +155 degrees Celsius. Its rectangular shape enables the inductor to be mounted in an enclosure and used in limited-space power circuits. MS90538-12ST Working PrincipleThe working principle of the MS90538-12ST fixed inductor is based on Faraday’s law of induction. When an electrical current is passed through the inductor coils, a magnetic field is generated and stored in the component. This process of inducing an electrical current from a magnetic field is known as induction. The stored magnetic field in the component then acts as a magnetic field that produces a reaction when exposed to a changing magnetic field. This reaction is known as inductance. Inductance is the ratio of the magnetic flux linking with the inductor coils to the current flowing through the cable. The greater the inductance, the higher the voltage produced by the inductor. The MS90538-12ST fixed inductor is designed for high current values and can store an impressive amount of electrical energy. The high current values are achieved by the inductor’s ability to induce a higher voltage as the current passing through it increases. The inductor’s rectangular shape also enables it to produce higher voltages, as it allows for a greater number of turns in the inductor’s winding. The increased number of turns increases the magnetic flux generated and increases the inductance of the inductor. ConclusionThe MS90538-12ST fixed inductor is a valuable component used in high-power electrical circuits. Its increased current rating, rectangular shape, and high current handling capacity make it suitable for applications such as high-power switching circuits, power factor correction circuits and more. Its working principle is based on Faraday’s law of induction, in which an electric current is induced from a changing magnetic field. The inductor’s rectangular shape enables it to store higher electrical energy, as more turns in the winding create a higher inductance.
