Fixed inductors are a type of electronic component used in many electronic projects and they are most commonly classified according to the physical structure, application field or working principle. The particular type of fixed inductor in which this article will focus is known as the SWS-4.50-19. According to data provided by the manufacturer, this component has an inductance value of 4.50 μH and is rated to provide an inductive current of 19 A.

The construction of this particular fixed inductor is worth mentioning. It consists of an enclosure that is made of ferrite or air-cored and a coil of copper wire. The actual inductor is wound around a ferrite, air-cored or a core of other material; while the windings are usually composed of cotton paper. The SWS-4.50-19 fixed inductor is insulated from the external environment and is also quite durable due to the fact that the core material is very robust.

In terms of application, these components are ideal for power circuits that are used in various sectors such as aerospace, medical, automotive, communications and consumer electronics. The fixed inductors can also be used in converters, inverters, RF circuits and high-frequency switched-mode power supplies. Additionally, this type of inductor also serves as an EMI/RFI filter, as a voltage regulator and as an energy storage inductor. Due to its high inductance value, these components are well-suited for low-voltage applications where space is at a premium.

The working principle of this kind of inductor is based on the Faraday’s law of induction; which states that a change in magnetic flux produces an electric current in a circuit. The fixed inductor works on the same principle; when an alternating current is applied to the winding of the inductor, it creates a magnetic field that induces a voltage across the internal and external windings. This induced voltage produces a counter-EMF which opposes the original applied EMF. This phenomenon is known as inductive reactance, which is what this component is designed to offer.

In conclusion, the SWS-4.50-19 fixed inductor is a type of electronic component that is typically used in power circuits such as those that are found in aerospace, medical, automotive, communications and consumer electronics. The construction consists of an enclosure that is made of ferrite or air-cored and a coil of copper wire. The working principle is based on the Faraday’s law of induction, wherein an alternating current is applied to the winding of the inductor creating a magnetic field that induces a voltage across the internal and external windings, thus producing a counter-EMF.
