Fixed Inductors

A fixed inductor is an electrical device that uses the principle of electromagnetic induction to store energy in the form of a magnetic field. In a typical inductor, a coil of wire is wound around a core material, such as ferrite or iron. When an electrical current flows through the wire, a magnetic field is created in the core material, which in turn induces a current in the wire. The magnitude of the induced current depends upon the inductance of the coil, which is determined by the number of turns of the wire and the size and type of core material.

A particular model of fixed inductor, the 78438356015, is designed for use in applications such as power supplies and switching circuits. As its name suggests, it is a fixed inductor, meaning that the amount of current it can produce is fixed at a specified level. Therefore, it is not suitable for applications which require an adjustable inductor. However, its fixed value of inductance makes it suitable for use in applications where a predictable level of current is desired.

The 78438356015 fixed inductor is designed to operate at relatively low frequencies, typically up to 500 kHz. Its low-cost construction and design, combined with its ability to hold its magnetic field in place, makes it very popular for many types of circuit applications. Its physical construction consists of a single coil of wire, approximately 1mm in diameter, wound around a cylindrical, ferrite core. A steel housing is then clamped firmly around the core, providing mechanical protection and stability for the inductor.

The basic working principle of the 78438356015 fixed inductor is quite simple. When an alternating current, or AC voltage, passes through it, an oscillating magnetic field is created around the inductor. This magnetic field induces a current in the wire, producing a voltage across it. The magnitude of the voltage is determined by the inductance of the inductor, as well as the frequency of the current. The higher frequencies will produce higher voltages across the inductor.

The 78438356015 fixed inductor is a popular choice for many power supply and switching circuits, due to its low-cost construction and its ability to store and release energy in the form of a magnetic field. Its wide range of frequencies, combined with its fixed inductance, make it well suited for applications where a fixed level of current is desired.
