Fixed inductors, sometimes referred to as "choke coils," are basic electronic components that are composed of an inductive coil that is wound around an air core, a metal core, or a ferrite core. The 103-332HS is an example of a fixed inductor and is typically used in signal-filtering applications, oscillator circuits, and local-area-network (LAN) applications. It is also found in control circuits, timing circuits, and power supplies.

Generally speaking, a fixed inductor introduces a source of inductance to a circuit. Inductance is an electrical property that helps control the flow of electric currents in connected circuits. Usually, fixed inductors have an inductance value noted in the unit “henries” and a rated current. The 103-332HS inductor is rated at 2.2µH and can handle 200mA.

The properties of a fixed inductor depend upon the inductor’s construction. This shape and size are determined by the application, such as which mounting style is used, power rating, and frequency rating. The inductor’s size and shape also affect the saturation current, which is the current required to cause saturation of the core material. It also affects the inductor’s self-resonant frequency, which affects the frequency response of the inductor’s energy storage. Smaller inductors often have higher self-resonant frequencies.

Fixed inductors have a wide range of applications, which includes trying to decrease and control the amount of current in a circuit, and they can even isolate signals from different frequency bands. This makes fixed inductors a suitable choice for signal filtering and controlling the amount of current draw in a circuit, as well as providing energy-storing capabilities.

The main components of the 103-332HS inductor are mostly the core material and the winding wire. A core material can be composed of air, metal, ferrite, or even a powdered metal alloy. The alloy core material is often constructed of non-magnetic silicon steel and is fitted into a cylindrical holder. The winding wire is wound around the core material and composed of several turns of wire. The number of turns depends on the manufacturer and the inductance of the inductor.

The mechanism of a fixed inductor and how it works is based on the principles of electromagnetic induction. Whenever an alternating current is passed through a winding of wire, the current’s changing magnetic field induces a voltage across said winding. This induced voltage produces a magnetic field in the core, and the interaction of the winding’s induced voltage and the core’s magnetic field creates an additional electrical current in the winding. Therefore, an induced voltage appears across the winding with an opposite voltage polarity of the primary voltage.

By understanding the working principle of the fixed inductor, circuit designers can make more informed decisions on the correct type and size of fixed inductor to use for their designs. The 103-332HS fixed inductor is an effective signal filter and suits many wide-range filtering applications. Its small size and its ability to handle high currents make it an excellent choice for any circuit designer’s components list.
