Fixed inductors are components used in electrical and electronic circuits, typically used to provide inductance and store energy in the form of magnetic fields. One such inductor is the PM125SH-271M. This inductor has a most common application field, as well as a working principle that makes it invaluable in many electrical and electronic applications.

Application Field

The PM125SH-271M inductor is used most commonly in power supplies. Many power supplies use inductors to both increase voltage and decrease ripple in outputs. Adjustable power supplies use these inductors by connecting them in series with dc-voltage sources. Inductors are typically also used in integrated circuits to help stabilize the voltages produced by the components of the circuit, often referred to as the “power rail”. Furthermore, this inductor can be used in assembling converters, amongst other current controlling components, such as voltage regulators and switches.

Working Principle

The PM125SH-271M inductor works mainly by inductive reactance and resistance. Inductive reactance is the opposition of an inductor to an alternating current, and this equals the product of the inductance and the frequency of the current. It can also be expressed as ‘Xₗ’. Resistance is the opposition of a conductor to the flow of electric current. It is measured in Ohms, and is represented by ‘R’.

The working principle of the PM125SH-271M involves both the inductive reactance and resistance. This relationship is described by the equation ‘Xₗ = 2πfL’, where ‘f’ is the frequency of the current. Thus, when the frequency is increased, the inductive reactance also increases. This is the main principle by which the PM125SH-271M works.

The PM125SH-271M also works utilizing the principles of self-inductance and mutual inductance. Self-inductance is the production of an induced current in the same circuit or loop, while mutual inductance is the production of an induced current in a second circuit or loop.

Another working principle of the PM125SH-271M involves the magnetic field produced by the inductor. This is what allows the inductor to store energy and convert it into electrical current. The more current the inductor is carrying, the more changing magnetic field is produced. This a result of the Faraday’s Law of induction, which states that the amount of voltage induced in a coil of wire is proportional to the change of the magnetic flux in time.

All of these principles allow the PM125SH-271M to have a wide range of applications in power supplies and integrated circuits. Without them, many of the processes described above would not be possible.
