Fixed inductors are electromechanical devices, sometimes known as coils, that are used to store electrical energy while reducing the amount of ac current in an electrical circuit. They are used in a wide range of applications including radio transmitters and receivers, audio equipment, electronic control systems and telecommunications. Fixed inductors have two basic parts; the core and the winding. The core is made up of ferromagnetic material while the winding is typically made of a conductive material such as copper. The core is magnetized by current flowing through the windings via a process called inductance. A flux field is produced in the core which essentially stores the electrical energy in the form of a magnetic field.

PM1008S-2R7M-RC is one example of a fixed inductor. It is a shielded, ferrite core inductor, with a maximum DC current rating of 7 Amps and an inductance of 2.7mH. It is typically used in high frequency power circuits, such as power amplifiers, power supply circuits, and switch mode power supplies. It is designed to reduce unwanted noise and line interference, and also to reduce the “ringing” of switching devices. PM1008S-2R7M-RC is a surface mount capacitor (SMT) and is typically used in high density applications. It is also a compact size, with overall dimensions of just 14.6mmx9.6mmx6.5mm.

The working principle of a fixed inductor is based on the principle of induction. This is an electromagnetic phenomenon where a conductor such as a wire or coil in a magnetic field, produces a voltage in the conductor proportional to the rate of change of the magnetic field in relation to the conductor. When a current passes through a fixed inductor, a stationary magnetic flux field is created in the core of the inductor. This magnetic flux is then increased or decreased when the current flowing through the inductor changes.

The amount of voltage induced in the coil is directly proportional to the number of turns in the coil, the rate of change of the flux, and the type of material used in the core. By increasing the amount of turns in the coil, with the same rate of change of flux and core material – the inductor produces a larger amount of voltage than is present before the current is applied. This voltage can then be used to control the flow of current in a circuit. This change in voltage, due to the changing of the magnetic flux field, is the basis of how a fixed inductor works.

In addition to producing a voltage proportional to the rate of change of the magnetic field in relation to the conductor, fixed inductors can also have a self-resonant frequency. This is the frequency at which the inductor begins to resonate and oscillate freely. This oscillation is caused by the electromagnetic waves produced by the inductor, as it stores energy in the form of a magnetic field. This frequency should be above the frequency of the signal passing through the inductor for it to function properly. This helps to reduce the amount of noise on the signal and can help to increase the reliability of the circuit in which it is used.

PM1008S-2R7M-RC fixed inductors are used in a variety of applications for the purposes of power management. They are most often used in high frequency power circuits, such as power amplifiers, power supplies, and switch mode power supplies. They are designed to reduce noise and line interference, as well as reduce the “ringing” of switching devices. They are a reliable and effective component for the purpose of power management, and are a great choice when selecting a fixed inductor for your application.
