Fixed inductors are a type of electronic component typically used in electronic circuits to produce an electromagnetic field. A fixed inductor, such as the PG0426.681NL, is one of the most popular types of inductors. It consists of a core of made of ferrite or iron powder surrounded by copper windings, and is capable of storing energy within its electromagnetic field. This energy is then used to perform inductive AC to DC conversion, act as a filter, or to couple an AC signal from one stage to another.

Fixed inductors are typically used in AC to DC conversion, in which an alternating current (AC) signal is rectified to a direct current (DC), as well as in power supplies, filters, oscillators, and signal switching applications. In AC to DC conversion, energy from an AC signal is stored in a fixed inductor’s electromagnetic field, which then flows in a unidirectional manner, creating a DC signal.

The PG0426.681NL is a fixed inductor with a nominal inductance of 4.26uH and a maximum inductance of 5.27uH. It has a Q factor of 7.9 and a saturated core which helps provide higher power and saturation current. It also has a wide range of operating temperatures from -60°C to +125°C. The PG0426.681NL is typically used in converters, switch-mode power supplies, notebook chargers, and other applications that require intense power or high current.

The working principle of a fixed inductor is based on the concept of magnetic induction. In magnetic induction, when a changing magnetic field is passed through a circuit, an electromotive force (EMF) is induced in that circuit. In the PG0426.681NL, the magnetic field is generated by an AC signal, and as the electrons flow through the inductor, a magnetic field is generated inside the core which in turn induces an EMF in the windings of the inductor.

Fixed inductors, such as the PG0426.681NL, are able to store the energy from the electromagnetic field. This energy can then be used to create a unidirectional current flow, generate filtering effects in a circuit, or provide signal coupling between stages. This makes them an essential component in many electrical and electronic circuits.
