Fixed inductors, such as the AISC-1812H-101K-T, are electronic components that incorporate reactive elements like an inductor in order to provide an electrical path to discharge or store energy. They are made up of windings, or turns, of an electrical conductor, around a core of material, usually iron, that has a high permeability to ensure that more flux passes through the core than through the air surrounding it. This means that the circuit will draw less current than it normally would in order to get the same amount of inductance.

The AISC-1812H-101K-T is a surface-mounted fixed inductor which is designed to be one of the smallest size SMD inductors available. It is primarily used in power supply designs due to its very low DC current consumption, high impedance, and wide temperature range. It has been designed to work with up to 8A of direct current in storage capacitors with a very low ESR. Moreover, it can handle an AC load up to 25 A per cycle.

The electrical working principle of the AISC-1812H-101K-T is based on Faraday’s Law of Induction. This law states that a changing magnetic field will induce an EMF in a conductor. In this case, the magnetic field is produced by the current flowing through the windings of the inductor and it induces an EMF in the opposite direction to the current, thus creating a self-induced current, or counter-electromotive force, that is inversely proportional to the rate of change of the original current.

This counter-EMF opposes the direct current and this is why inductors are commonly referred to as devices that have "impedance" or "reactance". This is because it takes energy for the magnetic field to be created and for this field to oppose the original current, thus storing energy in the form of a field. The size of the resistance or reaction of the inductor depends on the number of turns of the conductor, as well as on the core material.

The AISC-1812H-101K-T is mainly used in applications where a large inductance is needed in a very small space, such as in power supplies or in medical devices. It can also be used as a filtering device, as the counter-EMF created blocks undesirable noise or ripple voltage. Furthermore, it can be used to limit the current in a circuit or as a resonant component in filters and oscillators.

Overall, the AISC-1812H-101K-T is an extremely small and powerful fixed inductor that can be used in a variety of power supply and other electrical applications. It has a wide temperature range and can handle high currents with minimal losses, making it a highly efficient and reliable component. It is based on Faraday’s Law of induction and uses magnetic fields to create and store energy, thus providing an effective way to limit current and filter noise.
