Fixed inductors are electrical components, dedicated to resist a specific change in the electric power that passes the inductor. Different types of fixed inductors exist and offer a variety of implementing possibilities, ranging from simple electrolytic capacitor to complex ceramic immersed cores. The SP1812-154K fixed inductor is mainly used in the field of power electronics, researching and sensing analog signals.

The SP1812-154K is a fully shielded, non-polarized single-phase inductor, designed and manufactured to use at low operating frequencies. Its construction balances low impedance and excellent reliability in harsh environments. It is built with a metal encapsulated core and substrate, as well as a thick layer of an insulated coating that protects the core from short circuit.

The working principle behind a fixed inductor is based on Faraday\'s Law of Induction. According to it, when a voltage is applied across a conductor, a certain amount of electric current is induced in this conductor. The current flow produces a magnetic field, which induces a voltage in a second conductor. This second conductor is connected to the first conductor, forming a closed loop, and this entire loop acts as an inductor. The amount of voltage induced in the second conductor is proportional to the amount of current induced in the first conductor. This voltage is constant and has a specific magnitude, known as the "Magnetization Voltage" of the inductor.

The SP1812-154K is designed to resist a specific and adjustable magnetization voltage. It works by transferring the electrical and magnetic fields generated by the magnetization voltage. This process occurs through an electric current conduction that creates a compatible answer for a certain inductance. The SP1812-154K contains two toroidal cores; one of ferrite and the other of iron powder, both surrounded by a metal case. This allows a combination response of the currents generated by the magnetic fields of the two magnetic cores. This design gives the inductor its combined resistance to the magnetization current, which is adjustable according to the inductor\'s frequency.

In summary, the SP1812-154Kfixed inductor is an ideal solution for applications in power electronics, researching and sensing analog signals. Its construction and Faraday\'s Law-based technology provide an adjustable resistance to the magnetization voltage, depending on the inductor\'s frequency. It is safe, reliable and easy to install, making it a dependable and efficient component.
