Fixed Inductors are components designed to create a fixed amount of inductance in an electrical circuit. In general, the inductance of a fixed inductor is set in the manufacturing process, and cannot be adjusted. 4554-1R5K is a type of fixed inductor, with a well-defined application field and working principle. The 4554-1R5K is mainly designed for piezoelectric transformers and high voltage filters used for high-frequency AC power factor corrections. As its name implies, the component provides a fixed inductance of 1.5K ohms.The working principle of the 4554-1R5K is based on its physical structure. It consists of a thin copper wire wound around a ferrite core. The ferrite core is cylindrical in shape, with a hole in the middle. When an electric current passes through the thin copper wire, it induces a magnetic field around the core. This magnetic field creates a constant magnetic flux within the core, which in turn creates a varying magnetic flux around the core. This varying magnetic flux induces an electromotive force in the thin copper wire, which is proportional to the applied electric current. This electromotive force generates an Alternating Current (AC) that creates an alternating magnetic field around the core.This varying magnetic field induces a voltage in the core, which is proportional to the applied electric current. The voltage created in the core is then converted into a steady electric current by a transformer coil placed around the core. This steady electric current is finally used for power factor correction.4554-1R5K components have a wide range of applications in high-frequency AC power factor corrections, due to their ability to provide a steady electric current. The component is also widely used for ac power filter circuits, audio amplifier, and switching power supplies. The component is also used in computer and telecom systems, as well as for measuring steady currents. In conclusion, the 4554-1R5K fixed inductor is a compact and reliable component designed to provide a fixed amount of inductance in electrical circuits. It has a specific application field and working principle, used primarily for high-frequency AC power factor correction and other related purposes.
