Fixed inductors are passive components, commonly called coils, which are used to oppose the change of current in a circuit. Inductors are used in a variety of circuit applications, from radio frequency signal filtering to voltage regulation and control systems. The SP1008R-472H is an example of a fixed inductor typically used in low-noise, high-frequency applications.

The SP1008R-472H is an axial leaded inductor with an inductance of 4.7 uH and a rated current of 1.05A. It is constructed using six cores of wound copper wire bound in a thin plastic shell. This inductor has excellent thermal stability and excellent outgassing properties which make it suitable for space and aerospace applications. The design also improves efficiency when using the inductor in video, RF and other power circuitry, as it reduces power consumption by up to 1/3rd.

The SP1008R-472H\'s application field includes frequency filtering, oscillator circuits, switching power supplies, switching regulators, and voltage converters. It is a good choice for low-noise RF amplifiers, due to its consistent inductance and high-frequency characteristics.

The working principle of the SP1008R-472H is straightforward. When a direct current passes through the inductor, a magnetic field is created around the inductor. This magnetic field then opposes the change of the current. This is known as inductance, and it can be used to increase or reduce the flow of current in a circuit. This is especially useful in frequency filtering, where it is used to reduce the high frequency noise in a signal by opposing the changing current.

The SP1008R-472H has a wide range of applications and is generally regarded as an excellent choice for low-noise, high-frequency filtering and control systems. It is designed with excellent thermal stability and excellent outgassing properties, making it suitable for aerospace and space-related applications. The efficient design of this inductor means that it also helps reduce power consumption when used in video, RF, and other power circuitry.
