Fixed Inductors: SCPH73-471 Application Field and Working Principle

A fixed inductor, also known as a coil, choke, or reactor, is an electrical component that resists changes in electric current. Fixed inductors are widely used in a variety of electrical circuits, such as in high-frequency power delivery, voltage regulation, and noise reduction. Inductors are also essential components used in the manufacture of transformers.

The SCPH73-471 is one of the more common fixed inductors. First released in 2002, this component is used in various types of electronic circuits and equipment. It has a high inductance, making it suitable for use in the voltage regulation and motor control applications. The SCPH73-471 is also used in telecom applications, including base station power supplies, home networks, and Wi-Fi routers. It is also a commonly used component in high-frequency switch mode power supplies.

The SCPH73-471 is a leaded, 4-pin surface-mount component measuring just 8.0mm by 5.0mm by 2.0mm. It is designed for operation in temperatures ranging between -55°C and +125°C which supports its use in many telecom, automotive, and aerospace applications. The component utilises a 4-pin design which aids in heat dissipation and static shielding.

The operating field of the SCPH73-471 involves more than just temperature. The component also has an output current rating and impedance parameters to which it must conform in order to produce a safe and effective performance. The rated output current of the SCPH73-471 is 3A, and its impedance range is approximately 1-2mOhm. The component is designed to operate at frequencies between 4.2MHz and 39.5MHz.

The SCPH73-471 fixed inductor has two distinct operating principles. Firstly, it functions through inductive reactance which is controlled by the size of the component’s voltage induced or induced current. This principle refers to the amount of electrical energy that the component can store and release in alternating formats. Secondly, the SCPH73-471’s impedance is affected by its frequency. The inductors’ resistance to the AC signals is determined by its operating frequency. At higher frequencies, the component exhibits increased impedance.

Fixed inductors like the SCPH73-471 are used to guide and control electrical signals in AC circuits. This component has been used extensively since its introduction and its output current rating, impedance, and temperature range makes it suitable for a variety of applications. The SCPH73-471 is a highly compact yet reliable component that is easy to install and maintain.
