Fixed inductors are electronic components that are designed to store electrical energy in the form of electromagnetic fields when electrical current passes through them. They are used in many different types of applications, including power supplies, filters, audio and video amplifiers, and electronic timers. The SCRH104-390 is a type of fixed inductor that is designed specifically for use in open-frame switching power supplies and can also be used in other applications that require high-current handling capability. This article will discuss the application field and working principle of the SCRH104-390.

Applications of the SCRH104-390
The SCRH104-390 is primarily used in open-frame switching power supplies that are used in the telecommunications, computer, industrial automation, and consumer electronic markets. These supplies require the use of reliable inductors that can operate in a wide range of temperatures. The SCRH104-390 is designed to meet the high-frequency switching demands of power supplies and the wide temperature range requirements of the application. The main application areas for the SCRH104-390 are DC/DC converters, switch-mode power supplies, industrial automation circuits, LED lighting, and motor drives.

Working Principle of the SCRH104-390
The SCRH104-390 is a type of coreless, fixed inductor that uses a metal core to store electrical energy. It is designed to operate in temperatures from -40 to +125 degrees Celsius. The inductor is constructed with a ferrite core and a winding of copper wire. It is encapsulated in an epoxy material for protection from vibration and shock. The inductor operates by inducing an electromagnetic field when a current is applied. The current flows through the inductor and the metal core stores the energy in the form of an electromagnetic field. This field can then be used to power the circuit when the current is removed.

The SCRH104-390 has a high saturation current rating and low DCR that make it ideal for use in high-frequency switching applications. The inductor is designed to operate at frequencies of up to 400kHz and has a maximum rated current of 5A. The low DCR of the inductor means that it can be used to provide high-power levels with minimal energy loss. This makes it especially useful for applications such as motor drives, LED lighting, and DC/DC power conversion.

Conclusion
The SCRH104-390 fixed inductor is designed for use in open-frame switching power supplies and other applications that require high-current handling capability. It is constructed with a ferrite core and a winding of copper wire, and is designed to operate in temperatures from -40 to +125 degrees Celsius. The inductor has a high saturation current rating and low DCR that make it ideal for use in high-frequency switching applications. This makes the SCRH104-390 an ideal choice for applications such as DC/DC power conversion, switch-mode power supplies, industrial automation circuits, LED lighting, and motor drives.
