Fixed inductors are inductive components that have fixed inductance and are connected in the circuit as passive elements. SC54B-121 is a type of fixed inductor, which designed to provide high inductance amounts in small size, mainly for power line applications. This article will mainly talk about its application field and working principle.

Application Field

SC54B-121 is widely used in the field of power process, especially for the applications of DC-DC converter output and expensive filter circuits. This component is designed to meet the requirements of high current electronic applications in power process, such as electronic load equipment, battery charger, motor, or other charge and discharge devices. Its wide application range makes it highly acceptable by majority of manufacturers.

Working Principle

The working principle of fixed inductors lies on the structure of its parts. It consists of a core material, a coil conductor, and a winding material. Firstly, the core material will act as a loop to pass on the magnetic field when the conductor coils around it. Secondly, when the current flows through the winding material, it can generate the both inductive and resistive force, which will help to maintain the circuit and provide power charging current. Lastly, the combination of the above functions will make the fixed inductor able to provide smooth power and provide necessary inductance for the power process safely and efficiently.

To conclude, SC54B-121 is a type of fixed inductor which is mainly designed for power line applications. It is widely used in DC-DC converter output and expensive filter circuits due to its high current and small size. It works by the help of its parts, such as core material, winding material and conductor coils, which help to pass on the magnetic field, generate the inductive and resistive force, and maintain the circuit respectively.
