Introduction
The SC105B-390 is a special type of fixed inductor that is widely used in many modern electronic applications. This specific type of inductor is composed of a coil of fine copper wire wound around a magnetic core, usually consisting of a ferrite or iron. The properties of the inductor are determined by the size, shape, material and type of the core, as well as the size and properties of the wire used.Application Fields
The SC105B-390 fixed inductor can be used in a variety of applications, ranging from power supply components to communication equipment, automobile electronics and even military equipment. It is most commonly used for power filtering, energy storage and current conversion. It is also used for regulation, voltage control, and power supply protection. The SC105B-390 is especially ideal for application fields that require low power consumption, low noise, low ripple and high efficiency. As a result, it can be found in applications such as switching power supplies, RF amplifiers, electronic ballasts, cell phones and other power supply components.Working Principle
A fixed inductor works by generating an electromagnetic field inside the inductor\'s core which absorbs energy from an electrical circuit. When the flow of electrical current through the inductor is increased, the electromagnetic field becomes stronger, resulting in an increase in electric energy. Likewise, when the current is reduced, the field becomes weaker and electric energy is released.This electric energy stored in the inductor\'s core can then be used to supplement the current or voltage of the electrical circuit as needed. As a result, the SC105B-390 can help to regulate the power supply by providing more or less current or voltage as required.Conclusion
The SC105B-390 fixed inductor is a versatile and highly efficient device used for power supply protection, current conversion and regulation, voltage control and many other tasks. Its properties are determined by the size, shape, material and type of the core, and the size and properties of the wire used, allowing it to be tailored for applications that require low noise, low ripple and low power consumption. Understanding the principles of how a fixed inductor works is essential to ensuring that it is used properly and performs its functions to the highest possible standards.
