Introduction
Fixed inductors are electronic components that store energy in the form of a magnetic field. They are used in many electronic applications ranging from power supplies to amplifier circuits. The SC30R18KT is one of the most popular models of fixed inductors in use today. This paper will discuss the application field and working principle of the SC30R18KT.Application Field
The SC30R18KT is commonly used in power factor correction, electronic filter, line compensation, resonant inductor, output rectifier, radio frequency interference suppression, and signal transformer applications. It is also used in many consumer electronics, such as cameras, televisions, and home audio systems. The SC30R18KT can handle current levels up to 30 amperes, and its maximum frequency is 100kHz.Working Principle
The SC30R18KT is composed of a core and two coils of wire wound around it. Whenever an electric current passes through the coil, a magnetic field is created in the core. This magnetic field stores energy, which is then released when the current decreases. The core of the SC30R18KT is composed of high quality ceramic material, which ensures that the AC current is passed through with minimal losses.The AC current passing through the SC30R18KT creates two alternating magnetic fields in the core. These fields interact, causing the current to create voltage. As the voltage reaches its maximum or minimum, the current decreases. This decrease in current causes the magnetic field to collapse and release its energy. This energy is transformed into output voltage.Conclusion
The SC30R18KT is a popular fixed inductor used in a variety of electronic applications. Its high quality ceramic core reduces losses, and ensures that it can handle high levels of current and high frequency operations. The SC30R18KT\'s working principle is based on the interaction of two alternating magnetic fields, which is used to create output voltage.
