Introduction
A fixed inductor is a type of coil that stores energy within its core inductance when an electric current flows through it. The SC3308F-470 is a fixed inductor that can be used in a variety of applications. This article will explain the application field and working principle of the SC3308F-470.Applications
The SC3308F-470 is widely used for a variety of applications, such as power supply designs, EMI filters, RF circuits, and switching power supplies. The SC3308F-470 is designed with a 470uH inductance and a high saturation current of 37.5A, which makes it ideal for applications requiring high power and efficiency. Additionally, it has a lowcore loss and excellent thermal stability, increasing its performance and reliability.SC3308F-470 is also found in portable and wearable devices, such as laptops, tablets, and mobile phones. The low-profile design and robust insulation of the SC3308F-470 make it suitable for these high-density applications. It can reduce board space and improve signal integrity while providing high system performance.Working Principle
When an electric current flows through the winding of the inductor, an increasing magnetic field is produced that causes a voltage to be induced in the winding. This voltage is opposing the current and is called the counter-electromotive force (CEMF). The magnitude of the voltage is proportional to the rate of change of the current.The CEMF ensures that the current through the winding remains constant regardless of system power level. As the flux density in the core increases, the opposing CEMF increases, limiting the current to a predetermined level. This process is called inductive saturation.The core of an inductor is designed to limit the amount of flux that passes through the core. This property plays an essential role in controlling and stabilizing the current within the system.Conclusion
The SC3308F-470 is a fixed inductor that is used widely in a variety of applications, such as power supply designs, EMI filters, RF circuits, and switching power supplies. Its high saturation current, low-profile design, and robust insulation make it ideal for high-density applications. The inductor works by creating a CEMF that limits the current in the system, as well as controlling and stabilizing the power throughout the system.
