Fixed inductors have found a wide variety of applications in the electronics industry. The SC75B-390 is one example of a fixed inductor, and this article will discuss the application field and working principle of this product.

Application Field of the SC75B-390

The SC75B-390 is a surface mount fixed inductor. It is designed for low-voltage, low-frequency applications, and is typically used in a variety of frequency filtering applications such as smoothing circuits, filtering circuits for low frequency signals, and buck converters.

The SC75B-390 has a high current handling capacity and is designed for use in repetitive pulse operation. It is available in several different case sizes and diameters, which makes it ideal for a wide range of applications.

The SC75B-390 is also suitable for use in DC/DC converters, as it has low resistance and good stability. It is also suitable for use as a matching element in high frequency filter designs and in high frequency switching systems.

Working Principle of the SC75B-390

The working principle of the SC75B-390 is based on the principle of self-induction, or Faraday\'s Law of Induction. When an electrical current is flowing through a wire or component, a magnetic field is created around the wire or component. If the electrical current changes, either suddenly or gradually, then the magnetic field will also change. This changing magnetic field then induces an electrical current in the same wire or component, causing a self-induced voltage.

The SC75B-390 is designed to take advantage of this self-induction principle. When the current through the component changes, the magnetic field changes and the self-induced voltage is created. This self-induced voltage is then used to filter the current, either to reduce high frequency noise or to reduce low frequency ripple operation.

The SC75B-390 is also designed to be a low-resistance, low-loss component. This ensures that the output voltage is not affected by the resistance and loss of the component, which is important in ensuring efficient operation.

Conclusion

The SC75B-390 is a surface mount fixed inductor designed for low-voltage, low-frequency applications. It is ideal for frequency filtering applications such as smoothing circuits, filtering circuits for low frequency signals, and buck converters. Its working principle is based on the principle of self-induction, and it is designed to be a low-resistance, low-loss component to ensure efficient operation.
