Introduction

Fixed inductors are electrical components made of a wire or coil which stores electrical energy when an electric current flows through it. These components can have either a unidirectional or bidirectional effect, depending on the specific application. The S1210R-392K is a particular type of fixed inductor manufactured by A-Star Technology Co. Ltd. This inductor is designed for use in high-current/high-voltage applications, such as power supplies and other power applications.

Application Field

The S1210R-392K fixed inductor is designed to be used in high-current and high-voltage power applications. These kinds of applications typically require components with robust and reliable performance characteristics. The S1210R-392K meets this criteria, as it can safely handle current up to 16A and voltage up to 420V. Additionally, the S1210R-392K has been designed with a high saturation current rating, which ensures the component can easily handle the expected surge currents associated with certain projects.The S1210R-392K also offers excellent thermal shock protection, meaning it can be easily used in safety-critical projects that require a high level of reliability. Furthermore, this inductor has a wide operating temperature range and is designed to withstand significant levels of shock and vibration. This makes it perfect for automotive and aerospace applications.

Working Principle

The S1210R-392K works on the principle of an inductor. An inductor consists of a current carrying wire or coil, which is usually wound around a core material such as a ferrite or steel. When current flow is passed through the coil, it generates a magnetic field which induces an opposing voltage into the coil. This opposing voltage is known as an inductive reactance, and it helps to limit the flow of current through the inductor.This limiting of current flow helps to protect the component from overloading due to excess current. Furthermore, it can also help to reduce ripple noise in audio applications. This is particularly useful when the component is used in an environment where noise suppression is needed.

Conclusion

The S1210R-392K fixed inductor is designed for high-current/high-voltage power applications, such as power supplies and other power applications. It is capable of handling current up to 16A and voltage up to 420V, making it ideal for safety-critical projects. This inductor also offers excellent thermal shock protection, a wide operating temperature range, and improved shock and vibration ratings. The S1210R-392K works on the principle of an inductor, where opposing voltage is generated by the flow of current through a wire or coil wound around a core material. This feature helps to reduce ripple noise and protect the component from overloading.
