Fixed Inductors
Inductors are a vital component in a variety of electronics and electrical systems, providing an important function of storing and releasing energy in an electrical circuit. Fixed inductors are a subclass of components, distinguished from variable inductors by the fact that the inductance of a fixed inductor does not depend on any external operating parameter.The SP1210R-472K Fixed Inductor is a power inductor that is commonly used in DC-DC converters, along with other power supplies and filter circuits. The SP1210R-472K series utilizes high-energy powder cores for greater inductance output and low DC resistance, while its compact size is designed to occupy minimal board space.This article provides a brief overview of the SP1210R-472K series Fixed Inductors and their application fields and working principles.Applications
The SP1210R-472K is designed for use in high current applications, such as:- DC-DC converters
- Filtering Circuits
- Power supplies
- Intermu-powered circuits
- Computer peripherals
- Transmission equipment
Working Principle
The basic working principle of the SP1210R-472K Fixed Inductor is to store energy in a coil formed by insulated wire. As a current passes through the coil it produces a magnetic field, and the energy stored in the field is proportional to the inductance. This energy is then released whenever a change of current is observed, making the SP1210R-472K an ideal component for controlling steady state currents.The SP1210R-472K boasts a low DC resistance, high saturation current, high saturation inductance, and low DC impedance which makes it well suited for high current applications. Additionally, the SP1210R-472K\'s small size enables it to be integrated into power converters that have limited space for inductors.Conclusion
The SP1210R-472K Fixed Inductor is an essential component for a variety of applications, from filtering circuits to DC-DC converters. It is designed for high current applications, thanks to its low DC resistance, high saturation current, and high saturation inductance. Plus, it is able to maintain high accuracies and frequencies over a well-defined range and takes up minimal board space with its compact size.The specific data is subject to PDF, and the above content is for reference
