Fixed inductors are typically used in electronic circuits to temporarily store energy in the form of a magnetic field created by the current running through them. The 4379-106KS fixed inductor is a part of Vishay Dale\'s family of Power Inductors, and is specifically designed for use in DC-DC converter applications.

Features

The 4379-106KS Power Inductor has a variety of features that make it versatile enough for use in a wide range of DC-DC converter applications. Its shielded construction results in low magnetic flux leakage for increased signal integrity and less interference with other components. It also features a high-copper content core that increases efficiency, high rated current, low minimum coil production resistance, a ferrite core material offering excellent thermal stability, and lead-free construction.

Application Fields and Working Principle

The 4379-106KS is used in many different types of DC-DC converter applications. It can be used in basic DC-DC converters, synchronous rectification buck converters, automotive powertrain systems, multiple output switching regulators, and voltage multipliers. It also has a wide range of applications in automotive, medical, computing, communication, and consumer electronics.

The working principle of the 4379-106KS Power Inductor is based on Faraday\'s law of induction, which states that when a conductor moves through a magnetic field, an electric current is induced in the conductor. The circuit is made up of two coils: the primary coil, and the secondary coil. When a current is passed through the primary coil, a magnetic field is generated in the secondary coil, thus inducing an electric current in the secondary coil.

The 4379-106KS includes diodes to ensure current flow is in the correct direction and to keep the energy from flowing backwards. The inductor also has a capacitor connected in parallel to help store the energy generated by the inductor and reduce the voltage ripple of the output. The capacitor also helps to limit inrush current by providing a large capacitance that stores energy and prevents it from flowing back into the circuit.

Conclusion

The 4379-106KS Power Inductor is a versatile part that can be used in a wide range of DC-DC converter applications. Its shielded construction helps reduce magnetic flux leakage for increased signal integrity and reduced interference, and its high-copper content core provides increased efficiency and voltage control. Its Faraday induction-based working principle enables the inductor to efficiently store energy and reduce voltage ripple, while its diodes and parallel capacitor prevent backflow and limit inrush current. As such, the 4379-106KS is a highly-effective fixed inductor that can meet the demands of a variety of applications.
