Fixed inductors, whether attached or individually to electrical circuits, are designed to increase a current\'s power in a specific direction and at a specific voltage rating. The 4379-472HS can provide high power within the relatively low current range, making it well suited for use in a variety of applications, from automotive to industrial. This article will discuss the 4379-472HS\' application field and working principle.

Applications of 4379-472HS

The 4379-472HS is defined as a non-coring inductor designed to handle up to 10A of current. Its wide operating temperature range of -40°C to +85°C makes it suitable for use in multiple automotive, industrial, and commercial applications, including:

• Automotive power management systems
• Current-limiting circuits, such as UV feedback circuits
• Bulk storage capacitors
• Marker and lighting systems
• DC-DC converters
• Inductive heating applications
• Photovoltaic (PV) systems
• Voltage regulation and control systems

Additionally, the 4379-472HS is designed to support both the buck (increasing the voltage drop) and boost (increasing the voltage) functions of power management. The inductor can also be used with inductive heating and other power electronic systems for both commercial and industrial purposes. Its low DCR (direct current resistance), between 0.33 and 1.45 ohms, further increases its versatility.

Working Principle

The 4379-472HS uses magnetic cores to control current in a specific direction. This type of inductor has two coils, with one coil wrapped around the other to create an electromagnetic field. When current is applied to the coil, an inductance is created, blocking the flow of AC current in the circuit while allowing DC current to flow.

The inductor\'s magnetic cores use alternating current (AC) and direct current (DC) to induce a voltage at its terminals, built up gradually as it stores the current in its coils. This stabilizing effect can be used to reduce the voltage of components in a circuit, as well as to regulate the current and store energy. The use of the inductor\'s magnetic core also enables improved noise reduction, radiated emissions, and improved efficiency.

The inductor\'s internal components are also designed to react quickly to changes in current, allowing the 4379-472HS to effectively respond to light load or peak conditions and prevent over-current and other power-related events. This efficient response provides layer insulation, allowing the inductor to maintain its working temperature even in the most severe environments.

Conclusion

The 4379-472HS is a fixed inductor with a wide operating temperature range and a low DCR, making it suitable for use in a range of applications, from automotive to industrial. Its magnetic cores are designed to allow current in a specific direction, while its internal components are capable of quickly responding to changes in current and maintaining layer insulation even in extreme environments. The 4379-472HS is a powerful and reliable component for any current-limiter circuit.
