Fixed Inductors

Inductors are basic passive devices used to control electricity, store or release energy. They come in a variety of forms, sizes and types, each with its own specific application and purpose. Fixed inductors, or non-adjustable inductors, are a type of inductors that consist of a fixed coil, often made from a metal core or ferrite material. DFEH7030D-6R8M=P3 is one such type of fixed inductor. It is a three-pin-through-hole device that utilizes a dual-layer winding with a 6.8 μH inductance rating.

Application Field

The DFEH7030D-6R8M=P3 is designed to meet the demands of power supplies, EMI filter applications, DC-DC converters, and frequency control networks. It is also suited to various kinds of switching regulator circuits in technologies such as portable electronics, broadcasting systems, computers, and DC motors.

Working Principle

Fixed inductors work by creating a magnetic field in which a current of electrons can flow, as opposed to electric current that can only flow through metal conductors. As current passes through the inductor, it creates a magnetic field in the metal core. This field attracts a reaction current and resists the flow of current. As a result, the voltage drop across the inductor is proportionate to the current flowing through it.The DFEH7030D-6R8M=P3 features a dual-layer winding for increased current handling and improved thermal performance. The dual-layer windings ensure that the current being transferred is well distributed, allowing the inductor to operate safely and efficiently. The DFEH7030D-6R8M=P3 is also characterized by its high Q factor, which is the ratio between the inductance and the resistance of the inductor. This is important as it affects the efficiency of the inductor in converting electrical energy into a magnetic field. The higher the Q factor, the more efficient the inductor will be, and the more energy it can store within the magnetic field.

Materials and Construction

The construction of the DFEH7030D-6R8M=P3 is based on a dual-layer winding. The winding itself is made from copper wire which is then encapsulated in polyvinyl chloride (PVC) to protect the wire from the elements. The core is made from a ferrite material, which is a type of core material that is known for its high electrical resistance and low magnetic permeability. This combination of materials ensures high performance, as well as low losses in terms of power and energy.

Conclusion

The DFEH7030D-6R8M=P3 is a fixed inductor that has been designed for use in various power supply, EMI filter, DC-DC converter and frequency control networks. It features a dual-layer winding for increased current handling and improved thermal performance, as well as a high Q factor for maximum efficiency in converting electrical energy into a magnetic field. The materials used in its construction also make it durable and reliable in all types of applications.
