Fixed inductors, also known as chokes, are electrical components that have coils of wire wrapped around a core, usually Iron. They are used to store and control the flow of electricity in an electrical circuit. DFE252012F-6R8M=P2 is a type of fixed inductor which has been designed for use in a variety of applications.

Design Specifications

The DFE252012F-6R8M=P2 fixed inductor has a shielded construction in a 2520 size package. Its key specifications are as follows:

• DC Resistance: 6.8 mΩ ±20%
• Inductance: 2.0 mH ±15%
• Operating current: up to 0.9A
• Saturation current: up to 5.4A
• Frequency range: up to 10MHz

Application Field

The DFE252012F-6R8M=P2 fixed inductor is typically used to suppress noise or ripple in electronic circuits. It is also widely used to filter the output signal from digital or radio frequency switching power supplies. It is capable of suppressing frequencies up to 10MHz and more, so it is an ideal filter for noise suppression in certain RF applications, such as satellite TV receivers or cell phone base stations.

It is also suitable for applications such as high-current DC-DC converters and various motor control circuits. The inductor is designed to resist high temperatures and provide reliable performance even in harsh environments.

Working Principle

Fixed inductors work according to the principle of magnetic fields and electrongy. When an electric current passes through a wire, it creates a magnetic field which expands outward from the wire in a circular pattern. When another wire is positioned in the same magnetic field, it experiences a force from the field. This force is known as inductance, and is proportional to the current. By controlling the size and shape of the wire and its location within the magnetic field, the inductance of the fixed inductor can be precisely defined.

When the inductor is connected in a circuit, the inductance allows it to act as a kind of capacitor. The inductance creates a short-term energy storage device, allowing it to "smooth" out variations in the current. In this way, it can reduce the level of noise or ripple in the circuit.

Conclusion

The DFE252012F-6R8M=P2 fixed inductor is a popular component for dampening noise or ripple in many electronic circuits. Its shielded construction and high temperature rating make it suitable for a range of applications, from high-current DC-DC converters to satellite TV receivers. Its working principle is based on the concept of magnetic fields and electrical current, whereby two wire coils can create an inductance that can be used to regulate the flow of power in a circuit.
