Fixed inductors are a type of inductor that stores energy in its magnetic fields and holds a fixed amount of inductance or reactance. Fixed inductors are common electrical components used in a variety of applications. One class of fixed inductors is the SRP7030-2R2M, which is particularly useful in applications that require low noise level, high stability, and accuracy. This article will discuss the application field and working principle of SRP7030-2R2M and how it is useful in designing electrical circuits.

Applications

The SRP7030-2R2M fixed inductor is a monolithic chip inductor used in various electronic circuits. Some of its main applications are in:

• High frequency switching power supplies for laptop and desktop computers, as well as other consumer electronics products;
• DC/DC converters;
• Mobile phone power supplies;
• LCD televisions and monitors;
• And various other commercial and automotive applications.

Working Principle

The SRP7030-2R2M fixed inductor consists of a ferrite core, a conductor winding with a foil strip, and a shielding case. The core of the inductor stores the magnetic flux, while the conductor winding with a foil strip passes an electric current when a voltage is applied to it. The shielding case is used to reduce the effect of noise on the inductor. When a voltage is applied to the conductive winding, a magnetic field is generated and this creates an inductance. Inductance is the ability of a conductor to store energy in its magnetic field. The fixed inductance of the SRP7030-2R2M is 2.2 mH.

Pros and Cons

One of the main advantages of using the SRP7030-2R2M fixed inductor is its high noise reduction capability. It has a low-noise level which helps to reduce interference in circuits. The low-profile design and high-temperature capabilities of this inductor make it suitable for use in high-current applications. The SRP7030-2R2M has high-stability and accuracy levels even when exposed to high temperatures and currents. Furthermore, its inductance does not change significantly, even when exposed to significant temperature and voltage fluctuations.

On the downside, the SRP7030-2R2M fixed inductor is not suitable for DC frequencies, as the inductance value may vary substantially. In addition, this component is not suitable for high frequencies, as the high-frequency characteristics of the SRP7030-2R2M are not unusually superior. The shielding case is also not as effective as other types of shielding cases, so it might not provide sufficient noise reduction in applications requiring high levels of noise.

Conclusion

The SRP7030-2R2M fixed inductor is a monolithic chip inductor used for various applications in DC/DC converters, high frequency switching power supplies, and other electronic circuits. This inductor has a fixed inductance of 2.2 mH and offers low noise levels, high stability, and accuracy. Despite its high-level performance, the component has some drawbacks such as its incompatibility with DC frequencies and its lack of effective shielding.
