Fixed Inductors

Fixed inductors are passive components used in a variety of electronic circuits, especially where an inductance component must be included with minimal fluctuation. Inductors will induce an electromotive force (EMF) as a function of the rate of the inductor\'s changing current. This EMF opposes any sudden changes, allowing signals to be held in place for a specified amount of time. As a type of electrical component, there are several types of fixed inductors that can be used in certain applications. One such example is the MHQ0402P1N4ST000.

MHQ0402P1N4ST000 Application Field

The MHQ0402P1N4ST000 is a type of fixed inductor designed for use in high frequency radio applications such as wireless internet, wi-fi, cell phones, and many others. It is commonly found in antenna designs, power supplies, RF amplifiers, DC/DC converters, and many other applications associated with digital signal processing. The MHQ0402P1N4ST000 is a surface-mount inductor, offering low-profile installation with minimal space requirements.

MHQ0402P1N4ST000 Working Principle

The basic principle behind any fixed inductor is that current will flow through a coil with an increase in energy, and that a voltage is induced in the coil as a result. The MHQ0402P1N4ST000 operates on the same principle- the coil is created from very fine copper enamel wire. The copper enamel wire is wrapped around a ferrite core, which increases the inductance of the circuit and also reduces high frequency noise levels. This helps to increase efficiency and reduce EMI (electromagnetic interference).

The MHQ0402P1N4ST000 has an inductance of 1.4nH, a DC resistance of 0.05 ohms, and a quality factor of 110. It also has a self-resonant frequency of 3.3GHz, making it ideal for high frequency applications. The high self-resonant frequency allows it to operate within a wide frequency range, considerably increasing its performance.

Conclusion

The MHQ0402P1N4ST000 is an example of a fixed inductor, designed for applications in high frequency radio signals. It offers minimal inductance fluctuations for steady operation, as well as a high self-resonant frequency for a wide range of operation. Furthermore, its small size and surface-mount design offer minimal space requirements, making it ideal for many modern applications.
