Introduction

Fixed inductors, also known as ferrite chip beads, air coils, and so on, are a kind of passive component for electronic circuits. They are widely used in DC/DC converters, cellular phones, personal digital assistants, laptop computers, automotive electronics, and other electronic apps. The LQH55DN220M03L is a fixed inductor specifically designed for high frequency and low power applications. This article will discuss the application field and working principle of the LQH55DN220M03L fixed inductor.

Application Field

The LQH55DN220M03L fixed inductor is a high-quality inductor that is specifically designed for high frequency and low power applications. It is capable of operating in frequencies up to 500 MHz and can handle power up to 100 mW. In addition, the LQH55DN220M03L is a small form factor inductor, measuring only 2.2 mm x 2.0 mm x 0.8 mm in size. This makes it ideal for use in space-constrained designs.The LQH55DN220M03L is ideal for use in automotive electronics, mobile phones, personal digital assistants (PDAs), laptop computers, cameras, industrial equipment, radar systems, and other high-frequency, low-power applications. It is also suitable for applications in which a low ESR (equivalent series resistance) is required, such as power filters and signal integrity circuits.

Working Principle

An inductor is a passive component that stores energy in the form of a magnetic field. The inductance of an inductor is related to the permeability of the core material, the number of loops in the coil, and the area of the core. When a current is applied to the inductor, a magnetic field is created and the current will produce a voltage across the inductor. This is known as induction.Inductors are used in electronic circuits to filter out unwanted frequencies, to decouple DC and AC signals, and to serve as chokes in power supply circuits. The LQH55DN220M03L fixed inductor is specifically designed for high frequency and low power applications. It has a low DC resistance and a high inductance, making it ideal for use in signal filtering circuits.

Conclusion

The LQH55DN220M03L fixed inductor is a high-quality inductor specifically designed for high frequency and low power applications. It is capable of operating in frequencies up to 500 MHz and can handle power up to 100 mW. It is also a small form factor inductor, measuring only 2.2 mm x 2.0 mm x 0.8 mm in size, making it ideal for use in space-constrained designs. The LQH55DN220M03L is ideal for use in automotive electronics, mobile phones, PDAs, laptop computers, cameras, industrial equipment, radar systems, and other high-frequency, low-power applications. Its working principle is based on the principle of induction, in which a current passing through the inductor will produce a voltage across it.
