Fixed inductors are a type of passive electronic component located in a wide variety of applications and can encompass a range of physical styles. Inductors can be thought of much like transformers and have two primary functions: to store energy in the form of magnetic energy, and to provide resistance or reactance to signals passing through it. Many inductor designs exist and one popular example is the LQW18AN 10NJ 10D. It is one of the most common styles of inductor but serves the same basic functions regardless of design.

What is an LQW18AN 10NJ 10D Inductor?

The LQW18AN 10NJ 10D inductor is a surface-mounting chip-style inductor in a variety of package variants. These inductors are based on the wire-wound technology and provide very low resistance up to 10nJ. They come with three pins which connect the self-supporting component to a circuit board. The pins act as an electrical contact for the inductor in order to send and receive signals.

Application Field

Inductors, like the LQW18AN 10NJ 10D, serve a variety of application fields, and not every inductor has the same application. Due to its size and relatively small power rating, it is mainly used in low-power applications such as dc-dc converters, mobile phones, and laptops. It can also be used for high-density mounting applications such as in portable consumer electronics, such as digital still cameras, PDAs, and printer circuit boards. The inductor can also be used in mobile communication gear, game consoles, and digital TV equipment.

Working Principle

The main function of the LQW18AN 10NJ 10D inductor is to serve as an electrical filter, providing desired resistance or reactance so that signals passing through it are not corrupted. This property is known as inductance, and is determined by the number of turns in the inductor’s coil, as well as the type of substrate material used to construct the circuit board. Electrical current through the inductor creates an opposing magnetic field, which is then able to filter signals that pass through it.

Inductors like the LQW18AN 10NJ 10D are designed for fixed performance and are not dynamical components. While most are designed to be either “hard” or “soft” magnets, their inductance does not increase or decrease with changing signals. Therefore, it is important to match the inductance requirement of the circuit in order to avoid any signal corruption.

Conclusion

The LQW18AN 10NJ 10D inductor is a popular style of inductor that serves a variety of applications, from low-power dc-dc converters to mobile phones, portable consumer electronics, and beyond. This inductor is based on the wire-wound technology and, despite its small size, is able to provide very low resistance up to 10nJ. Its primary function is to act as an electrical filter, providing desired resistance or reactance so that signals passing through it are not corrupted, and is able to do so with excellent repeatability.
