LQW2BHN18NK13L

Fixed inductors are electrical components that store electric charge in a way that is practically beneficial to its circuit. Inductors, sometimes known as coils, coils, chokes, or reactors, are made up of circuits containing two or more windings that are immersed in an iron core. The LQW2BHN18NK13L is a bobbin wound inductor from TDK that features an open construction and a high self-resonant frequency of 18GHz.

The core of the LQW2BHN18NK13L is made from a combination of ferrite and a powdered iron core. This combination provides it with exceptional magnetic properties and amazingly low losses when used in high frequency circuits. The windings are comprised of tin-plated copper, providing excellent RF shielding and a minimal amount of capacitance. As it stands the inductor is enclosed in a plastic case, but this may be removed if necessary.

The main application of the LQW2BHN18NK13L is in radio-frequency circuits operating above 50MHz, where it is used to form a filter, typically a low-pass filter. This filter works by passing certain frequencies, while blocking out certain frequencies, and is an essential part of any radio-frequency circuit. This particular inductor is suitable for making high-frequency filters because it has a low self-resonant frequency and low losses at frequencies above 18GHz.

The working principle of this inductor can be explained by examining the electrical characteristics of the windings and iron core. The windings consist of several loops of wire each placed parallel to each other. Ferrite core creates an intense magnetic response allowing the windings to encode magnetic energy. When voltage is applied to one winding, the current induces a magnetic field in the core which then induces a current in the other winding. This current in the second winding then produces a second magnetic field. This mutual induction provides the inductor with its magnetic response and filtering properties.

The LQW2BHN18NK13L is a high-performance inductor and is well-suited for radio-frequency applications. Its combination of ferrite and powdered iron core provides exceptional magnetic properties, and tin-plated copper windings provide excellent RF shielding. With its high self-resonant frequency of 18GHz and low losses at higher frequencies, this inductor is great for making filters.

In short, the LQW2BHN18NK13L fixed inductor is an essential component for any radio-frequency circuit operating above 50MHz. Its combination of ferrite and a powdered iron core provides it with excellent magnetic properties, and its tin-plated copper windings give it low losses at higher frequencies. Working on the principle of mutual induction, this inductor is perfect for making high-frequency filters and is widely used in radio-frequency circuits.
