Fixed inductors, which are also known as fixed coils, are generally composed of an inductive material, such as enameled wire, that is coated with a semiconductor material and wrapped in a coil form. The main purpose of a fixed inductor is to store energy in its magnetic field and induce a current when an alternating voltage is applied. The LQM21PN4R7MGHL is an example of a fixed inductor. This article will discuss the application field and working principle of the LQM21PN4R7MGHL.

The LQM21PN4R7MGHL is a relatively high-frequency, low-pass fixed inductor. It is designed to be a high-quality inductor with a low DCR and high current, and it is ideal for filtering applications. It can be used in power switching, audio, DC/DC converters, automotive, and cell phone application fields. Furthermore, because of its high Q factor, the LQM21PN4R7MGHL can also be used effectively in RF circuits, such as tuners and antennas.

The LQM21PN4R7MGHL consists of an iron-cored coil that has been enameled with polyurethane. This construction ensures a low DCR and a high SRF. Additionally, the inductor is encapsulated in a plastic shell that is resistant to temperature and humidity, making it suitable for use in a wide variety of applications. The LQM21PN4R7MGHL operates at frequencies up to 200MHz. It can handle up to 1.0A of current and has a rated voltage of 16V. Moreover, it has a self-resonant frequency of 1.7GHz, a inductance of 450uH, and a Q factor of up to 40.

The working principle of the LQM21PN4R7MGHL is similar to that of other fixed inductors. When an alternating voltage is applied to the terminals, it produces an electromagnetic field that induces a current flowing through the coil. The current is proportional to the applied voltage, and the inductance of the coil determines the amount of current produced. When the applied voltage changes, the amount of current changes as well. This changing current creates a magnetic field that is proportional to the applied voltage, which contributes to the filtering capabilities of the fixed inductor.

The LQM21PN4R7MGHL is a highly reliable inductor that is suitable for many different applications. It has a low DCR and SRF, making it suitable for use in RF circuits. Additionally, it is resistant to temperature and humidity, making it suitable for use in a wide variety of environments. Finally, the inductor has a high Q factor, making it ideal for filtering applications. With all these features, the LQM21PN4R7MGHL is sure to be a great choice for anyone in need of a fixed inductor.
