Fixed inductors, also known as chokes, have many uses in electronics and provide the same basic purpose--to limit the flow of certain electric currents. The LQH32MN471J23L fixed inductor is an example of a part capable of performing this action, and is found in a variety of applications from power supply filtering to signal processing. This article will provide an overview of the device, discuss its working principle, and explore its various applications.

The LQH32MN471J23L is a fixed inductor characterized by a low profile, high Q performance in a small, surface mount package. The inductance of the part is 4.7uH, and its DC resistance ranges from 0.98-1.02ohms. It has an operating temperature range of -40℃ to 85℃, with a maximum current of 1.17A (at 25℃). Other specifications include inductance tolerance of ±20% (at 100kHz, 0.25Vrms), maximum SRF (Self Resonant Frequency) of 500 MHz, and saturation current of 1.6A.

The primary purpose of the LQH32MN471J23L is to limit the flow of certain electric currents. This can be accomplished by way of magnetic fields, which can cause inductive reactance (opposition to current flow) to be generated. A fixed inductor, such as the LQH32MN471J23L, contains a coiled wire of insulated copper. When electric current passes through the coil, a magnetic field is generated. This magnetic field in turn induces an electromotive force (EMF) in the coil, which opposes the current flow. The amount of EMF generated can be determined by the following equation:

EMF = 2 * pi * frequency * number of turns * magnetic field strength

An increase in the frequency of the current flow will result in an increase of the EMF. The LQH32MN471J23L serves to filter out high frequency noise in power supplies and other circuits, as it has a maximum SRF of 500MHz. This enables the device to reduce interference and improve the performance and reliability of the circuit by limiting background noise.

Another application of the LQH32MN471J23L is in signal processing, specifically in tasks related to signal filtering. This device is also capable of acting as an impedance matching device, allowing for poor transmission line matches to be improved. Other uses include antenna matching, antenna tuning, impedance bridging, and DC blocking, among many others.

In conclusion, the LQH32MN471J23L is an example of a fixed inductor designed to limit the flow of certain electric currents. The device is used mainly in power supply filtering and signal processing applications, though it can also be used in many different tasks. Its low profile, high quality performance, and small surface mount package make it a highly desirable component in many devices.
