Fixed inductors play an important role in many electronics applications. The LQH31MN820K03L is an inductor that falls into this category. It is a versatile component that functions in multiple scenarios in order to improve both the performance and stability of the device it is connecting to. To better understand the application of the LQH31MN820K03L, it is important to understand its working principle.

Inductors store energy in electromagnetic fields generated by the electrical current in its coils. As current passes through the inductor, magnetic lines are created and stored around the winding of the inductor. The amount of stored magnetic field is directly proportional to the amount of current flowing through the inductor. The LQH31MN820K03L is a common-mode choke. It is essentially an inductor that is designed to reject any noise etc. that is common mode, meaning that is presented equally at both ends of the inductor. This type of inductor is commonly used in audio and video applications as it helps to ensure a high quality transfer of signals.

The LQH31MN820K03L is able to achieve this as it consists of two windings wound around the same magnetic core. The windings are placed in close proximity to each other and have a common ground. This means that the inductor will be able to filter out almost any interference that is common mode and will only pass the signals that are not common mode. It also has a small parasitic capacitor also known as the “stray capacitance”. This also helps to filter out any EMI/RFI noise which makes it an ideal choice for applications where signal integrity is important.

As well as filtering out EMI/RFI noise, the LQH31MN820K03L can also be used as an AC power line filter. It can help to suppress electric noise from an AC power line, as well as protect against ESD (electrostatic discharge). This is accomplished as the reactance of an inductor is frequency dependent, meaning that it will increase at high frequencies as opposed to decreasing like a capacitor’s reactance would do. Therefore, the inductor will work to block out any high frequency noise that is present on the power line.

The LQH31MN820K03L can also be used as an AC power supply filter. In this type of application, the inductor is used to attenuate all of the high frequency noise that is present in the power supply. This helps to reduce any jitter or “ringing” of the power supply. Additionally, the inductor also helps to eliminate the noise that is caused by the fan that the power supply uses for cooling.

Overall, the LQH31MN820K03L is an incredibly versatile component. It is able to serve multiple roles in any given application. Its ability to suppress EMI/RFI noise, filter out any ESD on a power line, and attenuate noise from a power supply makes it an ideal choice for many electronics applications. As such, it can be considered a key component of any device that requires a high level of signal integrity.
