Fixed inductors, also referred to as chokes, are generally non-polarized electrical components mainly found in radio frequency circuits. This type of inductor is made of a coil of insulated wire wrapped around a ferrite or iron core, and is used to reduce or eliminate high frequency noise in a circuit. LQM21NN3R3K10L is a type of high-frequency, shielded, SMD fixed inductor, with a rated current of up to 3.5A and an operating temperature range from -40 degree celsius to +105 degree celsius.

This component is primarily used in signal processing for communication systems, AC/DC switching power supplies, and various other high-frequency applications. They are designed to provide a large amount of inductance to a low-current signal, without passing a large amount of DC bias current. This type of inductor is also used to filter electromagnetic interference, reduce ripple noise, and provide a stable voltage supply to the circuity.

The working principle of LQM21NN3R3K10L is based on the concept of Faraday’s Law of Induction. In an electrical circuit, when the current through a conductor such as a coil changes, it will induce a voltage across the turns of the coil. This voltage is proportional to the rate of change of the current through the coil and the number of turns the coil has. In the case of LQM21NN3R3K10L, the windings of the coil are made from an insulated wire, which is wound around a ferrite or iron core. The magnetic field produced by the current in the coil interacts with the ferrite core to induce a voltage across the coil. This voltage then reacts with the current, resulting in the production of inductance.

The inductance is a measure of the amount of opposition a circuit presents to changes in current. This is a tremendously important property, as it is used by the circuit to filter out high-frequency signals and attenuate any unwanted noise. The inductance will also determine the rate at which the current changes, i.e., its reactance, which is the main factor in the performance of a radio frequency circuit.

The inductance produced by the LQM21NN3R3K10L is typically measured in microhenries (µH). The inductance values for this type of inductor can range from 2.2 to 10 µH, depending on the construction and the number of turns per layer of the inductor. This makes them ideal for applications requiring high-frequency signal and noise filtering.

In addition to providing an efficient and effective filtering function, the LQM21NN3R3K10L inductor also has high power-handling capabilities. Its rated current is up to 3.5A, and it can withstand temperatures ranging from -40 degree celsius to +105 degree celsius. This makes it suitable for all types of high-frequency applications, including AC/DC switching power supplies and communication systems.

In summary, LQM21NN3R3K10L is a high-frequency, shielded, SMD fixed inductor. It is mainly used in signal processing for communication systems, AC/DC switching power supplies, and various other high-frequency applications. It works on the principle of Faraday’s Law of Induction, and its inductance values range from 2.2 to 10 µH. This makes it ideal for applications requiring high-frequency signal and noise filtering, and also provides high power-handling capabilities.
