Fixed inductors are passive components that are used in electrical and electronic circuits to store energy in an electromagnetic field, produce a constant voltage or current, and to provide electrical signal filtering. The distinct feature of fixed inductors is the ability to provide a constant, predetermined amount of energy, allowing them to function as signal or power dampers, voltage regulators, circuit filters, and other functions.The LQW31HN39NJ03L is an example of a fixed inductor. It features an inductance (L) of 3.0nH, a self resonant frequency (fres) of 35.3MHz, a rated current (I) of 1.0A, a voltage coefficient of inductance (Vc) of 8.0mV, and a surface mount construction with an operating temperature ranging between -55°C and +125°C. The LQW31HN39NJ03L is typically used in power supplies, pulse transformers, DC-DC converters, antennas, and other applications where a low profile and high frequency inductor is required. The device is also used in automotive, communication, and consumer applications, including smart cards, modems, and other electronic equipment.The operating principle behind a fixed inductor is fairly straightforward. Electromagnetic coupling occurs between two loops of wire to form an inductor with a specific inductance value. When a current passes through the first loop of wire, it creates a magnetic field that induces a voltage in the second loop of wire. The resulting voltage opposes the current, thus producing a self-inductance. When the current in the loop of wire changes, the magnetic field will also change, which induces more voltage in the second loop of wire. As a result, the voltage level in the inductor will change, while its inductance remains constant. This type of behavior is referred to as its inductance-to-voltage behavior. In some cases, the inductor may be connected to a voltage source, and its behavior will be governed by the resistor-inductor-capacitor (RLC) circuit\'s self-induced voltage-to-current relationships.The LQW31HN39NJ03L fixed inductor is especially suited for high frequency applications, mainly due to its low inductance, low voltage coefficient, and high frequency self resonant frequency. It is important to note that due to its relatively low inductance, the LQW31HN39NJ03L will not be able to provide as much energy as a higher inductance inductor would. However, its high frequency performance allows it to be used in applications such as DC-DC converters and antennas, where higher frequencies are required.In summary, the LQW31HN39NJ03L fixed inductor is a widely used component in electricity and electronic circuits. It features an inductance of 3.0nH, a self resonant frequency of 35.3MHz, a rated current of 1.0A, and a voltage coefficient of inductance of 8.0mV. It is typically used in high frequency applications, including power supplies, pulse transformers, DC-DC converters, antennas, and other applications where a low profile and high frequency inductor is required. Its operating principle is based on electromagnetic coupling between two loops of wire, and its inductance-to-voltage behavior is governed by its self-induced voltage-to-current relationship.
