Fixed inductors are electronic components that convert electric energy into magnetic energy. These components allow for the efficient use of direct current in DC circuits and the efficient storage of energy in the form of magnetic fields. The S0402–4N7J3 is a type of fixed inductor that provides efficient, cost-effective magnetic energy storage for a wide range of applications.

The S0402–4N7J3 is a type of air core inductor with a compact size and a low cost per unit. This type of fixed inductor is suitable for applications such as reinforcing existing currents in DC circuits and providing high current carrying capacity in low power applications. Furthermore, due to its low profile, it can be used in space-constrained installations.

The operation of the S0402–4N7J3 is based on the induction law, which states that the magnitude of an induced voltage in an inductor is proportional to the rate of change of current passing through it. In the case of a DC circuit, this means that the inductor is able to generate magnetic energy in a controlled, efficient manner. In essence, it takes electrical energy from the circuit, stores it in the form of a magnetic field, and then returns it to the circuit when the current changes direction.

The S0402–4N7J3 is constructed from an insulated coil of copper wire that is shaped around a ferrite core. The number of turns and diameter of the wire, as well as the size and type of core, determine the inductance and other characteristics of the inductor. Different design parameters can also be used to tailor the inductor to suit different types of applications. For instance, in some high frequency or switching applications, a lower inductance and higher Q factor may be required.

The S0402–4N7J3 also has a high saturation current rating, which means that it can handle very high levels of current without going into thermal or core saturation. This makes the device well-suited for more dynamic applications where high levels of current may be needed for short duration periods. This device also offers a high self-resonant frequency and comes in both surface-mount and leaded versions.

In summary, the S0402–4N7J3 air core, fixed inductor provides efficient, cost-effective magnetic energy storage for a wide range of applications. This type of inductor can reinforce existing currents in DC circuits, provide high current carrying capacity in low-power applications, and offer a high self-resonant frequency in both surface-mount and leaded versions. Its high saturation current rating makes it well-suited for dynamic applications where high levels of current may be needed for short duration periods.
