Fixed inductors are electrical components that store energy in the form of a magnetic field. They are also known as inductors, coils, chokes, or reactors. They come in a variety of shapes and sizes and can be custom made or commercially available off-the-shelf.

The S0402-15NJ3 is a small surface-mount inductor that is generally used in high-frequency circuits, ranging from 1 KHz to 1 GHz. It is ideal for applications such as power amplifiers, oscillators, filters, switching power supplies, motor or voltage control circuits, and output stages.

Working Principle of S0402-15NJ3

The S0402-15NJ3 works on the principle of electromagnetic induction. When an alternating current passes through the inductor\'s windings, a magnetic field is generated proportional to the current flow. This magnetic field induces a voltage in the winding, which opposes the original current flow and and reduces the amount of current that passes through the inductor in a process called self-inductance. This effect allows the inductor to act as a high-frequency filter, blocking an AC current while allowing a DC current to pass.

The S0402-15NJ3 has an inductance value of 15 nH and a tolerance of ±20%. This values vary depending on the size of the inductor and the shape of the core. The inductor has a DC resistance of approximately 0.072 OHMs and a maximum current rating of 0.59A@40°C.
