Fixed inductors are a type of electrical component which is used to provide fixed levels of inductance in a circuit. The typical inductor is made up of a coil of wire wound around some core material, which provides the necessary inductance within the circuit. The type of core material and the number of turns on the coil are key design parameters which will affect the inductance level of the inductor. The specific inductor of interest will be the S0402-10NH1D.

The S0402-10NH1D is a very small surface-mount, wire-wound, fixed inductor. It is rated for a maximum inductance of 10nH, and a current rating of 380mA, with a DCR rating of 0.014 ohms. The core of the S0402-10NH1D is made from ferrite material, which provides for a high level of saturation performance even at higher current levels. As with other inductors, the size and type of core material chosen has a direct effect on the inductance value of the device.

The S0402-10NH1D is suitable for a wide variety of applications, including power supplies, DC-DC converters, switching power supplies, charge pumps, Class-D amplifiers, audio equipment, and digital circuits. In power supplies, the inductor can be used to filter out high frequency noise from the output. In DC-DC converters they can be used to provide a stable output voltage, and in charge pumps, it can be used to store and regulate energy. The inductor can also be used in audio circuits, such as preamps and amplifiers, to provide frequency response shaping. The S0402-10NH1D can also be used to buffer digital circuits, providing a low impedance path for signals to pass through.

The working principle of a fixed inductor is based on Faraday’s law of induction, which states that a changing magnetic field will induce an electric current in a nearby conductor. When an alternating current is passed through the coil of an inductor, it causes the magnetic field to rise and fall, which in turn induces a current in the conductor. This current opposes the original current, thus providing the desired inductance. The core material of the inductor has a direct effect on the characteristics of the generated magnetic field, and the resulting inductance value.

In summary, the S0402-10NH1D is a small surface-mount fixed inductor, which is suitable for a variety of applications such as power supplies, DC-DC converters, and audio equipment. It is rated for a maximum inductance of 10nH, and is made from ferrite core material for improved saturation performance. The working principle of a fixed inductor is based on Faraday’s law of induction, and the core material chosen has a direct effect on the resulting inductance value.
