Fixed inductors are components that store electric energy in magnetic fields. The S0402-27NH2D is a fixed inductor of the most common type, composed of a coil of wire wound around a core, and is particularly used in a wide range of electronic products.

The specifications of the S0402-27NH2D fixed inductor include an inductance of 27nH (nanohenries) at a maximum current of 200mA, and a saturation current of 260mA. The size of the inductor is a mere 0402, meaning it is 0.04 of an inch by 0.02, and its operating temperature range is -55°C to +125°C. This makes it suitable for applications where size is of great importance such as the design of wearable electronics or miniature consumer products.

The main factor to examine in a fixed inductor is its self-resonance frequency, which is the frequency at which the coil and core form a tuned circuit. The S0402-27NH2D has a self-resonance frequency of 3.5GHz, which is relatively high compared to other components of its size. This makes it suitable for high frequency applications, such as diode circuits, voltage regulators, and oscillators.

The working principle of the S0402-27NH2D fixed inductor is straightforward. A coil of wire, typically copper, is wound around a ferromagnetic core. When a current passes through the coil, it creates a magnetic field around it which stores the energy from the current. The inductor will then resist any change in the current, while the energy is released back into the circuit when the current is removed. Furthermore, the inductance of the coil is determined by the number of turns, the core material, and the diameter of the coil.

The S0402-27NH2D is mainly used as part of radio frequency circuits. It is especially useful for high frequency applications, such as satellite communication, and cellular phone systems. Additionally, the inductor can also be used in power supplies, and voltage regulators.

The S0402-27NH2D fixed inductor is a common and versatile component which is suitable for a wide variety of applications. Its small size and high self-resonance frequency make it particularly suitable for high frequency circuits and other applications where size is of great importance.
