Fixed inductors are electrical components that are made up of coiled conductors within a core material. They are commonly used to store energy in electric circuits and to establish inductance in filter networks. The 3090-121H fixed inductor is a high-power component with a current rating of 4.0A, a maximum voltage rating of 250V, and a tolerance of ±20%.

The 3090-121H fixed inductor has a size of 12.5×12.5×5.2mm and is designed to be used in circuits with high currents that require low DC bias. This makes the component suitable for use in a range of applications, such as motor control, circuit protection, and audio frequency filters. In addition, it is also suitable for use in power converters, as it has a low dissipative power loss.

The working principle of the 3090-121H fixed inductor is based on the principle of inductance. When current flows through the coiled wires, an electromagnetic field is created, which induces a voltage in the wire. This voltage produces an opposite current, which in turn causes a reaction in the wire, creating a magnetic field. This magnetic field interacts with the field of the current-carrying wire to produce a voltage in the wire. This voltage is inversely proportional to the rate of change of current.

The 3090-121H fixed inductor can be used in circuits that require high-power, low-temperature operation. It is ideal for use in automotive, industrial, and military applications that require reliable performance and long life. It also features a low self-resonant frequency, which ensures that the inductor does not need to be designed with a very large wire length, which reduces the cost and complexity of the design.

As the 3090-121H fixed inductor is designed for use with high currents, it features internal shielding to limit the inductance\'s capacitance, which can be a problem in circuits with high frequencies. It also has a lower DC resistance than other low power inductors, making it suitable for high voltage applications. Additionally, it features excellent temperature stability, making it reliable for continuous use in circuits.

The 3090-121H fixed inductor is an excellent choice for applications that require reliable power and low temperature operation. Its high current rating and low DC bias make it suitable for use in a number of applications. Its internal shielding and low DC resistance make it suitable for high voltage applications, while its excellent temperature stability ensures it is reliable for extended use in circuits.
