Fixed inductors are a type of passive electrical component that stores energy in the form of an electromagnetic field when energized. The 2890-42G is a fixed inductor designed for use in power supplies, DC/DC converters, and other electronic applications. It is rated for a maximum operating temperature of 105°C, a maximum inductance of 0.46mH, and a maximum DC current of 1.67A. In this article we will discuss the application field and working principle of the 2890-42G.

Application Field

The 2890-42G is designed for use in power supplies and DC/DC converters, as well as some other electronic applications. It is optimized for use in switching and linear regulators, providing an excellent solution for situations where high-frequency, low-loss energy transfer is needed. In particular, it is well-suited to applications requiring high frequencies in the order of hundreds of kilohertz.

The inductor is also suitable for use in LED drivers, motor drives, and other industrial automation applications. It provides excellent storage capabilities for energy, allowing for a more efficient transfer of energy from the source to the load. This makes it the ideal choice for power supplies and other applications requiring efficient power conversion.

Working Principle

The basic working principle of the 2890-42G is that of a coil of wire or other conductive material that induces or absorbs an electromagnetic field when energized. When an alternating current is applied to the coil, the electrical energy generated by the current causes an opposing magnetic field to form, which stores the alternating current in the form of energy. The result is an increased or decreased inductance of the coil, depending on the direction of the applied current and the number of turns in the coil.

The 2890-42G has an operating frequency range up to 100kHz and can handle a maximum peak current rating of 1.67A. When operated under specified conditions, it has a maximum inductance of 0.46mH. The inductor is also highly reliable, with an operating temperature range of -40°C to +105°C and a load life of up to 5,000 hours.

Conclusion

The 2890-42G is a fixed inductor designed for use in power supplies and DC/DC converters, as well as other electronic applications. It is optimized for high-frequency operations and features a high inductance and maximum peak current rating of 1.67A. The inductor is also highly reliable, with an operating temperature range of -40°C to +105°C and a load life of up to 5,000 hours.
