Fixed inductors have been part of electronic and electrical applications for many years. The 2890-08G is a helical wire-wound fixed inductor that is manufactured by Coilcraft. It is designed for applications where a high current density is needed, and is a good choice for many applications where a large diameter inductor may not fit. This inductor is offered in two size packages – a 3.2mm x 3.7mm package and a 5mm x 7mm package. It is rated for power levels from 0.8 watts up to 2.0 watts.

The 2890-08G is designed to have low DC resistance at low frequencies, enabling it to provide more inductance at lower current levels. Its wire-wound design is able to handle very large currents without saturation, which makes it suitable for many high current applications. The helical wire-wound construction also ensures that the inductance stays relatively constant across a wide range of frequencies. The inductor is able to withstand a large tolerance of ±20%, allowing it to be used in sensitive applications.

The 2890-08G’s application field includes switching power supplies, DC/DC converters, battery management systems, and DC/AC converters. It can be used in all types of power electronics circuits, including buck, boost, and inverting circuits. It is also suitable for charging circuits, as its low DC resistance allows for efficient power transmission. Moreover, it is suitable for high frequency decoupling and high-current filtering in consumer and industrial applications. It can also be used in voltage regulator circuits, amplifiers, and other RF circuits.

The working principle of the 2890-08G is based on the magnetic field generated when a current passes through a wire. Since this inductor is wire-wound, the magnetic field generated is much greater than with a regular inductor of the same size. This allows the inductor to store more energy and convert it into more inductance. The helical wire-wound design makes the inductance relatively constant across a wider frequency range, meaning that the inductor can be used in multiple applications. Furthermore, due to its high current capacity, the inductor can handle extreme current levels without saturation, enabling it to be used in power electronic circuits.

In conclusion, the 2890-08G is an excellent choice for many different applications. Its wire-wound construction and low DC resistance enable it to be used in sensitive circuits, and its large current capability makes it suitable for high current applications. The inductor’s ability to remain constant across a wide frequency range allows it to be used in multiple applications, making it a great choice for many different applications. As a result, the 2890-08G is a great choice for any application where a high current density is needed.
