Fixed inductors are electrical components that consist of insulated windings, usually of copper, around a core of soft iron or ferrite. Certain inductors designed to operate at radio frequencies are wound on ceramic bodies. The inductor behaves as a conductor when a steady current is applied to it, and as a resistor when varying currents flow through it. 2890-22H is a type of fixed inductor.

The 2890-22H inductor is a surface-mount device (SMD), specifically designed for signal conditioning on high-density, digital-signal processing (DSP) board. This can be used to create a low-pass filter, band-pass filter, high-pass filter or notch filter. It can be used in power supplies, DC to DC converters, transformers, noise suppression circuits, power line transceivers, and similar applications.

The 2890-22H inductor has an inductance value up to 1uH, with a maximum surge current of 4A. The size of the inductor is small, 2.8mm x 2.0mm. As compared to other types of inductors, it offers better electrical performance at higher operating frequencies and improved thermal efficiency. The device has a built-in capacitor for signal filtering and EMI reduction.

The working principle of the 2890-22H inductor is simple. When a current is passed through its conductive winding, a magnetic field is created. The magnetic field generated in turn, opposes the flow of current in the winding, thus creating a voltage drop. This voltage drop across the inductor is called inductive reactance. The reactance of an inductor increases with the frequency of the current. Thus, the 2890-22H components are used for voltage, current or power filtering.

The 2890-22H inductor is highly reliable and versatile. It is tolerant to vibration and shock and has a low-power consumption. The component is RoHS compliant and is compatible with various digital signal processing boards. It also has a high temperature range of -40 to +105°C and can work at high frequencies up to 10MHz.

The 2890-22H inductor is widely used in a variety of applications, such as consumer electronics, automotive and telecom. It is an ideal solution for applications requiring low profile devices with high-efficiency and high-reliability. It can also be used for filter networks, DC-DC converters, and voltage regulator modules.

In conclusion, the 2890-22H inductor is a small and reliable surface-mount device offering excellent performance at higher frequencies. Its core operating principle is the generation of magnetic fields through current flow in the winding, creating inductive reactance. This type of inductor is widely used in applications such as consumer electronics, automotive and telecom, as it offers superior reliability and efficiency.
