Fixed inductors can generally be divided into two categories, namely air core inductors and ferromagnetic core inductors. 2890R-22G belongs to the former categories. 2890R-22G is a series of radial leaded air core chip inductors made by Sulex. It is appropriate for use in a wide variety of applications including telecommunication, various industrial systems (ATS/HVAC/UPS systems), and other electronic applications.

The physical parameters of 2890R-22G can be summarized as follows. Its size is 2890, meaning that its outer diameter is 2.8mm, its inner diameter is 0.9mm, and its height is 0.9mm. It also has two versions, namely 2890R-22G 2.2mH version and 2890R-22G 2.4mH version. It can be applied in frequencies from 0-200MHz, with a maximum DC current of 50mA. Lastly, 2890R-22G has an inductance tolerance of 10%.

The recognition code of 2890R-22G is 2340005. Typical applications can be summarized as follows: automotive electronics, consumer electronics, wireless phones and satellite communication. Additionally, 2890R-22G is used for various types of circuits, and it can be found in circuits requiring impedance matching, antenna coils, power driving circuits, band-limited channels, and oscillation circuits.

The working principle of 2890R-22G is based on the principle of electromagnetic induction. This basic principle states that when an electric current flows through a conductor, it creates a magnetic field around it, and the field induces a voltage in any other conductor that is placed in the magnetic field. As a result, when an alternating or a peak-to-peak current is supplied to the inductor, it creates a changing magnetic field. These changing fields cause the induction coils to induce voltage, which in turn drives the current around the inductor. The induced current creates magnetic fields of the opposite direction. As these opposing magnetic fields cancel each other out, the inductor acts as a low-pass circuit. As a result, the inductor helps to increase the efficiency of a system by minimizing the amount of energy consumed.

In summary, 2890R-22G is a fixed inductor used in a wide variety of applications including telecommunication, automotive electronics, consumer electronics, and satellite communication. It is based on the principle of electromagnetic induction and works by creating a changing magnetic field that induces a voltage in the inductor, providing a low-pass circuit that is more efficient than other types of circuits.
