Fixed inductors are electronic components used to store energy in the form of electric and magnetic fields. In particular, they form the basis for various inductors used in electronic circuits, such as loudspeakers, radio transmitters, computers, and medical devices. This article will discuss the application field and working principle of the 2890R-26G.

The 2890R-26G is a fixed inductor designed to offer high inductance and low ESR (equivalent series resistance). It has an inductance of 2.9mH, an operating temperature range of -40 to +85C, and a maximum rated voltage of 15Vdc. This inductor is typically used in power conversion, filters, motor control systems, and energy efficiency systems. Additionally, it can be used as a low ESR decoupling capacitors, or as a current source in audioclass-D amplifiers.

The 2890R-26G operates on the principle of electromagnetism. At its core, it is composed of two components: a ‘core’ and a ‘winding’. The core is typically made of iron or another ferromagnetic material, while the winding is made from copper wire. When a current passes through the inductor, it produces an electromagnetic field which induces a voltage in the winding of the inductor. This voltage opposes the current passing through the inductor, leading to an increase in the inductance of the inductor.

The 2890R-26G also has a wide range of applications in the industrial and consumer sectors. It is often used in switched mode power supplies (SMPS) and DC-DC converters, as it has a superior efficiency compared to other inductors. Additionally, the 2890R-26G is used in motor control systems, such as pumps and motors that require a large amount of current. In this application, the inductor operates as a filter to reduce the noise generated by the motor and ensure more reliable operation.

Finally, the 2890R-26G is also used in the design of radio frequency (RF) circuits. In this role, it functions as an impedance matching component to ensure efficient signal transmission. With its low ESR and high inductance parameters, the 2890R-26G is able to reduce the losses associated with RF signal transmission, and provide a high level of performance.

In conclusion, the 2890R-26G is a fixed inductor suitable for a wide range of applications, including power conversion, audio amplification, RF transmission, and motor control. It operates on the principle of electromagnetism, and its low ESR parameters make it particularly suited for use as a decoupling capacitor and an impedance matching component.
