Fixed inductors are components that store energy in the form of a magnetic field. They are used to filter noise, provide impedance matching, and help to provide protection against voltage surges in electrical circuits. The 2890R-36J is a common type of fixed inductor that is found in a variety of applications.

The 2890R-36J is made from a ferrite core material that has a high saturation point, which means it can withstand a higher voltage without reaching its maximum magnetic field. The shape of the core is a disc, which helps to provide good coupling between the conductor and the core material. The external size is 28 millimeters in diameter and 36 millimeters in height.

One of the most common applications for the 2890R-36J is in radio frequency (RF) power filters. They are often used in cellular radios and base stations to block incoming signals that are not part of the desired communication channel. They can also be used to help reduce interference from other RF sources like the sun. In these applications, they are usually placed in the antenna path to reduce the effect of outside interference.

The 2890R-36J is also used in switching power supplies and other DC/DC converters. This is because they are able to quickly store and release energy when needed. This helps to regulate voltage and current in the circuit, making it more efficient. In these applications, they are often used in conjunction with other components like capacitors and diodes to help control the flow of power.

The working principle of the 2890R-36J is relatively simple. When an alternating current is placed through the inductor, it creates a magnetic field. This magnetic field can store energy which can then be released when needed. The energy stored in the magnetic field is proportional to the current flowing through the inductor. This means that when the current is increased, more energy is stored and released. This is why they are so useful in applications like power supplies and RF filters.

The 2890R-36J is a versatile fixed inductor that can be used in a variety of applications. It is suitable for use in RF power filters, switching power supplies, and other DC/DC converters. It is small and easy to install, and is able to quickly store and release energy when needed. This makes it an ideal solution for many different types of applications, and is sure to continue to be popular in the years to come.
