Fixed inductors are components that store energy in an electromagnetic field in an electrical circuit. A fixed inductor is a device that is designed to provide a certain amount of inductance in a circuit. Inductance is a measure of how well a device stores the electrical energy in a form of magnetic field within the device. Typically, fixed inductors are used for various applications, such as energy storage, power filtering, and voltage control.

The 2890R-16J is an example of a fixed inductor that is used in both commercial and military applications. It is a high-reliability inductor with the ability to handle up to 20 volts. The operating temperature range is from -40 to +85 degrees Celsius. It is designed for automated surface mount assembly and is hermetically sealed for improved life expectancy.

The 2890R-16J is an axial inductor and its core material is permalloy. The inductance is specified at 2.3 microhenrys (µH), and its resistance is 0.2 ohms. Its electrical construction consists of two enameled copper windings which are wound around a high-permeability core. The lead wire is tinned copper, and the inductor is able to be mounted using through-hole or surface mount technology.

In terms of working principle, the 2890R-16J is an inductor that stores energy in an electromagnetic field. When a voltage is applied across the inductor, a current starts to flow through it. This is a result of the coil’s inductance, which is the measure of how well the coil opposes changes in current flow. As the current flows through the coil, a magnetic field is generated, which causes the coil to store energy. This stored energy can then be used to provide inductive reactance in the application.

The 2890R-16J is mainly used in commercial and military applications, where it performs a variety of tasks. In the automotive industry, it is typically used for voltage control, such as those found in ignition systems. In the aerospace industry, it has been used in missile guidance systems and low-frequency radio receivers. In the defense industry, it has been used in electronic countermeasure systems. It has also been used in medical electrical equipment, such as pacemakers.

In conclusion, the 2890R-16J is a fixed inductor that is designed to provide a certain amount of inductance in a circuit. It is mainly used in commercial and military applications, where it performs a variety of tasks. Its working principle is based on the principle of storing energy in an electromagnetic field. This stored energy can then be used to provide inductive reactance in the application.
