Inductors are electrical components that serve as a storage devices for energy and are typically used in industries such as automotive, power supplies, audio amplifiers, telecommunications, and scientific instruments. The 2890R-42F is a fixed inductor and is especially popular in the telecoms industry.
Inductors are designed to either store or filter energy from alternating current (AC) sources such as power lines. Fixed inductors, such as the 2890R-42F, have a fixed inductance value and thus provide the same amount of inductance regardless of the frequency of the AC input. The 2890R-42F is designed as a low-loss solution for both single-ended and differential-mode noise filtering applications. It provides an inductance range of 0.6 to 1.4 microHenries and an inductor-to-ground capacitance of over 5pF, making it an ideal solution for designs where high throughput is needed.
The 2890R-42F is suitable for use in a wide range of applications, such as power supplies, switch-mode power supplies, and motor control systems. In addition, the product can be used as a high frequency filter in variable frequency drives, as well as a noise filter or an impedance matching component in telecommunications and audio systems.
The working principle of the 2890R-42F fixed inductor is based on Faraday\'s law of induction. This law states that a changing magnetic field creates an electromotive force in a conductor. This electromotive force produces a current in the conductor, and this current is proportional to the rate of change of the magnetic field. As the current changes, it produces an additional magnetic field, which opposes the applied electromotive force. This process, known as electromagnetic induction, increases the opposition of the conductor to the applied electromotive force.
The internal structure of the 2890R-42F allows the inductor to effectively convert the AC current into a steady DC current. When the external current is applied to the inductor, the internal magnetic field increases, thus increasing the inductance. This process is known as self-induction. The increase in inductance means that there is greater opposition to the external current and thus, less of this current passes through. The inductor stores energy in the form of a magnetic field and this energy is effectively passed onto the load when the external current is removed. This allows the inductor to act as a filter, allowing the steady DC current to pass through while blocking the AC current.
In summary, the 2890R-42F is a fixed inductor, popular in the telecoms industry, that provides an inductance range of 0.6 to 1.4 microHenries. With an inductor-to-ground capacitance of over 5pF, it is ideal for designs where high throughput is needed. Its working principle is based on Faraday\'s law of induction and it is capable of effectively converting the AC current into a steady DC current. It is suitable for use in a wide range of applications, such as power supplies, switch-mode power supplies, motor control systems, and telecommunications and audio systems.
