Fixed inductors are electrical components that carry an inductance value and are fabricated in a package with two or more terminals. They are typically used in radio frequency (RF) applications, such as in mobile phones, digital receivers, television tuners, handheld radios, and in high frequency (HF) or very high frequency (VHF) circuits. The 3090-820J is a type of fixed inductor, which is widely used in radio frequency applications to provide an inductance. The inductor is made from an air core material, which is used to electrically isolate the inductor from components that are connected to it.

Introduction to the 3090-820J

The 3090-820J is a type of fixed inductor that is optimized for use in RF circuits. It is formed by a multi-layer coiled wire and is enclosed within a black-colored plastic case. The inductor is capable of providing up to 1.07 A of current, and has an inductance of 0.24mH. The inductance of the inductor is determined by the number of turns on the multi-layer coil, which in turn affect the electrical performance of the inductor. The 3090-820J is suitable for use in high frequency circuit applications and is also bonded for automatic insertion in RF circuit boards.

Application Field of the 3090-820J Inductor

The 3090-820J inductor is widely used in HF and VHF circuits, such as in mobile phones, television tuners, handheld radios, and digital television receivers. The inductor is designed to be used in symmetric circuits, such as RF amplifiers, frequency converters, and oscillators. The inductor can also be used in SW3 (single antenna whip) and FM radio broadcasting applications. In addition, the inductor is also used in antenna systems, antenna boosters, and antenna feeding lines.

Working Principle of the 3090-820J Inductor

The working principle of the 3090-820J inductor is based on Faraday\'s law of electromagnetic induction. According to the law, a voltage induced in a conductor when a magnetizing field changes, is proportional to the rate of change of the magnetic flux. This means that when the magnetic flux in a coil or inductor is changed, a voltage is induced in it. The process of induction occurs due to time varying fields, such as alternating current (AC) or pulsing DC signals.

In the case of the 3090-820J inductor, when a current passes through the turns in the multi-layer coil, a magnetic field is generated. This magnetic field is then used to induce a voltage in the inductor, which is proportional to the rate of change of the magnetic flux. The magnitude of the voltage induced in the 3090-820J inductor is determined by the size of the inductance and the rate of change of current passing through the inductor.

Conclusion

The 3090-820J is a type of fixed inductor that is widely used in HF and VHF circuits. It is made from a multi-layer coil and is enclosed within a black-colored plastic case. The inductor is suitable for symmetrical circuits, such as RF amplifiers, oscillators, and frequency converters. The working principle of the 3090-820J inductor is based on Faraday\'s law of electromagnetic induction, which states that an induced voltage is proportional to the rate of change of the magnetic flux.
