Fixed Inductors

A fixed inductor, also known as a fixed-value inductor, is one of the most common types of components used in electronic circuits. It is an electrical component that generates a magnetic field when an electric current passes through it. The SRN6028-220M inductor is a typical through-hole fixed type with a rated inductance value of 220mH.

Application Fields

The SRN6028-220M fixed inductor is widely used in electronic products, such as computers, cell phones, audio equipment, and navigation systems. It can be used as an AC filter for restoring signals from power line transmission and as a matching resistor for antennas and receivers. Additionally, it can be used in power factor correction (PFC) circuits and self-resonant resonator circuits. Moreover, it is used in a variety of electrical and electronic designs, such as power supplies, RF amplifiers, and oscillators.

Working Principle

The SRN6028-220M fixed inductor works by producing a magnetic field in response to an electric current. When a steady electrical current passes through the inductor coil, a magnetic field is generated which then produces a self-induced voltage (back EMF). This back EMF is an opposing force which resists the change of current. The stronger the current, the stronger the magnetic field. Thus, the SRN6028-220M fixed inductor can act as a filter, limiting or smoothing the amount of current flowing in the circuit and producing regulation of the voltage level.

In addition, because of its self-resonance frequency, the SRN6028-220M fixed inductor can be used in oscillator circuits to shape and maintain a voltage wave at a specific frequency. The resulting output voltage signal is pure and its amplitude and frequency remain consistent and predictable.

Conclusion

The SRN6028-220M fixed inductor has a rated inductance value of 220mH and is commonly used in electronic products such as computers, cell phones, audio equipment, and navigation systems. It works by producing a magnetic field in response to an electric current, which produces a self-induced voltage known as a back EMF. The SRN6028-220M inductor is used for signal restoration, power factor correction, and as a matching resistor in antennas and receivers. It also serves as an oscillator to shape and maintain a voltage wave of a set frequency.
