Fixed inductors are widely used in electronic equipment to store energy in a magnetic field and to create electrical signals or filters to block unwanted signals. The PM75-220K-RC inductors are a type of fixed inductors used in various devices, such as audio systems, communications, motion control, and audio/video equipment. This article will cover the application fields and working principle of the PM75-220K-RC inductors.

Applications Fields

The PM75-220K-RC inductors are typically used in audio systems, communications, motion control, and audio/video equipment. In audio systems, inductors are used to create desired signals, such as treble and bass, and to block undesired signals from entering the system. In communications, they are used to create elements of the data transfer, such as frequency, time, and other parameters. In motion control, they are used to provide the signals needed to control movements. In audio/video equipment, they are used to buffer components against electrical noise.

Working Principle

The PM75-220K-RC inductors are a type of fixed inductors, which use a coil of wire to store energy in a magnetic field when a voltage is applied. The inductor stores energy in the form of a magnetic field until the voltage is removed. When the magnetic field reaches a certain threshold, the coil releases the energy as a current flow. The amount of energy released is determined by the inductance value of the inductor. The number of turns of wire on the coil is also a factor in determining the inductance value of the inductor.

The PM75-220K-RC inductors are typically used in applications that require low power, such as audio systems, communications, motion control, and audio/video equipment. Low power inductors are designed to operate at a low voltage and current, as compared to high power inductors. The PM75-220K-RC inductors have an inductance value of 220 mH and have a rated current of 75mA. The inductors have a low DC resistance of 0.8 ohm, which helps minimize losses.

The PM75-220K-RC inductors also have a high self-resonant frequency, which is important for applications that require high frequency signals, such as communications and audio/video equipment. The self-resonant frequency is the frequency at which the inductor will start to resonate, and is determined by the inductance value of the inductor. The PM75-220K-RC inductors have a self-resonant frequency of 220 kHz.

Conclusion

The PM75-220K-RC inductors are a type of fixed inductors used in various applications, such as audio systems, communications, motion control, and audio/video equipment. The inductors have an inductance value of 220 mH and a rated current of 75mA. The inductors also have a low DC resistance and a high self-resonant frequency, which makes them suitable for use in applications that require high frequency signals. The PM75-220K-RC inductors are a perfect choice for applications that require low power, high frequency signals, and low DC resistance.
