Fixed inductors are electronic components widely used in the fields of electronic circuit engineering and communication engineering. The PM7032S-221M-RC is a fixed inductor which is designed specifically for these two classes of applications. This paper will introduce the application field and working principle of the PM7032S-221M-RC.

PM7032S-221M-RC Overview

The PM7032S-221M-RC is a fixed inductor commonly used in electronic circuit engineering and communication engineering. It is made from ferrite cores and windings of pure copper wire. Its dimensions are 0.59 x 0.47 x 0.33 in (15.24 x 11.97 x 8.36 mm). It has a rated inductance of 220 uH±20% and a direct current (DC) resistance of 0.49 ohms. It is suitable for use in applications that require inductance values between 200 and 250 uH. It also has a maximum saturation current of 51 amps.

Application Fields

The PM7032S-221M-RC is widely used in electronic circuit engineering and communication engineering. In electronic circuit engineering, this fixed inductor is mainly used in power supplies, DC-DC converters, switching regulators, and filter circuits. In communication engineering, the fixed inductor is used in hybrids, voltage-controlled oscillators, filters, antennas and other radio frequency circuits.

Working Principle

The working principle of the PM7032S-221M-RC can be explained using Faraday\'s law of electromagnetic induction. When a conductor is placed in a changing magnetic field, an electromagnetic force is induced in the conductor. The magnitude of the force is proportional to the strength of the magnetic field and the rate of change of the magnetic field. This induced current creates a magnetic field which opposes the original magnetic field. This phenomenon is known as inductance.

In the PM7032S-221M-RC, the magnetic field is generated by the ferrite core and it creates the inductance. The current is driven through the conductor, inducing a voltage drop across the inductor. The voltage drop increases as the current increases and the resulting inductance helps to filter out higher frequencies, allowing DC current to pass through the conductor while blocking AC current. This is how the PM7032S-221M-RC can be used to create resonant circuits.

Conclusion

The PM7032S-221M-RC is a fixed inductor designed for use in electronic circuit engineering and communication engineering. Its application fields include power supplies, DC-DC converters, switching regulators, filter circuits, hybrids, voltage-controlled oscillators, filters, antennas and other radio frequency circuits. The working principle of the PM7032S-221M-RC can be explained using Faraday\'s law of electromagnetic induction. The magnetic field generated by the ferrite core creates the inductance, while the current driven through the conductor induces a voltage drop across the inductor which helps to filter out higher frequencies, allowing DC current to pass while blocking AC current.
