Fixed Inductors

Inductors are one of the most common electronic components and are widely used in electronic circuit design. Among the many types of inductors, the fixed inductor is the most basic and widely used type. PM1008-4R7K is one of the fixed inductors. This article will explain its application fields and working principles.

Application Field of PM1008-4R7K

PM1008-4R7K is a fixed inductor with excellent performance. It is mainly used in common electronic circuit design in the fields of radios, audio equipment, and signal processing equipment. It is often used as a filter circuit, voltage regulator, frequency divider, amplifier, and other applications.

The main parameters of this inductor are as follows: maximum DC current is 490mA, rated DC current is 130mA, inductance is 4.7uH, tolerance is 20%, and rated voltage is 250V. The size of the inductor is 10x8x5.08mm, and the weight is approximatly 0.38g.

Working Principle of PM1008-4R7K

The working principle of the PM1008-4R7K inductor is similar to that of other inductors, that is, it can store energy in the magnetic field. It is composed of a winding and a core. The winding is composed of enameled silicon steel inner and outer plates and a vertical wire core. When the alternating current is input, a sufficiently strong magneto-induced electric potential is generated. This electric potential can enable induction of current.

When PM1008-4R7K inductor is used in a circuit, it is mainly used to shape and filter a signal. It adds inductance reactance to the circuit, so that the current can take the form of choppers, filters, and decoupling circuits. The PM1008-4R7K inductor uses a ferrite material as an inductance core to increase the size and performance of the inductor.

Conclusion

PM1008-4R7K is a high-performance and widely used fixed inductor. This inductor is mainly used in radio, audio equipment, and signal processing equipment. It has high inductance and can be used as a filter circuit, voltage regulator, frequency divider, amplifier, etc. The working principle of the PM1008-4R7K is similar to other inductors, which is to store energy in the magnetic field.
