Fixed inductors are an important electronic component in the power supply system. In addition to its own power supply function, it also plays an important role in the filter circuit of power supply. SLF7055T-4R7N3R1-3PF is a type of fixed inductors.

Application field

SLF7055T-4R7N3R1-3PF is mainly used for power supply, such as switching power supply, linear power supply and so on. When these power suppliers are used, the noise of power supply should not be too loud. That\'s why the inductor is needed. Different inductance can filter the noise and attenuate the signal and interference. And SLF7055T-4R7N3R1-3PF has this function.

The SLF7055T-4R7N3R1-3PF can also be used for the telecommunication telecom base station power supply. It can filter the noise from the power supply, and improve the overall stability of the system.

Furthermore, the SLF7055T-4R7N3R1-3PF can used in the power system, reducing the quality influence of electromagnetic noise. It also can be used for the electromagnetic compatibility, and the oscillation of pulse circuit and other application field.

Working principle

The working principle of SLF7055T-4R7N3R1-3PF is mainly based on the role of the magnetic field. It is very similar to the role of the transformer in the power supply, which is to change the frequency of the current. When the electric current that passes through the inductance causes a certain magnetic field, the magnetic field causes a reverse force against the current.

The inductance can block the high-frequency pulse current, so the electric current that passed through the inductance will reduce. This is the principle of low-pass filter, which is also the working principle of the inductor. The frequency that can be blocked is determined by the inductance. High inductance can block low frequency and low inductance can block high frequency.

The SLF7055T-4R7N3R1-3PF can block wide band width frequency, thus reducing the noise generated by the power supply. It can also reduce the interference between signals, so as to ensure the stability of the system.

Conclusion

In summary, the SLF7055T-4R7N3R1-3PF is an important fixed inductor with a wide range of application fields. It is mainly used to filter the interference of power supply and reduce the electromagnetic compatibility. The working principle is to use the magnetic field to block high frequency current, thus ensuring the stability of the power supply system.
