The 4922-271L inductor can also be used as a current transformer in order to monitor high-current applications and for over-current protection.

Working Principle of 4922-271L

The 4922-271L inductor works on the principle of Faraday’s law of induction. When a current is passed through the inductor, a magnetic field is generated which induces a voltage in the inductor. This harmonic voltage attracts and saturates the core of the inductor, creating a back EMF that limits the increase in current.The magnetic core of the 4922-271L is constructed in such a way that it allows for reduced core losses. The metal core also helps to reduce the amount of electromagnetic interference (EMI), which is particularly beneficial in noise-sensitive areas.

Conclusion

The 4922-271L fixed inductor is an ideal solution for applications in which high currents need to be monitored and EMI needs to be reduced. It is suitable for use in switching power supplies, DC-DC converters, LED lighting applications, and audio amplifiers. The inductor works on the principle of Faraday’s law of induction and is designed with a metal core that reduces core losses and attenuates EMI.
