Working Principle

The working principle of the LTF4022T-2R2N-D is the same as that of any other inductor. When an AC current is passed through the inductor, it creates a magnetic field, which stores energy. This energy is then released as an AC current when the applied voltage to the inductor is reduced.

The core material of the LTF4022T-2R2N-D is made of ferrite, which increases its ability to store energy. This allows the part to perform at higher frequencies while providing greater saturation current and higher power handling. The shielding provided by the all-metal housing additionally reduces emissions and improves performance.

Conclusion

The LTF4022T-2R2N-D is a high-performance shielded power inductor designed for use in various mobile and industrial applications. With an inductance range between 0.22uH and 10.0uH, the part is suitable for use in Switching Regulator Output Filtering, DC/DC Converter, DC/AC Converter, and Transformer Winding applications.

LTF4022T-2R2N-D inductor works on the terms of inductance which creates a magnetic field and stores the energy, this stored energy is then released when voltage is reduced. It is made with a ferrite core material, which increases its power handling and efficiency. The shield lets reduce the emissions and improve performance.
