Working Principle of LQH3NPZ101MMEL

The working principle of the LQH3NPZ101MMEL fixed inductor is based on the effect of mutual inductance. When this effect is established, a store of energy is created in the form of a magnetic field, which is responsible for the development of inductance. From the effect of mutual inductance, the current carrying wire wrapped in the coil creates a varying magnetic field. This varying magnetic field will be capable of producing a low electric current in the other wire as a result of the mutual inductance. This low electric current then creates its own magnetic field and thus, an inductance is developed.
