Fixed Inductors

A fixed inductor (LQH2MPZR33NGRL) is a type of passive electronic component typically characterized by a circular magnetic field. It is often used as part of a switch mode power supply or used to filter electrical noise.

Application Field

Fixed inductors are widely used in a variety of applications and industries, such as power electronics, automotive, consumer electronics, communications systems, aerospace, and robotics. Fixed inductors are used in switch mode power converters, AC/DC power supplies, and for DC-DC converters. Fixed inductors are also used to create resonance circuits for clock generation.

Working Principle

A fixed inductor works on the principle of Faraday’s Law of Induction. When a changing current passes through a wire coil, it creates a varying magnetic field inside the coil which then induces an EMF (ElectroMotive Force). This EMF is used to create a voltage across the inductor which can then be used to produce electrical current.

The fixed inductor can also act as a filter as it tends to attenuate high frequencies while allowing low frequencies to pass more easily. This application is used to reduce current and voltage ripple in DC-DC converters. In such applications, the inductor helps to reduce ripple current while providing a low impedance path to the load.

Conclusion

In short, fixed inductors are a versatile component widely used in a variety of electronic systems, from switch mode power supplies to resonance circuits. The LQH2MPZR33NGRL is a fixed inductor that is well-suited for a range of applications due to its ability to efficiently filter out electrical noise and attenuate high frequencies while allowing low frequencies to pass.
