Working Principle

Fixed inductors are typically made up of a wire coil that is wound around a core material such as ferrite, ferromagnetic, or coreless forms. As electrical current passes through the wire, a magnetic field is generated around the coil. The magnetic field is concentrated by the core material, which increases the inductance of the coil. This allows the MHQ0402PSA1N4ST000 to produce a very high inductance. As current passes through the coil, a voltage drop occurs due to the generation of the magnetic field. This voltage drop can be controlled by the size of the coil and the number of turns in the winding. A greater number of turns and a larger core will produce higher inductance and greater voltage drop.

The advantage of fixed inductors is that they are more reliable than variable inductors. Variable inductors usually have a core material (usually ferrite or ferromagnetic) that moves, which causes the inductance of the device to change with the core position. Fixed inductors, on the other hand, have a fixed core material which results in a more stable and reliable inductance value and voltage drop. This makes fixed inductors ideal for applications that require a constant voltage drop.

The MHQ0402PSA1N4ST000 is a high performance fixed inductor with a wide range of applications. Its low cost and high power rating make it an attractive choice for a wide variety of projects.
