Fixed Inductors

Fixed inductors, commonly referred to as "chokes" or "coils", are components that store energy in magnetic fields when electric current passes through them. The MHQ1005PR39GT000 is a type of fixed inductor used in a wide range of applications where the resistance of the inductor is important to the proper operation of the system.

Application Field of MHQ1005PR39GT000

The MHQ1005PR39GT000 is primarily used in power filter circuits, where it reduces or eliminates high frequency interference caused by intermittently switched power supplies or switching power stages. They are also often used as reactive loads on the outputs of amplifiers, providing additional stability to the signal path.The MHQ1005PR39GT000 has found many other applications, such as in noise reduction circuits, to smooth the transfer of power from one section of a circuit to another, as coupling and decoupling of signals, for resonance suppression, and as a similar protection against dangerous capacitive loads.

Working Principle of MHQ1005PR39GT000

Fixed inductors use a core material, usually ferromagnetic, to provide the magnetic field necessary to store electrical energy. The core is then wrapped in a conductive wire, usually copper or aluminum, which forms a winding around the core. When electric current passes through the winding it creates a magnetic field around the core, which stores the energy.The resistance of the inductor is determined by its size and material. The larger and thicker the winding, the higher the resistance of the inductor. The inductance also depends on the core material; ferromagnetic materials have higher inductances than non-ferromagnetic materials.The MHQ1005PR39GT000 is designed with a ferrite core which provides a very high inductance. It is then wrapped with copper wire, making it highly resistant to resistive loads. The combination of these two components provides excellent filter performance and stability.

Conclusion

The MHQ1005PR39GT000 is a type of fixed inductor used for a wide range of applications. Its ferrite core and copper winding provide excellent filter performance and stability, making it ideal for power filter circuits, noise reduction circuits, and other similar applications. It is commonly used to protect circuits from high frequency interference, provide additional stability to amplifiers, and to suppress resonance.
