Fixed inductors, named for their ability to maintain a stable inductance value, are passive two-terminal electrical components that use a coil of wire to store energy in a magnetic field. The IR04RU122J is a common fixed inductor used in many applications and electronic circuits. This article will discuss the application field and working principle of the IR04RU122J fixed inductor.

What is the IR04RU122J?

The IR04RU122J is an axial leaded, self-shielding power inductor. It is a cylindrical, tubular component with a length of 11.7 millimeters (mm) and an outer diameter of 7.1 mm. The rated inductance for the IR04RU122J is 0.122 µH with a current rating of 2.2 A. The rated DC resistance (DCR) is 0.8 Ohm, while the saturation current (ISAT) is 4.5 A.

Application Field of IR04RU122J

The IR04RU122J fixed inductor is commonly used in DC/DC switching power supplies, AC/DC converters, snubber circuits, motor drives, and many other electronic circuits. It is especially useful for applications that require high energy storage in a small form factor, as well as for switching power supplies that need to handle large currents. Additionally, the IR04RU122J’s low DCR and high continuous current capabilities make it useful for power management in high-power systems.

Working Principle of IR04RU122J

An understanding of the working principle of the IR04RU122J fixed inductor begins with a knowledge of basic inductor behavior. An inductor stores energy in an external magnetic field when current passes through its coil. This magnetic field can then be used to induce a voltage in the coil, which in turn induces a current. When the current passes through the coil it creates a new magnetic field, which is additive to the original one. This process, known as inductance, is the result of inductor behavior and is the working principle of the IR04RU122J.

The IR04RU122J has an axial leaded construction that allows for easy wiring in a PCB. The inductor is composed of a coil of wire, an interior iron core, and a magnetic material. The iron core provides a magnetic path for the energy stored in the coil, while the magnetic material provides a magnetic field that adds to the field already present in the coil. This combination of components allows the IR04RU122J to store energy in a constant magnetic field, which is very useful for applications that involve switching power supplies.

Conclusion

The IR04RU122J fixed inductor is a common electronic component found in many applications. It is used to store energy in a magnetic field, which is useful in switching power circuits and other applications that require high current and energy storage. The IR04RU122J is a cylindrical, axial leaded component with low DCR and high saturation current capabilities, making it an ideal choice for power management in high-power systems.
