Fixed Inductors are components that act as filter passives for radio-frequency (RF) circuits. The part number CDRH127-7R6NC is a good example of a fixed inductor, and the following passage will discuss its application field and working principle.

Application Field

The CDRH127-7R6NC is an axial-lead inductor, designed to meet the surge current requirements of power supply filters in multi-output AC/DC power adapters. This type of inductor can also be widely used in multi-output DC/DC converters, notebook computer power supplies, LED power supplies, and other DC switching power supplies. With a maximum rated current of 4A, the CDRH127-7R6NC has a wide range of applications.

Working Principle

At its most basic level, a fixed inductor works by storing energy within a magnetic field. As a current is passed through the inductor, a magnetic field forms around it. The magnetic field then induces a voltage across the inductor which causes a counter-electromotive force to oppose the current. This process is known as inductance, and it can be used to reduce the amplitude or voltage of an alternating current waveform. This makes the CDRH127-7R6NC ideal for use in power supplies, where it is used to filter out unwanted frequencies and harmonics.

The CDRH127-7R6NC is also designed to withstand high levels of surge current, without any increse in its operating temperature. This is achieved through its tight winding pattern, which ensures that no large overlapping loops are present, minimizing the total inductance. As a result, the inductor can handle higher levels of current without overheating, prolonging its operational life.

Conclusion

In conclusion, the CDRH127-7R6NC is a fixed inductor designed for use in multi-output AC/DC power adapters, and other DC switching power supplies. Its tight winding pattern ensures that it is able to withstand high levels of surge current, while also filtering out unwanted frequencies and harmonics. Its wide range of applications, as well as its durable design, makes it an ideal choice for many power supply designs.
