Introduction to Fixed Inductors

Inductors are electronic components that store and release electrical energy. They are made up of wire coils and can be used for various functions, such as filtering, tuning, and matching. A fixed inductor is an inductor that has fixed characteristics and whose value does not change throughout its operational lifetime. Fixed inductors are found in various power electronics applications, such as in switching converters.

CDRH4D16FBNP-220MCM Application Field and Working Principle

The CDRH4D16FBNP-220MCM is a fixed inductor with a shielded construction. It has an inductance of 17.7uH and a maximum current rating of 4.2A. It is a surface mount component, which makes it suitable for use in high-density applications such as mobile phones and other handheld devices. The CDRH4D16FBNP-220MCM is commonly used in switching power supplies, DC-DC converters, and other high-current applications.In its operation, the windings of the inductor act as a coil of wire, storing and releasing energy in the form of a magnetic field. When an alternating current runs through the coil, a magnetic field is created. The strength of this magnetic field depends on the amount of current passing through the coil. As the current changes, the strength of the magnetic field also changes, inducing a voltage across the coil. This phenomenon is known as inductance.The CDRH4D16FBNP-220MCM is designed to operate in high-frequency switching applications, such as DC-DC converters and switched-mode power supplies. It helps reduce the switching noise in these applications by providing a path for low-impedance current, which aids in the elimination of unwanted high-frequency noise. By diverting the high-frequency transient current away from the main circuit, the CDRH4D16FBNP-220MCM helps to protect sensitive components, such as semiconductors, from damage.

Conclusion

The CDRH4D16FBNP-220MCM is an example of a fixed inductor, a type of component designed for use in a wide range of applications. It is typically used in high-frequency switching applications such as DC-DC converters and switched-mode power supplies. Its shielded design helps reduce the amount of switching noise as well as protecting sensitive components from damage.
