Fixed Inductors

Inductors are components that store and release electrical energy. They are commonly used in a variety of electronic devices due to their ability to transfer current. The CDRH4D28NP-220NC fixed inductor is a component that is used in applications such as home audio systems, power supplies, and medical equipment. It has a variety of features that make it an ideal choice for a wide range of applications.

CDRH4D28NP-220NC Application Field

The CDRH4D28NP-220NC fixed inductor is a surface mount device with an inductance of 0.22µH. It is composed of a ceramic core, a ferrite core, and a terminal. This inductor is designed for use in DC to DC converters, power supplies, home audio systems, medical equipment, and other electronic applications. It is designed to provide a stable inductance value while supplying high current levels. It can handle DC and limited AC currents up to 2.2A. The inductance of 0.22µH decreases the EMI radiation, and its small size allows for easy board space saving.

CDRH4D28NP-220NC Working Principle

The working principle of the CDRH4D28NP-220NC fixed inductor is based on Faraday\'s Law of induction. When a current passes through the coil of wire, a magnetic field is produced. This magnetic field will induce a voltage in the coil in the opposite direction of the current, which is called back EMF. The back EMF will oppose the current and this creates a resistance, which is known as the inductance. The more turns of wire in the inductor, the higher the inductance will be and the stronger the back EMF will be.The CDRH4D28NP-220NC fixed inductor is designed for use in applications that require high frequency operation. The terminal is designed to support a wide range of frequencies and can handle up to 2.2A of current at frequencies up to 300 kHz. This makes it suitable for use in high frequency switching applications, such as DC converters and power supplies.

Conclusion

The CDRH4D28NP-220NC fixed inductor is an ideal choice for a variety of DC to DC converter, power supply, home audio, and medical equipment applications. Its high current ratings, small size, and inductance value of 0.22µH make it a great choice for applications where space is at a premium. Furthermore, its terminal is designed to handle frequencies up to 300 kHz, making it well-suited for high frequency switching applications. For these reasons, the CDRH4D28NP-220NC fixed inductor is a great choice for a wide variety of applications.
