Fixed Inductors: CDRH4D18CLDNP-3R3PC Application Field and Working PrincipleInductors are common components found in digital circuitry, motor control systems, and other electro-mechanical systems. They are used to store energy in a magnetic field and regulate electric current. One type of inductors is known as a fixed inductor, which can be found in the CDRH4D18CLDNP-3R3PC fixed inductor family. This article examines the application field and working devices of this particular family and considers how it works in practice.Fixed inductors are used for a variety of purposes, ranging from DC-DC power conversion to motor control systems. As the name implies, they are used to fix a particular amount of energy in a magnetic field. As electric current passes through the inductor, a flux linkage is produced, which stores energy as a magnetic field. This can later be released as electrical energy. Fixed inductors can handle high temperatures, high frequency signals, and higher voltages than other types of inductors.The CDRH4D18CLDNP-3R3PC fixed inductor family is designed for use in DC/DC power converters, as well as high-density integrated circuits. It contains an integrated shield for increased performance and improved noise immunity. The CDRH4D18CLDNP-3R3PC family features a rated current of 1.8A and specialized self-saturation levels for a variety of applications. The inductance range is between 4nH and 10.5nH.When working, the CDRH4D18CLDNP-3R3PC inductor receives an alternating current that causes its magnetic field to fluctuate between a positive and negative charge. This flux is alternately repelled and attracted by the magnetic field of the inductor, creating a back EMF that opposes the original current. The degree to which this opposes the original current is determined by the inductance of the inductor and its value.When the current changes direction, the inductor resists the change, creating an inductive reaction. This inductive reaction stores energy in a magnetic field, which can later be released as electrical energy. This stored energy can be regulated by adjusting the inductance of the inductor.The CDRH4D18CLDNP-3R3PC family of fixed inductors is designed for high-density circuit applications that require low-resistance, high-efficiency power conversion. It offers high temperature stability, low-resistance features, and a high EMI shielding level. This makes it suitable for a variety of high-density integrated circuit applications.In summary, the CDRH4D18CLDNP-3R3PC family of fixed inductors is designed for use in a range of high-density integrated circuits, including DC-DC power converters, motor control systems, and other electro-mechanical systems. Its resistance and efficiency level are ideal for high-density circuits, while its high temperature stability and EMI shielding level provide excellent noise immunity. These features all come together to make the CDRH4D18CLDNP-3R3PC family of fixed inductors a suitable choice for a range of integrated circuit applications.
