Fixed Inductors

The CDRH4D18CNP-101NC-H Fixed Inductor is used in many diverse applications. It can be used in DC-DC converter applications requiring high current and fast switching, and in digital switching circuits.

The CDRH4D18CNP-101NC-H is a Ferrite-Core Fixed Inductor that is rated at a maximum of 10A/100MHz. This inductor can handle maximum power levels reaching up to 36 watts. A wide range of inductance values can be achieved with the CDRH4D18CNP-101NC-H, depending upon the size of the core selected and the number of turns used. The inductance of the inductor can range from 0.7 µH to 470 µH. The inductor also has excellent ESR and DCR values.

The CDRH4D18CNP-101NC-H is a type of inductor called a fixed inductor. Fixed inductors are constructed using a core made of ferrite, iron powder, or air. These cores increase the inductor\'s inductance by concentrating the magnetic flux generated by the current passing through the conductors. The core material also helps to minimize the losses due to eddy current generation. The ferrite core of the CDRH4D18CNP-101NC-H also helps to reduce the inductor\'s sensitivity to electromagnetic interference (EMI) generated by nearby sources.

Working Principle

The basic working principle of the CDRH4D18CNP-101NC-H is based on Faraday\'s Law of Induction. This states that an electromotive force (emf) is generated in a conductor that is exposed to a varying magnetic field. The magnitude of the generated emf is proportional to the rate of change of the magnetic field. In an inductor, the current in the coil generates a magnetic field. The rate of change of this magnetic field induces a voltage in the coil, producing a back emf opposing this current, thus indicating that the inductor opposes changes in current.

In the inductor, depending on its design, the current in the windings creates a magnetic field which stores energy when the current is increasing, and the inductor requires energy when the current decreases. This is known as reactive power. It is important to note that the inductance of the inductor plays a major role in determining the amount and rate of reactive power. The higher the inductance, the greater the amount of reactive power.

The CDRH4D18CNP-101NC-H is designed with a high inductance rating of up to 470 µH. This can provide high-current switching, while also ensuring low inductor losses. This helps to ensure a low output voltage drop, even at high currents. The ferrite core of the CDRH4D18CNP-101NC-H helps to minimize losses due to eddy current generation, as well as improving EMI immunity. It is ideal for use in DC-DC converters, digital switching circuits and other applications where high peak currents and fast switching are required.
