Fixed inductors are essential components for any electronic system, as they are used to regulate current and store energy. The fixed inductor CDRH125NP-4R4NC is a reliable and high-performance component for those engineers and designers who need an easy-to-use, high-quality inductor. In this article, we will explore the application field and working principle of the CDRH125NP-4R4NC fixed inductor.

The CDRH125NP-4R4NC fixed inductor was designed for high-density Printed Circuit Board (PCB) applications that require an extremely low profile and a low power consumption. This inductor can be used to filter high frequency noise, and in power transmission and distribution systems. It is also suitable for automotive and telecom applications.

The CDRH125NP-4R4NC is a surface mountable device with a 4.4 mm package size and 25 Amp current rating. It is fully RoHS-compliant, and it offers ATO and RoHS compliance options for customers who need such compliance. The maximum DC resistance is 0.49 Ohms, and the inductance range is from 30 uH to 470 uH. The rated power dissipation is 370 mW, and it has a maximum operating temperature of 125°C.

An inductor is a passive electrical component that stores energy in a magnetic field when a current passes through it. The CDRH125NP-4R4NC fixed inductors are of the three-terminal type, with two terminals for connecting the winding and the other terminal for connecting the magnetizing current. The inductance of this type of inductor increases with the increase of the voltage applied across it.

The core material of the CDRH125NP-4R4NC is made of ferrite, which is a magnetic oxide material with a high permeability and low hysteresis loss. The ferrite core has a high saturation magnetic field strength, so it is capable of storing a large amount of energy in the magnetic field.

When a current flows through the windings of the CDRH125NP-4R4NC inductor, a magnetic field is created in the core material. The magnetic flux is then transferred from the core material to the windings and the current induces in the coil. The current in the coil and the induced voltage generate the back EMF, which is the reverse voltage induced in the coil. This back EMF opposes the current flow, and a large amount of energy is stored in the magnetic field.

The CDRH125NP-4R4NC fixed inductor is also a low EMI component. Its high permeability core material and quality windings provide excellent attenuation of high-frequency noise. The low EMI performance makes this component suitable for applications such as filters for high-frequency noise.

In summary, the CDRH125NP-4R4NC fixed inductor offers reliable and low-cost performance for a wide range of applications. Its high permeability core material, low DC resistance, and low profile package make it suitable for high-density PCBs. Its low EMI rating makes it suitable for high-frequency noise filtering applications. Its three-terminal design ensures easy installation, and its ATO and RoHS compliance options make it an ideal component for automotive and telecom applications.
