Fixed inductors are electronic components that act as a light, passive electric device used to store energy in the form of a magnetic field. Fixed inductors are commonly found in power and audio applications. A common type of fixed inductor is the CDPH4D19FNP-3R3MC. This article will discuss the application fields and working principle of the CDPH4D19FNP-3R3MC.The CDPH4D19FNP-3R3MC is a high power rating, high current rating, radial, ferrite core, axial inductor. It is commonly used in power circuits and can be employed in switching regulator circuits, usb charger circuits, battery charger circuits, power line filter circuits, high frequency inverters, and many other circuits that require high current and power ratings.The CDPH4D19FNP-3R3MC offers a wide, stable operating temperature range compared to other types of fixed inductors. It can handle high temperatures up to 125°C, and its operating temperature range is -25°C to +125°C. This makes the CDPH4D19FNP-3R3MC suitable for use in high temperature environments and for long term operation.The CDPH4D19FNP-3R3MC is also highly resistant to saturation, which means that it can handle large currents without excessive magnetic field generated or significant voltage drops. In addition, the inductance value of the device is stable up to high current ratings and is independent of the current level. The working principle of a fixed inductor is based on the fact that when a current is passed through a conducting wire, a magnetic field is generated around the wire. The strength of the magnetic field is proportional to the current that passes through it. The strength of the magnetic field is also influenced by the number of turns around the conducting wire. In the case of the CDPH4D19FNP-3R3MC, a ferrite core increases its inductance value by providing a high permeability path for the magnetic field which reduces the resistance and thus increases the current passing through the inductor. The inductor also has a higher number of turns and therefore a larger magnetic field is produced.The CDPH4D19FNP-3R3MC is suitable for use in a variety of applications ranging from SMPS, high power applications, communication equipment, automotive devices, and many other applications where a high current and power rating is required. The device is also ideal for applications that require a stable, yet low level, inductance value with a wide temperature operating range.In conclusion, the CDPH4D19FNP-3R3MC is a high power rating, high current rating, radial, ferrite core, axial inductor. It offers a wide, stable operating temperature range and is resistant to saturation. It is suitable for use in a variety of applications including switching regulator circuits, usb charger circuits, battery charger circuits, power line filter circuits, and high frequency inverters. Its working principle is based on the generation of a magnetic field in response to a current passing through the inductor, with the strength of the generated field proportional to the strength of the current.
