Fixed Inductors--CDRH3D14/LDNP-120NC

Fixed inductors, or chokes, are electronic components and have the ability to store electric energy and reduce electromagnetic interference. Their primary purpose is to control the flow of electrical current through a circuit. They are passive devices, without the need to be operated with an external source of power.

CDRH3D14/LDNP-120NC Overview

The CDRH3D14/LDNP-120NC is a fixed inductor which can be found in DC-DC converter modules, as well as other related electronic circuits. The inductor has a rated inductance of 1.2uH and an operating temperature range from -55℃ to +105℃. It has a DC resistance of 148mΩ and a rated current of 1.27A. The inductor is made up of a flat and rectangular shaped ferrite core, and features an epoxy resin coating and a metal terminal block. The ferrite core material is a combination of nickel, zinc, and iron, which reduces radial power loss by a large amount and makes for an efficient inductor.

Application Fields

CDRH3D14/LDNP-120NC inductors can be found in a variety of applications due to their superior performance characteristics. They are commonly used in DC-DC converter modules, switching power supplies, as well as other related electronics circuits. They are also used in computer Mother boards, power recliners, car starters, battery management systems, and other small devices that require power efficiency.

Working Principle

The working principle of a fixed inductor is based on the concept of magnetic flux. When a current is applied to a coil of wire, a magnetic field is produced, which in turn creates a flux inside the coil. This flux passes through the core material, and induces an electromotive force (EMF) in the coil. The magnitude of the EMF is proportional to the rate of change of the flux as it passes through the core material. The magnitude of the EMF is also proportional to the number of turns in the coil, as well as the operating frequency of the current. As the current alternates, so does the direction of the flux, and this produces an alternating EMF induced in the coil. This is known as inductive reactance and it opposes the direction of the current, thus reducing its magnitude. By using the right combination of core material, inductance, and number of turns, it is possible to create an inductor circuit that is tuned to the frequency of the current, and which operates efficiently.

Conclusion

In conclusion, the CDRH3D14/LDNP-120NC is a fixed inductor which can be found in a variety of electronic circuits. It has superior performance characteristics due to its special flat and rectangular shaped ferrite core material, which reduces radial power loss. The working principle of CDRH3D14/LDNP-120NC inductors is based on the concept of magnetic flux, which induces an electromotive force in the coil. This EMF opposes the direction of the current, thus reducing its magnitude. The CDRH3D14/LDNP-120NC is useful in many different application fields, such as DC-DC converter modules, switching power supplies, Mother boards, power recliners, etc.
