Fixed Inductors are electrical components capable of providing a predictable amount of inductance, regardless of current or voltage fluctuations. The CDRH124NP-3R9MC is one of the most versatile of its kind. It can be used in a variety of applications thanks to its flexible design and variety of form factors.

The CDRH124NP-3R9MC is designed to work within frequency ranges between 600kHz and 3GHz. As this range of frequencies is wide enough for most applications, the CDRH124NP-3R9MC is often used in RF devices. These devices may have applications in mobile devices, transmitters, replaceable antennae and other areas of consumer electronics.

The most common form factor for the CDRH124NP-3R9MC is as a flat wire inductor, in which the inductor itself is wound onto a rectangular core. This form factor is relatively compact and can be adapted to fit into most spaces, making it suitable for use in tight or complex circuits. Another popular form factor is that of a loop wire inductor, in which each of the coils is wound in a loop and held within a circular core.

The core material of the CDRH124NP-3R9MC varies depending on its use, but generally is made of ferrous or non-ferrous metals. The core will in turn dictate the inductance value of the device, as well as its electrical resistivity. The properties of the ferrous or non-ferrous metals can also affect the frequency response and saturation levels of the inductor.

The working principle used within fixed inductors such as the CDRH124NP-3R9MC is based on Faraday’s law of induction, which states that an electromotive force (EMF) is generated in a conductor whenever a magnetic flux through it varies. This EMF is proportional to the rate of change in the flux, and is inversely proportional to the conductor’s geometrical shape and size.

In practice, this means that when a current is passed through a coil of wire, a magnetic field will be created around it due to the electrons sweeping around the wire due to the current. If an alternating current is passed through the wire, the magnetic field generated will constantly vary, which in turn will create an EMF in the coil.

The magnitude of this EMF is determined by the shape of the coil, the size of the core, the number of turns within the coil and the frequency of the current passing through it. This EMF is then used within the CDRH124NP-3R9MC to induce an electrical current, which provides an electrical resistance and thus helps to regulate the current flow within the circuit.

For an application requiring a high amount of inductance, a multi-coil version is available. This involves multiple coils of wire wound around a core, the total number of coils being equal to the number of turns within each individual coil. This creates a much higher amount of inductance, which can be further enhanced by careful selection of the core material.

Overall, the CDRH124NP-3R9MC is an incredibly useful and versatile fixed inductor. Its flexibility, form factors and range of applications make it ideal for a wide range of consumer electronics. Additionally, its reliance on Faraday’s law of induction allows it to provide an effective means of regulating the current within a circuit.
