Fixed inductors are basic electronic components made from a coil or loop of wire. They opportunistically store energy in the form of a magnetic field when a current passes through them, and are widely used in electrical and electronic circuits to affect current flow in various ways. CDRH104R-2R5NC is a common fixed inductor which was initially designed to be used in industrial applications, but has been finding more uses in consumer electronics recently.

Application Field

The CDRH104R-2R5NC series is mainly intended for use in industrial environments, especially for those requiring high performance and stability. Examples of applications in which CDRH104R-2R5NC devices are widely used include: frequency filters, power regulators, industrial motor drives, automatic temperature control circuits, static switches, computer systems, and automotive electronics. This particular series is also suitable for manufacturing equipment and communications systems.

Working Principle

A fixed inductor works on the same basic principle as any inductor. It stores electrical energy and provides resistance to the flow of current through it. In general, when a current passes through a coil of wire, a magnetic field is generated in the surrounding area. The strength of the magnetic field is determined by the magnitude of the current passing through the coil, as well as the number of turns and geometry of the coil. When a voltage is applied across the inductor, electrical current then starts to flow, producing a strong magnetic field inside the core of the inductor. This is known as Oersted\'s law.

The magnetic field inside the core of the inductor causes a decrease in the amount of current that can be supplied to the inductor. This is known as back EMF or counter electromotive force. This can limit the maximum current that is supplied to the inductor, since it will reduce as the current increases. This is useful for controlling the rate at which current is supplied to the inductor.

Furthermore, when the current through an inductor is changed, the magnetic field it creates will also change, creating a voltage which opposes the change in current. This is known as the inductive reactance, and it is inversely proportional to the frequency of the current. This is important to note when working with inductors, as it can reduce the efficiency of an inductor if not accounted for.

In the case of the CDRH104R-2R5NC fixed inductor, it has a rated inductance of 2.5 nH, and can handle up to 1 A of continuous current, with a maximum voltage of 40 VDC. It is typically made up of a coil of wire, wound around a ferrite or other magnetic core, with encapsulation to protect it from the environment.

Conclusion

The CDRH104R-2R5NC fixed inductor is a common electronic component widely used in many different industrial and consumer applications. It works on the principles of a basic inductor, where it stores a magnetic field based on the current passing through it, and provides back EMF to limit the amount of current that is supplied. It has a rated inductance of 2.5 nH, with a maximum voltage rating of 40 VDC, and can handle up to 1 A of continuous current.
