Fixed inductors are components used in electrical and electronic circuits to store and release energy in the form of a magnetic field. The CDR125NP-120MC is a type of fixed inductor that is commonly used in a variety of applications. This article will discuss the application field and working principle of the CDR125NP-120MC.

Application Field:

The CDR125NP-120MC is a general purpose fixed inductor, with an excellent inductance-temperature coefficient. This makes the CDR125NP-120MC perfect for use in a number of different applications, ranging from power supplies and transformers, to filters, switching systems, oscillators, and more. In addition, it can be used in a variety of high frequency devices, including cellular phones, pagers, and GPS receivers.

Working Principle:

The CDR125NP-120MC is constructed of a coil of copper wire that is wound around a ferrite core. This core helps to reduce electro magnetic interference (EMI). The copper wire is insulated with a high quality film that provides excellent thermal and electrical insulation. The terminal of the inductor is plated with gold to improve oxidation resistance.

When current is applied to the copper wire, it generates a magnetic field which induces a voltage in the wire. This voltage is known as the back emf, which is proportional to the rate of change of current. This back emf then opposes the applied current, creating an inductance or opposition to current in the circuit. The magnitude of this inductance is determined by the number of turns in the coil, the core size and material, and the wire insulation.

When the current is removed from the coil, the magnetic field around the coil collapses. This induces a voltage in the same direction as the applied current, creating a reverse current induction known as “subsequent current”. This current is used to power another branch of the electrical circuit.

In this way, the CDR125NP-120MC works as an energy storage device, storing and releasing energy in the form of a magnetic field. It is capable of handling high frequency currents and is able to maintain a constant level of inductance over a wide temperature range.
