Fixed inductors, also called chokes, are electronic passive components that are designed to serve a specific purpose, such as filtering, coupling, and decoupling. They are generally constructed of a wire winding around a laminated ferrite or other magnetic core on which aluminum-alloy or other metal oxide materials have been applied. As its name implies, the inductance of a fixed inductor remains constant even when the current through the inductor changes.

CDR7D28MNNP-220NC is a type of fixed inductors, with parameters of 21.5uH and 8.2A. It consists of two parts: a winding part and a ferrite core. As a commercial service-free piece of equipment, this device is expected to operate in virtually any environment up to operating temperatures of up to 125 °C and humidity levels of up to 95%.

CDR7D28MNNP-220NC is mainly used for filtering and decoupling. Its winding part forms an inductor equipped to store energy when it is exposed to changing currents, which is used for suppressing and smoothing out AC-DC conversion effects. The stored energy is then potentially released into the circuit when the current is interrupted by the applied operating frequency, allowing the device to act as a damping solution.

The ferrite core of the CDR7D28MNNP-220NC assists the winding part in amplifying the induction process. In a nutshell, the core amplifies the level of oscillation in interactive processes when a varying amount of alternating current is applied. For instance, when the AC power increases more magnetic flux is created, and contrasting effects occur when the AC power decreases. This helps to amplify and stabilize the inductance of the inductor, which is typically used to deliver signals to the end equipment.

The working principle of CDR7D28MNNP-220NC is closely related to Faraday\'s law of induction. Faraday\'s law states that the magnitude of any induced EMF in a circuit is proportional to the rate of change of the magnetic flux passing the circuit. In other words, when the alternating current is applied to the winding, an EMF of constant magnitude and polarity is created. This EMF in turn induces a current flow through the winding and the current density is higher at the outer part of the winding than the inner part. This results in the steady and stable circuit.

Because of having a constant inductance and improved energy efficiency, CDR7D28MNNP-220NC has a wide range of applications, including in automotive electronics, power supplies, telecom, networking and computing, consumer electronics, medical engineering and aerospace. Its robust construction and improved operating temperature make it capable of road and industrial applications.

In conclusion, CDR7D28MNNP-220NC is a type of fixed inductors and it works based on Faraday\'s law. It mainly used for filtering and decoupling applications and is suitable for a wide variety of environments up to operating temperature of 125°C and humidity levels of up to 95%.
