Fixed inductors are electronic components that are used to create inductive circuits. The primary function of a fixed inductor is to store energy in a magnetic field as a result of an electric current flowing through its windings. The most common type of fixed inductors is the air-core inductor where there is no magnetic material inside them. Fixed inductors are mainly used in the audio band pass filter, high frequency transformer, impedance matching, oscillation circuits, reactive components, etc. One type of fixed inductor is the CDR125-821MC.

The CDR125-821MC is a type of fixed inductor that was developed by TDK. It is a compact, high-power, high-current, and high-efficiency inductor. This inductor is designed for use in power and amplifier circuits and in applications that require a low level of noise and ripple. It can also be used in applications that require a high level of frequency stability. The CDR125-821MC is rated for a current of 3A and a power rating of 0.3W. It has an inductance value of 0.25uH and a capacitance value of 0.0002uF. The inductor is also RoHS compliant and its operating temperature range is from -40°C to +105°C.

The working principle of the CDR125-821MC is simple and straightforward. The inductor consists of a coil of wire wound on a core of magnetic material such as iron. When an electric current is applied to the winding, a magnetic field is generated. This magnetic field induces an electromotive force in the coil which produces a voltage. The generated voltage opposes the applied current and this is known as the inductor\'s inductive reactance.

The CDR125-821MC can be used in a variety of applications. It can be used in switch-mode power supplies, AC adapters, DC/DC converters, servo amplifiers, PFC circuits, and electronic ballasts. It can also be used in high-frequency transformers, audio band pass filters, and impedance matching circuits.

To sum it up, the CDR125-821MC is a type of fixed inductor that was developed by TDK. It is a compact, high-power, high-current, and high-efficiency inductor that is rated for a current of 3A and a power rating of 0.3W. The working principle of this inductor is based on the generation of a magnetic field in a coil of wire when an electric current is applied to the winding. The CDR125-821MC can be used in a variety of applications such as switch-mode power supplies, AC adapters, DC/DC converters, servo amplifiers, PFC circuits, electronic ballasts, etc.
