Background

Fixed inductors are passive components that store a certain amount of energy in the form of a magnetic field. Fixed inductors are used in many different types of electronic circuits, from power supplies to audio amplifiers. The CDRH127/LD-221MC, manufactured by GAJIMEX, is a type of fixed inductor, consisting of two coils connected to a cylindrical magnetic core.

CDRH127/LD-221MC Application Field and Working Principle

The CDRH127/LD-221MC fixed inductor is designed for use in a range of electrical circuits, including power supplies, transceiver circuits, digital signal circuits and switching circuits. It’s also suitable for use in high-frequency antenna systems. The electrical characteristics of the CDRH127/LD-221MC are important to its application. For example, it has an impedance of 0.1μH ±10%, meaning that it has a nominal inductance of 0.1μH. This can be useful for providing stable and predictable characteristics in the circuit in which it is used.The working principle of the CDRH127/LD-221MC is based on Faraday’s law of induction. This states that when a conductor is placed inside a changing magnetic field, a current is induced in the conductor. In the case of the CDRH127/LD-221MC, two coils of wire are wrapped around the magnetic core, and each coil is connected to a voltage source. When the voltage sources are connected to the coils, a current is induced in each coil, which produces a magnetic field in the core. This magnetic field is what stores the energy in the inductor.

Conclusion

The CDRH127/LD-221MC is a type of fixed inductor that is used in a wide range of electrical circuits. It has good electrical characteristics, such as an impedance of 0.1μH ±10%, and its working principle is based on Faraday’s law of induction. This allows it to store energy in the form of a magnetic field, providing stable and predictable characteristics in the circuit in which it is used.
