Fixed Inductors refer to all types of inductors that do not have a variable control to alter their inductance. They are general purpose devices commonly used for smoothing, energy storage, and filtering applications in electrical and electronic systems. The CDRH127NP-102MC is a popular fixed inductor from Panasonic specifically designed to meet the high frequency needs of modern electronic circuits. In this article, we will discuss the application field and working principle of the CDRH127NP-102MC.

Application Field

The CDRH127NP-102MC has wide applications, but is particularly suitable for use in portable RF devices where high frequency signals require inductive energy storage. These applications include portable audio/video applications, radio transmissions, and filtering signals for mobile phones. In addition, it is suitable for resonant inductor applications, LC antenna circuits, power supplies, and clock circuits. The output impedance of the CDRH127NP-102MC is low enough that it is still effective in circuits with bypass capacitors or various low ohmic elements.

Working Principle

The CDRH127NP-102MC relies on a basic inductor principle to store electrical energy in the form of a magnetic field. It is made from highly saturated soft ferrite material providing stable inductance over a wide frequency range. As current passes through the coil of the CDRH127NP-102MC, a magnetic field is created around it. The magnitude of this field is proportional to the amount of current passing through the coil. This stored magnetic energy is then released as current when the current flow stops. This is what gives the inductor its energy storing capabilities.

The CDRH127NP-102MC also performs capacitive reactance, which is the product of the slope of the coil’s self-inductance as a function of frequency. This helps to reduce the total harmonic distortion that can occur in an audio signal, reducing interference and background noise. This type of inductor from Panasonic is also known for its excellent ripple current characteristics, helping to reduce the magnetizing current caused by the peak charging current.

Conclusion

The CDRH127NP-102MC is a fixed inductor from Panasonic designed for use in high frequency RF applications. Its wide applications include portable audio/video, radio transmissions, filtering signals for mobile phones, resonant inductor applications, LC antenna circuits, power supplies, and clock circuits. Its special characteristics include low output impedance, excellent ripple current characteristics, and stable inductance over a wide frequency range. With its unique design, the CDRH127NP-102MC proves to be a reliable and effective fixed inductor for electronic circuits and applications.
