Fixed Inductors

Fixed inductors are basic components used for electrical engineering, providing inductive reactance so that AC signals can be blocked or currents can be limited. The 125CDMCCDS-R82MC model is a widely used fixed inductor, and this article will explore its application field and working principle.

Design of the 125CDMCCDS-R82MC

The 125CDMCCDS-R82MC model is a fixed inductor with an inductance range of 15 to 68 milliturns. It is designed for use in low-power applications, with a maximum rated current of 350 mA. Most applications require low impedance, and the 125CDMCCDS-R82MC provides this with a wide range of impedance: from 6.3 to 300 ohms. The 125CDMCCDS-R82MC also features a low noise level of 5 µV measured at 1 kHz. It has a small outline package, measuring 6 x 7.3 millimeters.

Application Field of the 125CDMCCDS-R82MC

The 125CDMCCDS-R82MC is widely used in various applications, from telecommunications and automotive to consumer electronics. Its low power capability makes it suitable for use in mobile phones, digital set-top boxes, and monitors. It can also be utilized in amplifiers, pulse transformers, and modulation circuits. Due to its range of impedance and small outline, the 125CDMCCDS-R82MC is highly suitable for use as a wideband transformer. Additionally, it can be used as a general transformer, an antenna transformer, or a frequency control inductor for oscillators.

Working Principles of the 125CDMCCDS-R82MC

The 125CDMCCDS-R82MC works based on the principle of inductance. It stores energy when current passes through its copper wire windings, creating a magnetic field. When an AC voltage is applied to the inductor, it reacts by blocking the positive portion of voltage, allowing only the negative portion of the voltage to pass through. This process creates a steady current flow in the form of a sine wave. The inductor also has an impedance factor, providing feedback to the AC voltage and affecting the current level.

Conclusion

The 125CDMCCDS-R82MC is a widely used fixed inductor, with various applications from telecommunications to automotive. Its small size and low power consumption make it suitable for a variety of applications, from digital set-top boxes to oscillators. Its working principle relies on creating a steady current flow via magnetic induction, which provides feedback to the AC voltage. The 125CDMCCDS-R82MC is an essential component for any electrical engineering project and its performance is highly valued.
