Aluminum electrolytic capacitors are components that play an important role in electronic equipment. UTM1E221MHD, a product of the aluminum electrolytic capacitor series, has a wide range of applications in the field of electronic components. This article will discuss the application field and working principle of UTM1E221MHD.

Application field of UTM1E221MHD

UTM1E221MHD is a radial lead type electrolytic capacitor with a capacity of 2.2uF and a rated voltage of 16V, which is mainly applicable to 0.2W/µF type DC audio conversion power supply, audio signal feedback filter, switching power supply filter, DC power filtering, AC high frequency line compensation and other fields.

UTM1E221MHD is an ideal choice for audio filtering applications. The capacitor meets the requirements for impedance stability, ripple suppression and high frequency noise suppression in AC power conversion applications. It is designed for switching power supplies, and its excellent ripple current absorption capacity ensures that the capacitor operates reliably in high frequency AC power supplies. It is mainly used in AC power supply rectifying chopping and frequency conversion filter systems, DC audio power amplifier circuits and other fields.

Working Principle of UTM1E221MHD

The working principle of UTM1E221MHD is: when the external alternating current (AC) power supply generates an alternating electric field (alternating movement of electric charge) on the capacitor\'s two electrodes, the positive and negative electric charges on the electrode simultaneously move in opposite directions to achieve storage. The capacitor mainly uses the polarization of the electrolyte to form a functional interface between the electrode and the electrolyte, and stores electrical energy in a very small volume. Therefore, it can effectively filter out the high-frequency signals of the power supply and convert them into low-frequency signals.

In addition to its use in filtering high-frequency AC signals, UTM1E221MHD is also used in applications where an AC source is rectified and converted to DC power. In this application, the capacitor stores and stores energy and decreases at regular intervals. When the alternating current passes through the capacitor, the voltage is attenuated to 0V, resulting in a pulse current.

UTM1E221MHD can also be used as a feedback capacitor in audio amplifiers. When an audio signal is amplified, the amplifier needs to provide the original signal to the feedback loop to ensure the stability of the amplifier. The capacitor in the feedback loop acts as a low-pass filter, which smooths out the signal and improves the fidelity of the amplified signal.

Conclusion

In summary, UTM1E221MHD is an aluminum electrolytic capacitor with a capacity of 2.2uF and a rated voltage of 16V. Its wide application range includes uses in audio filters, switching power supply filters, DC power filtering, AC high frequency line compensation and audio amplifier feedback circuits. Its working principle relies on the alternation of electric charges on the electrode of the capacitor to store electrical energy, filter out high-frequency signals and convert them into low-frequency signals.
