Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used as energy storage devices due to their high energy density, low cost, and long service life. The 25ZLQ3900MEFC16X25 is a typical aluminum electrolytic capacitor. It is designed with improved ripple current and temperature characteristics, plus low impedance and low ESR, making it suitable for a variety of applications.

Application Field of 25ZLQ3900MEFC16X25

25ZLQ3900MEFC16X25 is suitable for applications where temperature and current fluctuations are high. Examples include power supplies, AC adaptors, equipment used in large-scale communication systems, xDSL modems, switching voltage regulators and all kinds of UPS systems. It is also suitable in applications where high ripple damping is required.

Other than the power supply applications, 25ZLQ3900MEFC16X25 can be used in communications, audio and video equipment, secondary/clandestine monitoring systems, integrated circuits and digital devices.

Working Principle of 25ZLQ3900MEFC16X25

25ZLQ3900MEFC16X25 is an aluminum electrolytic capacitor with a high capacity, high power factor and excellent temperature characteristics. It is composed of an anode oxide film, a dielectric oxide film, a negative electrode and an anode liquid which is composed of a conductive polymer. The anode oxide film is evenly distributed on the inner wall of the medium, and the anode liquid at the bottom is the electrolyte. During operation, the electric field created by the anode oxide film causes electrons to be pulled from the liquid, creating a charge of positive and negative ions in the liquid.

The space between the anode and negative electrode is filled with the electrolyte, which acts as an insulator. When the external power is connected, the electrolyte serves to transfer electrons from the anode to the negative electrode, generating a current. The electrons flow through the liquid and eventually establish a balance between the two electrodes. This current maintains the charge and the capacitor is said to be "stored" the energy.

If the external power is disconnected, the electrons return to the anode, the circuit is broken, and the stored energy is released. During the process, the flow of electrons keeps the charge stored by 25ZLQ3900MEFC16X25 stable, so that the capacitor can be used again. 25ZLQ3900MEFC16X25 is designed with a low ESR, allowing better current handling, higher ripple current and a longer service life.

Conclusion

25ZLQ3900MEFC16X25 is a high quality, low impedance aluminum electrolytic capacitor that is suitable for a variety of applications, including power supplies, communications, audio and video equipment, and digital devices. It is designed with improved ripple current and temperature characteristics, plus low impedance and low ESR, allowing good current handling, higher ripple current and longer service life.
