ULD2G2R2MPD6TD Capacitors

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, abbreviated as AECs, are a type of capacitor that utilizes aluminum foil as an anode, electrolyte as a cathode, and a dielectric material between them. AECs are widely used in electric circuits due to their good linearity, lower leakage current, low ESR, and high working voltage.

ULD2G2R2MPD6TD application field and working principle

ULD2G2R2MPD6TD is a type of aluminum electrolytic capacitor designed for various applications. It is capable of working up to 50 VDC with a standard electrolyte, while an extended life electrolyte is available and can be used up to 100VDC. Its electrical parameters: capacitance of 2200uF, ripple current of 130mA, rated voltage of 50 VDC, with three levels of capacitance tolerance, 20%, and 25%.

Application field

ULD2G2R2MPD6TD can be used for power supply filtering, power amplification circuit filtering, electromagnetic interference reduction, motor starting, charging and discharging circuits, switching power supply circuit, etc.

Working Principle

AECs consist of an anode made of aluminum foil and an electrolyte solution, a cathode separator paper, and a polarized dielectric. The electrolyte solution penetrates the layers of aluminum during electrolysis and forms a barrier film on the anode. Due to the polarization of the dielectric, the barrier film reduces the capacity of the capacitor and thus the capacitor has a voltage rating. When the voltage on the capacitor reaches the rated voltage, the barrier films is compressed, resulting in a decrease in capacitance and an increase in leakage current.

Conclusion

ULD2G2R2MPD6TD is widely used in power supply filtering, power amplification, electromagnetic interference reduction, etc. Its electrical characteristics make it ideal for these applications. The working principle of AECs is to use an anode of aluminum foil, an electrolyte solution, and a dielectric that is polarized to reduce capacity at higher voltage.
