Aluminum electrolytic capacitors are widely used in all kinds of electrical equipment, such as audio and video product, power supply and communication device, computer and information products etc, owing to their low equivalent series resistance (ESR), low equivalent series inductance(ESL) and large capacitance. UMW1E330MDD1TP belongs to aluminum electrolytic capacitor, and its application field and working principle will be explained below.

UMW1E330MDD1TP are mainly used in computers, routers, set-up boxes and other communication and information device. It is characterized with its high volumetric efficiency and very high capacitance in the same package size. The series has wide capacitance range from 1uF to 330uF, high temperature range operating temperature from -40~+105, low dissipation ESR, low insulation resistance and long life span. It is ideal for high-frequency SMT and other OEM applications where high capacitance, high volumetric efficiency, and long-term reliability are essential.

The main structure of UMW1E330MDD1TP capacitor is combination of aluminium oxide anode and etched aluminium surface cathode in aluminum shell, aluminum foil and electrolytic solution. As known from the name, electrolytic solution is the medium which partially forms electric field between anode and cathode. It can be applicable for high voltage and large capacitance.

As for the working principle of UMW1E330MDD1TP, it consists in principle of the two plates which were covered by the aluminum and electrolytic solution for the electrical isolation between the two plates. A positive and negative voltage is applied to respective plates. The positive voltage is applied to the anode and the negative voltage is applied to the cathode. The internal resistance of the capacitor is very low and gets low with increasing voltage. The capacitance also increases with voltage. Furthermore, in case of high frequency and high temperature use, the dielectric strength of the electrolyte also improves.

To summarize, UMW1E330MDD1TP is an aluminum electrolytic capacitor which has wide applicability in computers, routers, set-up boxes and other communication and information device. Its Internal resistance of the capacitor is very low and its capacitance increases with voltage. The working principle is combination of aluminium oxide anode and etched aluminium surface cathode in aluminum shell, aluminum foil and electrolytic solution.
