Aluminum electrolytic capacitors consist mainly of an anode foil, cathode foil, electrolyte, and aluminum oxide film. The anode and cathode foils in an aluminum electrolytic capacitor are usually made from aluminum and are formed into ribbons or foils. Due to the ability of the aluminum foil to absorb the electrolyte, an anodic oxidation layer is formed on the aluminum surface when a voltage is applied. This oxidation layer acts as a dielectric, allowing and storing electrical energy.

UFW1A101MDD is a type of aluminum electrolytic capacitor, specifically a radial-leaded aluminum electrolytic capacitor, with a voltage rating of 100VDC. UFW1A101MDD capacitors are commonly used in power supplies, DC-DC converters, LED lighting, and other similar applications. The rated capacitance of UFW1A101MDD aluminum electrolytic capacitor is 100μF with a tolerance of ±20%. The maximum operating temperature range is -40~100℃.

The working principle of UFW1A101MDD aluminum electrolytic capacitor begins with the anode and cathode foils, which are placed in an electrolytic solution. When a voltage is applied between the two plates, ions from the electrolytic solution carry a current from one plate to the other. This current causes an alloys’ reaction at the anode, which forms an oxide film. This oxide film acts as a dielectric, so that when the voltage is applied, it will accumulate electrical charge. The dielectric strength of the UFW1A101MDD aluminum electrolytic capacitor is determined by the thickness of the oxide film.

The oxide layer provides greater capacitance than a traditional aluminum capacitor, but due to its construction and the oxidation layer, it also has a limited life. The leakage of current in the oxide layer can create heat, which can cause the capacitor to fail over time. To prevent this from happening, UFW1A101MDD aluminum electrolytic capacitors usually have a voltage limit and must not be used at voltages over their specified rating.

The construction of UFW1A101MDD aluminum electrolytic capacitors allows for a wide range of capacitances, voltage ratings and temperature ratings. The construction also eliminates the need for bulky and heavy wires and other materials. Furthermore, the capacitors are relatively low cost, making them ideal for use in many applications, including power supplies, DC-DC converters, LED lighting, and more.
