Capacitors are composed of two electrically conductive material layers (electrodes) separated by a dielectric material (or insulator). Capacitors store energy in an electric field generated by this arrangement once a current is supplied to charge the capacitor. In an aluminum electrolytic capacitor, the electrodes are made out of aluminum foil. Between the two aluminum electrodes is a conductive liquid, called an electrolyte. Through an electrochemical reaction, an oxide layer is built upon one of the electrodes (the anode), which serves as the dielectric in an aluminum electrolytic capacitor. Relative Parameters Rated voltage: 25V. Dielectric material: aluminum electrolytic. Product shape: cylindrical. Power characteristics: medium power. Lead type: radial lead wire. Tolerance: ±20%. Operating temperature: -40℃~+105℃. Electrical Characteristics Large Capacitance Aluminum electrolytic capacitors offer a large amount of capacitance per unit of volume for a given voltage rating. The biggest advantage of aluminum electrolytic capacitors is that the electrolytics have high volumetric efficiency, i.e., a higher capacitance per volume than any commonly available capacitor. Aluminum electrolytics are often the only possible solution for certain applications. When selected and designed into the circuit properly, this advantage can be maximized. High Voltage Rating Aluminum electrolytic capacitors can be used in a wide variety of applications. Another advantage of aluminum electrolytic capacitors is the availability of high voltage ratings. Aluminum electrolytic capacitors with a DC voltage rating of 600V are readily available, meaning they can be used in a wide variety of applications. Energy Storage Aluminum electrolytic capacitors have a large capacitance and high voltage rating, meaning high-energy storage capabilities. Considering both the high capacitance and high voltage of aluminum electrolytics together produces another big advantage: energy storage. The energy stored in a capacitor is given by the following equation: U = \frac {1}{2} CV^2 Equation 1. Energy stored in a capacitor (U = Joules, C = Capacitance, V = Voltage) The energy stored in a capacitor increases linearly with capacitance and exponentially with voltage.
