The Panasonic SD series are stacked coin type electric double layer capacitors (Gold Capacitor). Electric double layer capacitor does not have dielectric but uses a physical mechanism that generates an electric double layer which performs function of dielectric. These stacked coin type capacitors function as a battery and they are ideally suited for applications requiring secondary power source as a back up energy source for microprocessors and solar battery. These gold capacitors realize large capacitance using activated carbon for electrode.
