[AR] Using a different technology than diodes, FlatLite is an electroluminescent light source that uses Light-Emitting versions of these devices. An incorrect electrolyte formula can cause failure of these devices on motherboards known as its eponymous plague. The inverse of this devices quality factor is known as tan-delta. Reservoir types of these devices are used in power supplies to smooth the output of a full or half wave rectifier. The limit on the power density of these devices is based on the breakdown voltage of the dielectric employed. A precursor to this modern device is known as a Leyden jar. Capable of storing energy between two conducting plates, for 10 points name this electric component whose eponymous SI unit is measured in farads.
