PB-5R0V474-R is a cylindrical pack supercapacitor from Eaton's PowerStor Aerogel series, designed for energy storage applications requiring high capacitance in a compact form factor. This vertical-mount device features a nominal capacitance of 0.47 F with a maximum working voltage of 5.0 V and surge voltage of 6.0 V. It offers a low equivalent series resistance (ESR) of 1.0 O measured at 100 Hz and a nominal leakage current of 7 µA after 72 hours at +20 °C. The supercapacitor operates over a temperature range of -25 °C to +70 °C, extended to +85 °C, with nominal dimensions of 8.5 x 16.8 x 14.0 mm and a typical mass of 2.4 grams. Common applications include bridge or hold-up power, memory backup, and battery swap out scenarios where reliable energy storage with long cycle life is essential.
