PM-5R0H155-R is a PowerStor PM Series supercapacitor designed for pulse power and bridge/hold-up power applications. This horizontal-mount cylindrical device features a nominal capacitance of 1.5F with a working voltage of 5.0V and surge voltage of 5.5V. It offers low ESR of 0.07O at 1kHz (0.10O at 100Hz) and nominal leakage current of 20µA after 100 hours at 5V and 20°C. The supercapacitor operates over a temperature range of -40°C to 60°C (extended range to 85°C at reduced 3.9V working voltage) and has nominal dimensions of 10.5 x 20.8 x 32mm with a typical mass of 5.4 grams. Its EDLC construction with high performance materials provides high energy density and long cycle life, making it ideal for applications requiring reliable backup power or pulse current delivery.
