PowerStor / Eaton PHV Supercapacitors

PowerStor® / Eaton PHV Supercapacitors provide large capacitance for high energy density and ultra-low ESR for high power density. These devices utilize electromechanical double-layer capacitor (EDLC) construction, combined with high-performance materials. PowerStor / Eaton PHV Supercapacitors offer a nominal capacitance range of 0.5 to 5F, maximum working voltage of 5.4V, and an operating temperature range of -40°C to +65°C. Typical applications include pulse power, and bridging or hold-up power.
