Cylindrical Supercapacitors

Eaton Cylindrical Supercapacitors feature large capacitance for high energy density and utilize electrochemical double-layer capacitor (EDLC) construction. These supercapacitors combine the EDLC construction with high-performance materials. Options include an automotive grade and snap-in. Eaton Cylindrical Supercapacitors are suitable for various applications such as energy storage, solar capture, RF radio power, backup power, engine starting, medical equipment pulse power, and high-pulse current.
