Eaton’s XT supercapacitors are unique, ultra-high capacitance devices utilizing electrochemical double layer capacitor (EDLC) construction combined with new, high performance materials. This combination of advanced technologies allows Eaton to offer a wide variety of capacitor solutions tailored to specific applications that range from a few micro-amps use for several days to using several amps for just seconds. The XT series increases the energy density by 15 percent and power density by 20 percent, leading to longer operating life and/or lower cost systems.
