PowerStor® X Series Ultra-Low ESR Supercapacitors

Cooper Bussmann 300 and 400 farad XB and XV series deliver reliability with the longest life available for high-power supercapacitors

The XB series from Cooper Bussmann delivers a technology designed to last for an application’s lifespan. Ultra-low ESR and high capacitance supply pulse power, making other energy sources more efficient. The 20-year operating life and broad temperature range results in the lowest total cost of ownership for an energy device.

The XV series from Cooper Bussmann PowerStor 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 Cooper Bussmann to offer a wide variety of capacitor solutions tailored to specific applications. Effective operation ranges from a few micro-amps for several days to several amps for milliseconds.
