The 220 EDLC ENYCAP™ electrical double-layer capacitors from Vishay Intertechnology provide a high-capacitance store of energy which is robust and may be quickly charged and discharged.
The devices are available in ‘Power’ and ‘Energy’ versions. The Power versions can provide higher peak currents up to 35A at 65°C. In the Energy versions the maximum peak current is 25A.
The Energy versions have lower maximum leakage-current ratings. In the 15F Energy version of the 220 EDLC, for instance, maximum leakage current is 6mA 30 minutes after charging, whereas in the 15F Power product this value is 8mA.
The 220 EDLC ENYCAP is rated for operation at 2.7V at up to 65°C. Operation at up to 85°C is possible at an operating voltage of 2.3V. The capacitors’ useful life is more than 10 years when operated at a temperature of 20°C, and they can withstand more than 500,000 charge/discharge cycles.
