In summary, EDC/EDS coin cell supercapacitors are an economical solution to satisfying the need for very high capacitance energy storage and low cost. Standard values are available from 0.047 to 1.5 F with a 3.6, 5.5, and 6.3 working V_DC rating. The 10-year, 500,000-cycle operating life exceeds typical end-product life. Unlike batteries, performance does not degrade with each charge/discharge cycle. The very compact size of the EDC/EDS coin cell aids product design flexibility and provides instantaneous backup power for memory circuitry.
