Kam super capacitors have some performance : 1.Small-size, large capacity, excellent voltage holding. 2, unlike battery, unlimited charge/discharge cycle. 3.Wider temperture range. 4.Ideal for backing up of cmo's.Microcomputers, ram's and the like used in vcr's tuners, tv sets, telephone setsand other. 5.Serial structure, two cell with same characteristics. 6.Low esr, high energy density. 7.The capacity range is from 0.1f-3000f, and the operating voltage of capacitors range from 2.5v-5.5v. 8*13
