Electrical Double Layer Capacitor ED-2203e-2 DYNACAP DVS-series For Re-flow Soldering Features Size: 12.5 8.5 mm, compatible with surface mounting and low ESR. High temperature tolerant (-25 to +85 ) and highly reliable. Unlike batteries, safe and high reliability without containing active and hazardous substances. Unlike batteries, excellent charge and discharge characteristics with no chemical reactions. Responds to temperature 260 during the reflow peek. Applications Memory backup for RTC and the others, instantaneous power assist for batteries Specifications Reference, DVS-3R6DT-R Product Name =Rated capacitance symbol 0.047F473 Max. operating voltage (V) 0.1F 104 3.6V.DC 0.22F 224 0.33F 334 Rated Capacitance (F) 0.047F 0.1F 0.22F 0.33F =Additional symbol Internal resistance ( ) 30 at 1 kHz Size D L (mm) 12.58.5 mm Category temperature range -25 +85 ( ) Weight (g) 3.1g Dimensions Unit: mm 3 .2 13 0. 2 0.3 (8. 5) Recommended land pattern size ( 1.2 ) NOTE: Design, Specification are subject to change without notice.
