EDC473Z5R5V

PRELIMINARY Type EDC, Long Life Electric Double Layer Supercapacitor Type EDC electric double layer supercapacitors offer high capacitance values in a thru hole stacked coin type package. Primarily designed for integrated circuit voltage backup, the capacitors can also be used to deliver the initial power from batteries. Highlights - Long life - High discharge current - 70 ºC Operating temperature Specifications Operating Temperature Range –25 ºC to +70 ºC Rated Voltage Range 5.5 Vdc to 6.3 Vdc Capacitance Range 0.047 F to 1.5 F Life, Moisture and Temperature Characteristics After the following procedures have been performed, measure the capacitance and ESR at +20 ºC. Life Test: Apply the max. operating voltage for 1000 h at +70 ºC Capacitance Change ±30% of the initial measured value ESR ≤ 4 times the initial specified value Shelf Life: Subject the capacitor to 1000 hours without voltage at +70 ºC. Capacitance Change ±30% of the initial measured value ESR ≤ 4 times the initial specified value Moisture Resistance: Subject the capacitor to 240 hours at +40 ºC at 90 to 95% RH without voltage. Capacitance Change ±30% of the initial measured value ESR ≤ 3 times the initial specified value Temperature Cycling Stabilize the capacitor at each of the following temperatures for 1 hour in sequence, and then measure the capacitance and ESR at that temperature. 1. +20 ºC 2. -25 ºC 3. +20 ºC 4. +70 ºC 5. +20 ºC Capacitance Change (at -25 ºC) ESR (at -25 ºC) Capacita...
