Description
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)
