Type EDC, 70 ºC Long Life Electric Double Layer Supercapacitor
Type EDC, 70 ºC 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

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) ±30% of the initial measured value
ESR (at -25 ºC) ≤ 5 times the initial measured value
Capacitance Change (at +85 ºC) ±30% of the initial measured value
ESR (at +85 ºC) ≤ 4 times the initial measured value
Capacitance Change (Step 5 at +20 ºC) ±10% of the initial measured value
ESR (Step 5 at +20 ºC) meets the initial specified value
