Type EDLR electric double layer supercapacitors oer 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.

Max. Initial Internal Resistance (ohms at 1kHz)
Life, Moisture and Temperature Characteristics After the following procedures have been performed, measure the capaci-
tance and internal resistance at +20 ºC.
Life Test: Apply the max. operating voltage for 2000 h at +85 ºC
Capacitance Change
Internal Resistance
±30% of the initial measured value at +20 ºC
≤ 2 times the initial specied value
Shelf Life: Subject the capacitor to 2000 hours without voltage at +85 ºC.
Capacitance Change
Internal Resistance
±30% of the initial measured value at +20 ºC
≤ 2 times the initial specied value
Moisture Resistance: Subject the capacitor to 500 hours at +55 ºC at 90 to 95% RH without
voltage.
Capacitance Change
Internal Resistance
±10% of the initial measured value at +20 ºC
meets the initial specied value
Soldering Heat Resistance: Immerse the capacitor leads to within 2 mm of the capacitor body in
solder that is at a temperature of 260 ºC for 10 seconds.
Capacitance Change
Internal Resistance
±10% of the initial measured value at +20 ºC
meets the initial specied value
Temperature Cycling Stabilize the capacitor at each of the following temperatures for 1 hour in
sequence, and then measure the capacitance and internal resistance at
that temperature.
1. +20 ºC
2. -25 ºC
3. +20 ºC
4. +85 ºC
5. +20 ºC
