Description
Eaton supercapacitors are unique, ultra-high
capacitance devices utilizing electrochemical
double layer capacitor (EDLC) construction
combined with new, high performance
materials. This combination of advanced
technologies allows Eaton to offer a wide variety
of capacitor solutions tailored to specific
applications that range from a few micro-amps
for several days to several amps for
milliseconds.

Manual solder
+350 °C, 4-5 seconds. (by soldering iron), generally manual, hand soldering is not recommended.
Reflow soldering
Do not use reflow soldering using infrared or convection oven heating methods.
Cleaning/Washing
Avoid cleaning of circuit boards, however if the circuit board must be cleaned use static or ultrasonic immersion in a standard circuit board
cleaning fluid for no more than 5 minutes and a maximum temperature of +60 °C. Afterwards thoroughly rinse and dry the circuit boards. In
general, treat supercapacitors in the same manner you would an aluminum electrolytic capacitor.
