Quick charge and discharge supercapacitors

Jamicon has introduced the DA series of supercapacitors, available in the UK from specialist components distributor Components Bureau. Bridging the gap between capacitors and batteries, these electric double layer capacitors (EDLCs) are suitable for quick charge and discharge applications.

Offered in 10 models, the DA series is RoHS compliant and covers a nominal capacitance range of between 0.47 and 47F with a ±20% capacitance tolerance at working voltages of 2.5V. The operating temperature range of the DA series is between -20 and 70°C.

After 1000 hours application of rated DC working voltage at 70°C, Jamicon claims the capacitor will meet the following limits: capacitance change of less than or equal to ±30% of initial value, internal resistance of less than or equal to 300% of initial specified value and leakage current of less than or equal to the initial value specified.
