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 ≦±30% of initial value, internal resistance of ≦300% of initial specified value and leakage current of ≦ the initial value specified. A snap-in version of the RoHS compliant DA series will be available shortly.
Supercapacitors bridge capacitor-battery gap
The DA series of supercapacitors from Jamicon are now available from 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.
