“Compared to the more commonly used water soluble electrolyte, the DA series is constructed with non-soluble electrolyte, which can help increase the withstand voltage per one cell,” explained Andrew Ferrier, Components Bureau. “Typically this size of supercaps is used in battery back-up applications, replacing the need for coin cells.”
Offered in 10 models, the DA series of supercapacitors covers a nominal capacitance range of between 0.47 – 47 F with a ±20% capacitance tolerance at working voltages of 2.5 V. The operating temperature range of the DA series is between -20 and +70 degC. According to Jamicon’s datasheet – after 1000 hours application of rated DC working voltage at +70 degC, the capacitor shall meet the following limits: capacitance change of less than or equal to ±30% of initial value, internal resistance of less than of equal to 300% of initial specified value and leakage current ? initial value specified. As with all components from Jamicon, the DA series is RoHS compliant.
