1. Capacitance, ESR and Leakage current are all measured according to IEC 62391-1 at +20 °C

2. 15 °C Temperature Rise

3. Peak Current is for 1 second = ½ Working Voltage x Capacitance / (1 + ESR x Capacitance)

4. Leakage current measured after 72 hours, +20 °C

5. Max. Power = Working Voltage2 / 4 / ESR

6. Stored energy = ½ Capacitance x Working Voltage2 / 3600
