NOTES BCAP3400 P285 K04 1. Capacitance and ESRDC measured at 25°C using specified test current in K2 2.7V Series Datasheet. 2. Typical values represent mean values of a production sample. 3. Absolute maximum voltage, non-repeated. Not to exceed 1 second. 4. After 72 hours at rated voltage. Initial leakage current can be higher. 0.12V2 5. Per IEC 62391-2, Pd = ESRDC x mass V2 4 x ESRDC x mass ½ CV2 7. Emax = 3,600 x mass 6. Pmax = 8. Estored = BCAP3400 P285 K05 ½ CV2 3,600 9. ∆T=IRMS2 x ESR x Rca 10. Cycle using specified test current per waveform in K2 2.7V Series Datasheet. 11. Cycle life varies depending upon application-specific characteristics. Actual results will vary. 12. Per United Nations material classification UN3499, all Maxwell ultracapacitors have less than 10 Wh capacity to meet the requirements of Special Provisions 361. When packaged according to the regulation, both individual ultracapacitors and modules composed of those ultracapacitors shipped by Maxwell can be transported without being treated as dangerous goods (hazardous materials).
