Page 1 Document number: Datasheet: 325F ULTRACAPACITOR CELL. 1. Surge Voltage VR. Absolute maximum voltage, non-repetitive. Duration not to exceed 1 second. I= t / C + ESRDC. 2. Typical values represent mean values of production sample. where t is the discharge time (sec); t = 1 sec in this case. 3. Rated capacitance & ESRDC (measure method) The stated maximum peak current should not be used in normal operation capacitance : Constant current charge (10 mA/F) to VR, 5 min hold at VR, and is only provided as a reference value. constant current discharge 10 mA/F to in case of 325F cell, 10 * 325 = 3,250 mA 6. Energy & Power (Based on IEC 62391-2). ESRDC: Constant current charge (10 mA/F) to VR, 5 min hold at VR, constant CVR2.

4 Current discharge (40 * C * VR[mA]) to V. Maximum Stored Energy, Emax(Wh) = 3,600. in case of 325F cell, charge with 10 * 325 = 3,250 mA and discharge Emax with 40 * 325 * = 35,100 mA Gravimetric Specific Energy (Wh/kg) = mass Usable Specific Power (W/kg) = ESRDC x mass Impedance Match Specific Power (W/kg) = ESRDC x mass Presented Power and Energy values are calculated based on Rated capacitance & Rated (Max.) ESRDC, Initial values. 7. Cycle Life Test Profile Cycle life varies depending upon application-specific characteristics. Actual I x (t2-t1) V results will vary. C= V1-V2 ESRDC =. I. where C is the capacitance (F); 8. Temperature Rise at Constant Current I is the absolute value of the discharge current (A); T=IRMS2 x ESRDC x Rth VR is the rated voltage (V);. V1 is the measurement start voltage, VR (V); where T: Temperature rise over ambient ( C). V2 is the measurement end voltage, VR (V); IRMS: Maximum continuous or RMS current (A).

5 T1 is the time from start of discharge to reach V1 (s); Rth: Thermal resistance, cell to ambient ( C/W). t2 is the time from start of discharge to reach V2 (s); ESRDC: Rated (Max.) ESRDC( ). ESRDC is the DC-ESR ( ); (Note: Design should consider EOL ESRDC for application temperature rise V is the voltage drop during first 10ms of discharge (V). evaluation.).
