Table 4 RUGGEDIZED FOR HIGH HUMIDITY - BIASED HUMIDITY TESTING PARAMETER PROCEDURE (AT RATED VOLTAGE) REQUIREMENTS
After loading the capacitor for the specified time at maximum category temperature Tmax. = 85 °C and 85 % relative humidity, Humidity (relative) 85 % and derated permissible maximum operation voltage U = 2.6 V, following parameters are valid within a timeframe of 1000 h:  No visible damage No leakage of electrolyte Temperature 85 °C C/C: within ± 30 % of minimum initial specified value ESR: less than 3 x initial specified value Leakage: less than initial specified value
TEST PROCEDURES AND REQUIREMENTS (1) PROCEDURE NAME OF TEST (quick reference)
Capacitance CR and ESRDC Measured by DC discharging method as described in “Measuring of Characteristics”. (2) Non-repetitive current for maximum 1 s at specified operating temperature. Maximum operating voltage (refer to derating table) must not be exceeded. Maximum peak current Usually to be tested with constant current discharge from UR to 0.5 x UR.  Maximum current should not be used in normal operation and is only provided as reference value. Measured at U Leakage current I R. Capacitor is charged to the rated voltage at 20 °C. Leakage current is the current at specified L time that is required to keep the capacitor charged at the rated voltage. After loading the capacitor of specified time at maximum category temperature Tmax. = 85 °C and derated permissible maximum operating voltage U = 2.6 V, following parameters are valid within a timeframe as specified in Table 3: Endurance Capacitance Within ± 30 % of minimum initial specified value ESR Less than 3 x initial specified value Leakage Within specified value After loading the capacitor of specified time at maximum category temperature Tmax. = 85 °C and derated permissible maximum operating voltage U = 2.6 V, following parameters are valid within a timeframe as specified in Table 3: Useful life Capacitance Within ± 50 % of minimum initial specified value ESR Less than 4 x initial specified value Leakage Within specified value After loading the capacitor of specified time at maximum category temperature Tmax. = 85 °C and without charge and under 40 % RH, following parameters are valid within a timeframe of 1000 h: Storage at upper Capacitance Within ± 30 % of minimum initial specified value category temperature ESR Less than 3 x initial specified value Leakage Within specified value Stored uncharged at 20 °C. Shelf life Parameter within initial specification Cycles at 20 °C between rated voltage and half of rated voltage UR with constant current and 1 s rest between charge and discharge: > 500 000 cycles Cycle life Capacitance Within ± 30 % of minimum initial specified value ESR Less than 3 x initial specified value E [Wh] = ½ x C x (UR)2 x 1/3600 Stored energy E, Ed [Wh/kg] = ½ x C x (U specific energy Ed and Ev R)2 x 1/3600 x 1/mass Ev [Wh/L] = ½ x C x (UR)2 x 1/3600 x 1/volume Hand or wave soldering allowed. For details refer to soldering requirements for radial aluminum electrolytic Soldering capacitors in supplementary document. For printed circuit board cleaning apply non-aggressive cleaning agents only. Cleaning For details refer to cleaning requirements for aluminum electrolytic capacitors in supplementary document. Do not expose capacitors to • temperatures outside specified range Environmental conditions • high humidity atmospheres • corrosive atmospheres, e.g. halogenides, sulphurous or nitrous gases, acid or alkaline solutions, etc. • environments containing oil and grease
