REQUIREMENTS
After loading the capacitor for the specified time at maximum
category temperature Tmax. = 85 °C and 85 % relative humidity,
and derated permissible maximum operating voltage U = 2.3 V,
following parameters are valid within a timeframe of 1000 h:
(1)
PROCEDURE
(quick reference)
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.
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 UR. Capacitor is charged to the rated voltage at 20 °C. Leakage current is the current at specified
time that is required to keep the capacitor charged at the rated voltage.
After loading the capacitor for specified time at maximum category temperature Tmax. = 85 °C and derated
permissible maximum operating voltage U = 2.3 V, following parameters are valid within a timeframe of
1000 h:
Capacitance
Within ± 30 % of minimum initial specified value
ESR
Less than 3 x initial specified value
Leakage
Within specified value
After loading the capacitor for specified time at maximum category temperature Tmax. = 85 °C and derated
permissible maximum operating voltage U = 2.3 V, following parameters are valid within a timeframe of
2000 h:
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:
Capacitance
Within ± 30 % of minimum initial specified value
ESR
Less than 3 x initial specified value
Leakage
Within specified value
Stored uncharged at 20 °C.
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
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
Ed [Wh/kg] = ½ x C x (UR)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
capacitors in supplementary document.
For printed circuit board cleaning apply non-aggressive cleaning agents only.
For details refer to cleaning requirements for aluminum electrolytic capacitors in supplementary document.
Do not expose capacitors to
• temperatures outside specified range
• high humidity atmospheres; except series 225 which is ruggedized for high humidity 85 °C and 85 % RH
• corrosive atmospheres, e.g. halogenides, sulphurous or nitrous gases, acid or alkaline solutions, etc.
• environments containing oil and grease
