LCA series

      LCA series are aluminum electrolytic capacitors with low leakage current.LCA series have three features.The first one is that wide capacitance range of LCA series is from 0.1 to 100 F.The second one is about standard case sizes.The third one is that operating voltage range of LCA series is from 6.3 WVDC to 50 WVDC.
      The following is about specification of LCA series.Capacitance tolerance would be within ±20% at 120Hz and 20.Operating temperature range should be -40 to +85.Dissipation Factor at 120Hz and 20°C is as follows.When WVDC is 6.3 tan should be 0.24.When WVDC is 10 tan should be 0.20.When WVDC is 16 tan should be 0.16.When WVDC is 25 tan should be 0.14.When WVDC is 35 tan should be 0.12.When WVDC is 50 tan should be 0.10.Leakage current should be 0.002 CV or 0.5A whichever is greater under the condition of 2 minutes.When temp is -25/ +20 impedance ratio at 120 Hz should  respevtively be 4,3,2,2,2 and 2 corresponding to WVDC are 6.3,10,16,25,35 and 50.When temp is -40/ +20 the corresponding impedance ratio at 120 Hz should  respevtively be 8,6,4,4,3 and 3.Load life should be 2,000 hours at 85 with rated voltage when capacitance change 25% of initial measured values,dissipation factor 200% initial specified value and leakage current100% Initial specified value.Shelf life should be 1000 hours at 85°C with no applied voltage when capacitance change 20% of initial measured values,dissipation factorinitial specified value and leakage currentInitial specified value.Capacitors placed on a 250°C hot plate for 30 seconds with their electrode terminals facing downward will fulfill the following conditions after being cooled to room temperature.When the frequencies were 50Hz,120Hz,400Hz,1kHz,10kHz and 100kHz,the corresponding Ripple Current Multipliers were 0.8,1.0,1.0and 1.1,1.3 and 1.5.When the temperature respectively, +85,+70 and +65,the corresponding ripple current multipliers were 1.0,1.35 and 1.35.
