BPA series

      BPA series which are designed for all applications with unknown/reversing polarity are Non-Polar Axial Lead Aluminum Electrolytic Capacitors.
      RLS series have four features.The first one is about audio coupling.The second one is about crossover networks.The third one is that capacitance range of BPA series is from 0.47 F to 1000 F.The last one is that voltage range of BPA series is from 16 WVDC to 100 WVDC.The following is about specification of BPA series.Capacitance tolerance would be within ±20% at 120Hz and 25.Operating temperature range should be -40 to +85. Dissipation Factor at 120Hz and 25°C is as follows.When WVDC is 16 tan should be 0.22.When WVDC is 25 tan should be 0.20.When WVDC is 50 tan should be 0.14.When WVDC is 100 tan should be 0.10.Leakage current should be less than 0.05 CV or 3A whichever is greater when WVDC is 100 WVDC and times are 5 minutes.When temp is -25/ +20 impedance ratio(Max.) at 120 Hz should  respevtively be 2,2,2 and 2 corresponding to WVDC are 10,16,25,35 and 50.When temp is -40/ +250 the corresponding impedance ratio (Max.)at 120 Hz should  respevtively be 6,5,4 and 3.Load life should be 2,000 hours at 85 with rated voltage reversing polarity every 250 hours when capacitance change < 20% of initial measured values,dissipation factor < 200% initial specified value and leakage current < Initial specified value.Shelf life should be 1000 hours at 85°C with no applied voltage.Units will meet load life specification.
