FW SERIES

      The FW series is designed as aluminum electrolytic capacitors.
      FW series features is that it would be adapted to the RoHS directive (2002/95/EC). That is the main one.
      Some important specifications of FW series have been concluded into several points as follow. The first one is about its category temperature range which would be from 40 to +85°C. The next one is about its rated voltage range which would be from 6.3V to 100V. The next one is about its rated capacitance range which would be from 0.1F to 33000F. The next one is about its capacitance tolerance which would be ± 20% at 120Hz, 20°C. The next one is about its leakage current which would means after 1 minute's application of rated voltage, leakage current is not more than 0.03 CV or 4 (A) , whichever is greater and after 2 minutes' application of rated voltage, leakage current is not more than 0.01 CV or 3 (A) , whichever is greater. The next one is about its tan which would be max 0.28 at 6.3V and 0.24 at 10V and 0.20 at 16V and 0.16 at 25V and 0.14 at 35V and 0.12 at 50V and 0.10 at 63V and 0.08 at 100V. For capacitance of more than 1000F, add 0.02 for every increase of 1000F. And measurement frequency is 120Hz, temperature is 20°C. The next one is about its endurance which would means after 2000 hours' application of voltage at 85°C, capacitors meet the characteristic requirements listed at right. The next one is about its shelf life which would means after sroring the capacitors under no load at 85°C for 1000 hours, and after performing voltage treatment based on JIS C 5101-4 clause 4.1 at 20°C, they will meet the specified value for endurance characteristics listed above. The last one is about its marking which would means printed with black color letter on gold sleeve. And so on. For more information about FW series please contact us.
