PWseries
Miniature Sized, Low lmpedance,
High Reliability For Switching Power Supplies
Radial Lead Type Type numbering system (Example : 10V 680µF)
Smaller case size and lower impedance than PM series.
Low impedance and high reliability withstanding 2000 hours to 8000 hours.
Capacitance ranges available based on the numerical values in E12 series
under JIS.
Adapted to the RoHS directive (2002/95/EC).
