ALUMINUM ELECTROLYTIC CAPACITORS
UPW
Miniature Sized, Low lmpedance,
High Reliability For
Switching Power Supplies
Smaller case size and lower impedance than UPM.
Low impedance and high reliability withstanding 2000 hours to 8000 hours.
Capacitance ranges available based on the numerical values in E12 series
under JIS.
Compliant to the RoHS directive (2011/65/EU).

Endurance
The specifications listed at right shall be met when the
capacitors are restored to 20˚C after D.C. bias plus rated
ripple current is applied for 8000 hours (2000 hours for
φD=4,
5 and 6.3, 3000 hours for
φD=8,
5000 hours for
φD=10,
7000
hours for
φD=12.5)
at 105˚C, the peak voltage shall not
exceed the rated voltage.
Capacitance change
Within ±20% of the initial capacitance value
tan
δ
200% or less than the initial specified value
Leakage current
Less than or equal to the initial specified value
Shelf Life
Marking
After storing the capacitors under no load at 105˚C for 1000 hours and then performing voltage treatment based on JIS C 5101-4
clause 4.1 at 20°C, they shall meet the specified values for the endurance characteristics listed above.
