UBY
ALUMINUM ELECTROLYTIC CAPACITORS
High Temperature Range,
For +125°C or 135°C Use
Higher capacitance and higher ripple current than UBT and UBW.
Ideal for automobile control ciucuits such as electric power steering
and direct injection engine drive.
Compliant to the RoHS directive(2011/65/EU).

Marking
After storing the capacitors under no load at 125˚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.
Black print on the case top.
The UBY series places emphasis on high ripple current, as a result the lifetime calculation is different than other series.
