United Chemi-Con is introducing four new snap mount aluminum electrolytic capacitor series specifically designed for
higher ripple current capability. These new series include the U91F, U92F, U92L and U92X which also feature very long life,
wide temperature range, high voltage ratings and a variety of case sizes and terminal styles.
The U91F series is a high temperature series with a lifetime rating of 5,000 hours at 105 C. The three U92 series offer a
lifetime rating of 5,000 hours for U92F, 10,000 hours for U92L or 15,000 hours for U92X at 85 C. The rated lifetime for all
these series is measured with the rated ripple current applied.
All the U91/U92 series capacitors are RoHS compliant and are manufactured with or without an end disk in either a
standard Pb-free PVC sleeve or optional PET sleeve. There are two basic types of PC board terminals, snap-in or straight
standoffs. All of the new snap-in series offer 2, 3, 4 or 5 -pin layouts as either standard or optional configurations depending
on case size. Straight standoff terminals, 5 -pin configuration, are available as an option for the larger case diameters.
Please contact United Chemi-Con with any questions about these new snap mount capacitors. Custom designs are also
available upon request.

The U91F series is a high temperature snap-in series specifically designed for higher ripple current
capability. The U91F capacitors have an endurance rating of 5,000 hours at 105 C with the rated
ripple current applied. All the U91F series capacitors are RoHS compliant and available in a variety
of sizes, with or without an end disk, and encased in a standard Pb-free PVC sleeve or an optional
PET sleeve. Snap-in terminals (2, 4 or 5 -pin configurations) are available as standard or optional
styles depending on case size. Straight standoff terminals (5 -pin configuration) are an option for the
40, 45 and 50mm can diameters.
