Product Details

U91 / U92 Series

High Ripple Snap Mount Capacitors


Table of Contents

Welcome to United Chemi-Con... 


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.

U91F Series

36.jpg


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 configuration s ) 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.

The following specifications shall be satisfied when the capacitors are restored to 20 C after subjecting them to DC voltage for 5,000 hours at   105 C with the rated ripple current applied. The sum of the DC voltage and peak AC voltage must not exceed the full rated voltage of the capacitors.

Capacitance change: ≤ 20% of initial measured value 

Tan ( DF): ≤ 200% of initial specified value 

Leakage current : ≤ initial specified value

Shelf Life

The following specifications shall be satisfied when the capacitors are restored to 20 C after exposing them for 1,000 hours at 105 C without voltage applied. The rated voltage shall be applied to the capacitors for a minimum of 30 minutes, at least 24 hours and not more than 48 hours before the measurements. 

Capacitance change: ≤ 20% of initial measured value 

Tan ( DF): ≤ 150% of initial specified value
