U767D
The U767D series, the industry’s standard 125 C aluminum electrolytic, now offers extended voltage
ratings and longer life in addition to the higher capacitance and ripple current per case size. These
improved U767D series capacitors allow the designer to reduce the size, weight and cost of
high performance automotive 36V and 42V systems. New ratings offer all these attributes while
maintaining a continuous 3,000 hour-125 C load life (12,000 hours at 105 C with the 125 C rated
ripple current applied) and the same high vibration construction. New U767D ratings are available in
either the standard three lead (keyed polarity) radial VG-LL mounting or the new low profile horizontal
mounting VT-FX style. Custom designs are available upon request.
The U767D capacitors are non-solvent proof. Refer to the Mini-Glossary for cleaning guidelines and
recommended cleaning agents that are compatible with United Chemi-Con products.
Summary of Specifications

The following specifications shall be satisfied when the capacitors are restored to 25 C
after subjecting them to the DC rated voltage for 3,000 hours at 125 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.

When ordering, always specify complete catalog number for U767D Series.
Lead Length: LL = Standard.
FX = Formed Lead ( VT style only).
Case Code: See Case Sizes in Tables.
Capacitance Tolerance: M = 20%
Capacitance Value: Expressed in Microfarads. The first two digits are
significant figures, and the third digit indicates the number of zeros
for capacitance of 100 F or more. R indicates the decimal point for
capacitance less than 100 F (e.g. R33 = .33 F; 3R3 = 3.3 F;
33R = 33 F; 331 = 330 F; 332 = 3,300 F; 333 = 33,000 F ).
Lead Configuration: VG = 3 Lead Radial Vertical Mount.
VT = 3 Formed Lead Horizontal Mount.
DC Rated Voltage: Expressed in Volts (e.g. 35 = 35WVDC).
Series Name: Indicates Basic Capacitor Design.
