The U767D series, the industry’s standard 125ꢀC aluminum electrolytic, offers a wide voltage range,
long life, high capacitance and high ripple current capability. These U767D series capacitors allow the
designer to reduce the size, weight and cost of high performance automotive 36V and 42V systems.
These capacitors maintain a continuous 3,000 hour, 125ꢀC load life (12,000 hours at 105ꢀC with the
125ꢀC rated ripple current applied) and are high vibration resistant. The U767D capacitors are
available in either the standard three lead (keyed polarity) radial vertical mounting or the optional low
profile three formed lead horizontal mounting style. Custom designs are available upon request.
The U767D capacitors are not solvent proof. Refer to guidelines and precautions on the website for
usage and installation conditions recommended for United Chemi-Con products.
