The U787D series, the industry’s first 150 C aluminum electrolytic, offers a voltage range of 6.3 to

80VDC, high capacitance and high ripple current capability. The U787D series is the optimum

solution for reducing the size, weight and cost of high performance automotive 36V and 42V systems.

These capacitors maintain a continuous 2,000 hour, 150 C load life (8,000 hours at 125 C with the

150 C rated ripple current applied) and are high vibration resistant. The U787D 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 U787D capacitors are not solvent proof. Refer to guidelines and precautions on the website for

usage and installation conditions recommended for United Chemi-Con products.
