Features & benefits

• Very high 10,000 µF capacitance at 63 VDC for demanding bulk energy storage and smoothing in power electronics.
• Low ESR (17 mΩ) and 10.8 A ripple rating reduce heating under ripple conditions and improve system reliability.
• Screw‑terminal construction provides secure connections for high‑current bus wiring and robust mechanical retention.
• 11,000‑hour rated life for continuous industrial applications.

Handling & installation notes

• Confirm polarity before installation.
• Tighten screw terminals to KEMET recommended torque to avoid damage to terminals or seals.
• Ensure adequate ventilation and spacing to dissipate heat generated by ripple current to achieve rated life.
• Verify mechanical clearance for Ø36×82 mm body and 12.8 mm terminal spacing; consult the datasheet/ECAD for precise mounting dimensions.
