Features & benefits

• Very high 15,000 µF capacitance at 63 VDC for substantial bulk energy storage and ripple smoothing.
• Low ESR (12 mΩ) and high ripple rating (13.9 A) reduce heating and improve reliability in high‑power applications.
• Robust Ø51×82 mm chassis with 22.2 mm screw terminal spacing for secure high‑current mechanical and electrical connections.
• 18,000‑hour life rating suitable for continuous industrial operation.

Handling & installation notes

• Observe polarity markings; reverse polarity will damage the capacitor.
• Tighten screw terminals to the manufacturer’s recommended torque to avoid terminal or seal damage.
• Provide adequate ventilation or spacing to dissipate heat from ripple losses to meet rated life.
• Consult the KEMET datasheet/ECAD model for exact mechanical drawings, recommended torque, and mounting details.
