Features & benefits

  • Extremely high 47,000 µF capacitance at 63 VDC for maximum bulk energy storage and smoothing.
  • Low ESR (8 mΩ) and high ripple rating (26.7 A) minimize internal heating and improve reliability in high‑power applications.
  • Robust Ø66×105 mm chassis with 28.5 mm screw terminal spacing for secure high‑current mechanical and electrical connections.
  • 19,000‑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 prevent terminal or seal damage.
  • Ensure adequate ventilation or spacing to dissipate heat from ripple losses to achieve rated life.
  • Consult the KEMET datasheet and ECAD model for precise mechanical drawings, recommended torque, and mounting details.
