Electrical Parameters (Must Match Exactly):

  • Capacitance: 10000 µF
  • Voltage Rating: 63 V
  • Tolerance: ±20%
  • ESR @ 100Hz: 43 mOhm
  • Lifetime @ 105°C: 6000 Hrs
  • Ripple Current @ 100 Hz: 8.2 A
  • Ripple Current @ 10 kHz: 11.7 A
  • Impedance: 34 mOhms

Mechanical Parameters (Must Match Exactly):

  • Package Type: Radial, Can - Screw Terminals
  • Lead Spacing: 12.80 mm
  • Diameter: 36.00 mm
  • Height: 64.00 mm (Max)
