• Tolerance: ±20%
• ESR @ 100Hz: 304 mOhm
• Lifetime @ 85°C: 11000 Hrs
• Operating Temperature Range: -40°C ~ 85°C
• Ripple Current @ 100 Hz: 3.1 A
• Ripple Current @ 10 kHz: 6.9 A
• Impedance: 172 mOhms

Mechanical Parameters (Must Match Exactly):

• Lead Spacing: 12.80 mm
• Diameter: 36.00 mm
• Height (Seated Max): 54.00 mm
• Package Type: Radial, Can - Screw Terminals
