Key Features

• Capacitance & Voltage  6.8 mF (6800 µF) nominal capacitance with a 500 V rated voltage suitable for high-voltage smoothing and energy storage requirements.
• Load Life & Temperature  Specified load life of 5000 hours at 85°C when rated ripple current is applied; operating temperature range is -25°C to 85°C.
• High Ripple Current Capability  Rated ripple currents include 21.2 A at 120 Hz and 29.68 A at 10 kHz, supporting substantial AC ripple handling in power systems.
• Screw Terminal Mounting  Radial can with screw terminals provides secure, low-inductance connections for high-current, high-voltage installations.
• Electrical Reliability  Insulation resistance is specified at more than 100 MΩ at DC 500 V between terminal and bracket; voltage proof test is AC 2500 V for 1 minute between terminal and bracket.
• Capacitance Tolerance & Polarization  Capacitance tolerance ±20% (at 120 Hz, 20°C); polarized device suitable for DC applications.
• RoHS Compliant  Meets the RoHS directive (2011/65/EU, (EU)2015/863).
• Frequency Ripple Coefficients  Frequency coefficients are provided for scaling rated ripple: 50 Hz = 0.80, 60 Hz = 0.82, 120 Hz = 1.00, 360 Hz = 1.20, 1 kHz = 1.35, ≥10 kHz = 1.40.
• Leakage Current Specification  Leakage current after 5 minutes is limited to 3√(C·V) µA or 5 mA, whichever is smaller (C in µF, V in V), measured at 20°C.

Typical Applications

• High-voltage power supplies  Bulk smoothing and energy storage where a 500 V rated capacitor and high capacitance are required to stabilize DC rails.
• Power conversion DC link  DC-link and smoothing capacitors in converters and inverters that require sustained ripple handling and high-voltage capability.
