Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) rated at 400 V DC, suitable for energy storage and smoothing in high‑voltage power stages.
• High Ripple Current — Specified ripple current of 26.3 A at 120 Hz and 36.82 A at 100 kHz to handle heavy AC ripple in inverter and regenerative applications.
• Robust Endurance — Load life rated 5000 hours at 85°C with DC bias plus rated ripple current; capacitance and leakage meet the endurance criteria after test.
• Temperature Range — Operational from −40°C to +85°C for use across a wide range of industrial environments.
• Mechanical & Mounting — Radial can with screw terminals and stud/bolt mount (TE type) for secure mechanical fixation in high‑vibration installations.
• Leakage & Insulation — Leakage current specified as not more than 3√V µA or 5 mA (whichever is smaller) after 5 minutes at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Safety & Voltage Proof — Voltage proof: no abnormality under AC 2500 V for 1 minute between terminal and bracket.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• Industrial Inverters — Energy smoothing and ripple suppression in inverter DC link circuits where sustained ripple current and voltage endurance are required.
• AC Servomotor Regenerative Circuits — Handling high‑frequency regenerative voltages and fast charge/discharge cycles in motor drive systems.
• Power Supplies for Industrial Equipment — Bulk energy storage and filtering in high‑voltage power supplies used in industrial control and automation.
