Engineered for inverter and regenerative circuits, this capacitor combines high ripple-current capability, a long 5000-hour load life at 85°C, and a wide operating temperature range to support demanding industrial power-supply designs.

Key Features

• Capacitance & Voltage — 8200 µF (8.2 mF) rated at 350 V for bulk energy storage and DC-link applications.
• High ripple-current capability — 24.2 A at 120 Hz and 33.88 A at 100 kHz to support heavy AC ripple and high-frequency regenerative loads.
• Screw terminal / Stud bolt mount — Robust radial can with screw terminals and stud/bolt mounting for secure mechanical and electrical connections in industrial enclosures.
• Temperature & Lifetime — Rated for –40°C to +85°C with a guaranteed load life of 5000 hours at 85°C under rated ripple conditions.
• Compact form factor — φ90 × 90L package (L: 9 × D: 9 cm) provides a smaller-sized solution compared to predecessors while maintaining high performance.
• Polarized design — Standard polarized aluminum electrolytic construction for DC-link and bulk filtering applications.
• Electrical reliability — Insulation resistance >100 MΩ at DC 500 V and voltage proof of AC 2500 V for 1 minute between terminal and bracket.
• Leakage and tolerance — Capacitance tolerance ±20% (120 Hz, 20°C); leakage current after 5 minutes limited to 3√V µA or 5 mA (whichever is smaller).
• Standards compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies — Bulk DC-link filtering and energy storage for inverter circuitry used in industrial drives and power conversion.
• AC servomotor regenerative circuits — Handles high-frequency regenerative voltages and supports rapid charge–discharge cycles common in servo systems.
• High-frequency power electronics — Suitable for designs requiring high ripple-current handling at both low and high frequencies, including general inverters and regenerative power modules.
