Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance rated at 400 V for bulk energy storage in high-voltage power rails.
• Screw-Terminal Mounting — Radial can with screw terminals for robust, low-resistance electrical and mechanical connections in high-current applications.
• High Ripple Current — Rated ripple current of 26.3 A at 120 Hz and 36.82 A at 100 kHz to support high-frequency and high-current load conditions.
• Load Life — 5000 hours at 85°C under rated ripple current, providing extended operational durability in thermal stress environments.
• Wide Operating Temperature — Specified for use from −40°C to +85°C to accommodate a broad range of industrial ambient conditions.
• Polarized — Polarized design for DC bus and energy-storage applications where correct polarity is required.
• Robust Electrical Safety Characteristics — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute with no abnormality.
• Endurance & Charge–Discharge Reliability — Meets endurance criteria after DC bias plus rated ripple current for 5000 hours at 85°C; charge–discharge endurance test defined for 50 million cycles (ΔV = rated voltage × 0.3 at 3 Hz).
• Compact Can Size — φ90 × 90L profile with package case described as radial can with screw terminals (L: 9 × D: 9 cm), offering a compact footprint for its capacitance and voltage class.
• RoHS Compliant — Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing for high-voltage DC rails in industrial-grade power supplies.
• Inverter Circuits — DC-link and regenerative circuits in inverter designs where high ripple currents and charge–discharge handling are required.
• AC Servomotor Drives — Support for high-frequency regenerative voltages and rapid charge–discharge demands in motion-control systems.
• High-Frequency Power Electronics — Applications needing stable capacitance and low impedance across temperature and frequency ranges up to 100 kHz.

Unique Advantages

• High ripple-current capability: Specified at 26.3 A (120 Hz) and 36.82 A (100 kHz), enabling reliable operation under heavy AC ripple and high-frequency switching conditions.
• Long load life at elevated temperature: 5000 hours at 85°C under rated ripple current supports sustained performance in demanding industrial environments.
• Designed for high-speed charge–discharge: Series characteristics and charge–discharge endurance testing (50 million cycles at ΔV = 0.3×Vrated) indicate suitability for frequent energy cycling.
• Solid electrical safety margins: Insulation resistance and voltage proof specifications (DC 500 V insulation resistance >100 MΩ; AC 2500 V voltage proof) reduce risk of terminal-to-bracket failure modes.
• Secure screw-terminal connections: Radial can with screw terminals simplifies integration into power racks and assemblies while maintaining low-resistance termination.
• RoHS compliance: Conforms to applicable RoHS directives for environmentally restricted substances.
