Key Features

• Capacitance & Voltage: 6800 µF (6.8 mF) nominal capacitance with a rated voltage of 350 V and ±20% tolerance.
• Screw terminal mounting: Radial can with screw terminals provides secure, low‑impedance connections suitable for high current applications.
• High ripple‑current capability: Rated ripple current of 20.3 A at 120 Hz and 28.42 A at 100 kHz, supporting high‑frequency and regenerative workloads.
• Elevated temperature endurance: Load life specified as 5000 hours with application of rated ripple current at 85°C; designed to meet endurance criteria after DC bias plus ripple application.
• Wide operating temperature: Specified operating range from −40°C to +85°C for broad industrial use.
• Leakage and insulation specifications: Leakage current limited per datasheet formula (after 5 minutes) and insulation resistance ≥100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute between terminal and bracket.
• Compact package dimensions: Package dimensions L: 13.5 cm × D: 6.35 cm with screw‑terminal can format for space‑conscious designs.
• RoHS compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverters: Bulk and smoothing capacitance in inverter power supplies for motor drives and industrial converters.
• AC servomotor regenerative circuits: Handles high‑frequency regenerative voltages and repeated charge/discharge cycles in servo and drive systems.
• High‑frequency switching power supplies: Supports high ripple currents and fast charge/discharge behavior in switching and regenerative power topologies.

Unique Advantages

• High ripple current handling: Specified ripple currents at both low and high frequencies enable reliable operation under heavy AC loading and regenerative conditions.
• Designed for long life at elevated temperature: 5000‑hour load life at 85°C under rated ripple current provides predictable aging and maintenance intervals.
• Screw‑terminal mechanical robustness: Secure terminal connections minimize contact resistance and simplify integration into power assemblies.
• Compact, high‑energy density format: Smaller-sized construction relative to other series in the family delivers large capacitance in a reduced footprint.
• Measurable insulation and voltage proof performance: Insulation resistance and AC voltage proof specifications support safe integration into high‑voltage assemblies.
• RoHS compliance: Meets applicable RoHS directives for environmental regulatory needs.
