Key Features

• Capacitance & Voltage: 5.6 mF (5600 µF) nominal capacitance with a rated voltage of 350 V and ±20% tolerance, providing substantial energy storage for DC bus and regenerative applications.
• Screw-Terminal Radial Can: Screw terminal mounting for secure, low-impedance connections in high-current systems; package case described as radial can with screw terminals.
• High Ripple Current Capability: Rated ripple current of 20.4 A at 120 Hz and 28.56 A at 10 kHz, supporting heavy ripple and high-frequency charge–discharge cycles.
• Temperature & Endurance: Operating range −25 °C to +85 °C with endurance specified as 5000 hours at 85 °C under DC bias plus rated ripple current, ensuring reliable performance under elevated temperature stress.
• Charge–Discharge Durability: Designed for high-speed charge–discharge behavior with endurance validated by 20 million cycles (ΔV = rated voltage × 0.3, 3 Hz) at room temperature per datasheet conditions.
• Leakage Current Specification: After 5 minutes at rated voltage and 20 °C, leakage current is limited to not more than 3√V (µA) or 5 mA, whichever is smaller, providing predictable leakage behavior for system design.
• Physical Size: Physical footprint L: 15 × D: 6.35 cm with a maximum seated height of 5.906 inch, enabling compact integration where screw-terminal mounting is required.
• RoHS Compliance: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servomotor Regeneration: Energy buffering and absorption of regenerative currents in motor drives to stabilize the DC bus during braking events.
• General Inverters and Motor Drives: DC link and smoothing capacitor for inverters where high ripple and frequent charge–discharge cycles occur.
• Fluctuating-Voltage Equipment: Systems operating in unstable mains or variable supply conditions that require robust energy storage to maintain DC bus stability.
• Rectifier / Voltage Doubler Circuits: DC smoothing and energy storage in rectifier stages, including voltage-doubler configurations.
• General Purpose Power Electronics: Applications that need large-value, polarized capacitors with secure screw-terminal connections for high-current paths.

Unique Advantages

• High ripple handling: Dual ripple ratings (120 Hz and 10 kHz) enable designers to size the capacitor confidently for both low- and high-frequency ripple environments.
• Robust screw-terminal connection: Screw terminals provide a durable, low-resistance electrical and mechanical connection suited for high-current power assemblies.
• Validated endurance at elevated temperature: 5000 hours at 85 °C under rated conditions gives predictable long-term behavior for industrial installations.
• Designed for rapid charge–discharge cycles: Endurance over 20 million charge–discharge cycles supports high-frequency regenerative systems and frequent cycling use cases.
• Predictable leakage performance: Clear leakage current limit after voltage application simplifies thermal and standby current budgeting in system design.
• RoHS compliant: Meets current RoHS requirements for material compliance in commercial and industrial products.
