Key Features

• High capacitance and voltage: 5600 µF nominal capacitance rated at 400 V for bulk energy storage in power electronics.
• Screw terminal package: Radial can with screw terminals for secure, low‑impedance connections in cabinet and chassis installations.
• High‑speed charge–discharge capability: Designed for 85°C high‑speed charge–discharge operation, suitable for regenerative and pulsed power conditions.
• Low ESR and high ripple tolerance: ESR 1.6 mΩ (measured at 120 Hz) with ripple current ratings of 21.4 A at 120 Hz and 29.96 A at 10 kHz, enabling sustained AC ripple handling.
• Endurance and longevity: Rated lifetime of 5000 hours at 85°C under rated bias; endurance of charge–discharge behavior specified to 20 million cycles (ΔV = rated voltage × 0.3, 3 Hz) at room temperature.
• Wide operating range and stability: Operating temperature −25°C to +85°C with capacitance tolerance ±20% and an impedance ratio Z(−25°C)/Z(+20°C) up to 8 for improved low‑temperature performance.
• Leakage current specification: After 5 minutes’ application of rated voltage, leakage current is limited to not more than 3√(V) μA or 5 mA, whichever is smaller, per series specification.
• RoHS compliance: Compliant to the RoHS Directive (2011/65/EU, (EU)2015/863).
• Compact footprint: Physical size documented as L: 13 cm × D: 7.62 cm for board/layout planning in power assemblies.

Typical Applications

• Industrial Motion Control: Energy recovery and smoothing for AC servomotor drives where high‑speed regenerative voltages occur.
• Power Inverters: Bulk DC link and ripple filtering in general inverter designs requiring high capacitance at elevated voltage.
• Rectifier / Voltage Doubler Circuits: DC smoothing and energy buffering in rectifier topologies including voltage doubler arrangements.
• Equipment in Voltage‑Fluctuating Areas: Systems exposed to fluctuating supply conditions that need robust charge–discharge endurance and ripple handling.

Unique Advantages

• High energy density at 400 V: Enables fewer capacitors to achieve required bulk storage for power rails and DC links.
• Low ESR for efficient ripple management: 1.6 mΩ ESR at 120 Hz supports higher ripple currents and reduces thermal rise under AC stress.
• Designed for charge–discharge endurance: Specified to endure 20 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz), improving reliability in regenerative systems.
• Industrial temperature range: −25°C to +85°C operation and specified 5000 h life at 85°C for predictable long‑term performance in demanding environments.
• Secure screw‑terminal mounting: Robust electrical and mechanical connection suited to high‑current power assemblies.
• Regulatory compliance: RoHS conformity supports use in regions with restricted substance requirements.
