Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) rated at 500 V DC with ±20% tolerance (120 Hz, 20°C).
• High-Temperature Endurance — Rated for operation up to 105°C with a specified life of 5,000 hours at 105°C under rated ripple conditions.
• High Ripple Current Capability — 8.5 A at 120 Hz (low frequency) and 11.9 A at 100 kHz (high frequency) to handle heavy AC ripple in power circuits.
• Leakage Current — Specified leakage current of 3,140 µA after 5 minutes at rated voltage.
• Mounting & Package — Screw terminal, radial can package with dimensions φ63.5 × 120 mm for secure, low-resistance connections in power assemblies.
• Wide Operating Range — Operates from −40°C to +105°C to accommodate industrial environments.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Inverters — DC-link and smoothing for inverter circuitry in factory automation and drive systems.
• Regenerative Drive Systems — Supports high-frequency regenerative voltages for AC servomotors and similar motor-drive applications.
• High-Speed Charge–Discharge Systems — Engineered to cope with high-speed charge–discharge loading encountered in energy-buffering and pulsed-power circuits.
• Power Supply Assemblies — Robust screw-terminal mounting and high ripple handling make it suitable for industrial power supplies requiring durable DC bulk capacitance.

Unique Advantages

• High-voltage capability in a compact screw-terminal can: 500 V rating combined with a φ63.5 × 120 mm package for space-conscious high-voltage designs.
• Designed for heavy ripple loads: Dual ripple specifications (120 Hz and 100 kHz) provide predictable performance across low- and high-frequency conditions.
• Thermal and lifetime reliability: 105°C rating with a 5,000-hour endurance at rated ripple current supports long-term operation in hot environments.
• Secure mechanical termination: Screw terminals simplify wiring and deliver reliable electrical connections in high-current power assemblies.
• Regenerative-ready behavior: Series-level design considerations for coping with high-speed charge–discharge and regenerative voltage stress make it appropriate for demanding drive systems.
