Key Features

• Capacitance and Voltage: 2.2 mF (2200 µF) rated at 350 V for substantial bulk energy storage in high-voltage DC systems.
• Screw Terminal Package: Radial can with screw terminals provides robust electrical and mechanical connection suitable for industrial assemblies.
• High Ripple Current: Handles 11.9 A at 120 Hz and 16.66 A at 100 kHz, supporting high-frequency ripple and regenerative currents in inverter and servo systems.
• Temperature and Lifetime: Rated for –40 °C to +85 °C with a specified load life of 5000 hours at 85 °C when subjected to rated ripple and DC bias.
• Endurance and Charge–Discharge Durability: Meets endurance requirements after 5000 hours at 85 °C; designed to cope with high-speed charge–discharge loading, including qualification for 50 million charge–discharge cycles specified in the series datasheet.
• Electrical Reliability: Leakage current after 5 minutes is limited to the series specification (not more than 3√V μA or 5 mA, whichever is smaller); insulation resistance greater than 100 MΩ at DC 500 V; withstands AC 2500 V for 1 minute between terminal and bracket per series specifications.
• Polarized Design: Polarized aluminum electrolytic for conventional DC bulk and smoothing use in power electronics.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint: Smaller-sized implementation for the series with physical dimensions L: 8.5 cm × D: 5.1 cm and a seated height up to 3.346 inches, enabling space-conscious system layouts.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and ripple smoothing in inverter-fed supplies and DC link circuits.
• Motor Drive Inverters: Handles high-frequency regenerative voltages and transient charge–discharge events in AC servomotor and inverter systems.
• High-Frequency Power Modules: Supports modules requiring high ripple-current capability and durable charge–discharge performance.

Unique Advantages

• High ripple handling: Rated ripple currents of 11.9 A (120 Hz) and 16.66 A (100 kHz) reduce stress on upstream components and improve overall power-stage stability.
• Long operational life at elevated temperature: 5000-hour load life at 85 °C under rated ripple and DC bias provides predictable long-term performance in industrial environments.
• Robust mechanical termination: Screw terminal mounting ensures secure, low-resistance connections for installations subject to vibration or frequent servicing.
• Designed for fast charge–discharge: Series-level specifications validate suitability for high-speed cycling and regenerative applications, improving reliability in dynamic power systems.
• Regulatory readiness: RoHS compliance simplifies selection for designs targeting restricted-substance requirements.
