Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) rated at 350 V for energy storage and filtering in high-voltage power stages.
• Screw Terminal Mounting — Radial can package with screw terminals for secure electrical connections and robust mechanical mounting.
• High Ripple Current — Rated ripple current of 13.3 A at 120 Hz and 18.62 A at 100 kHz to handle high-frequency and high-current ripple loads.
• Load Life — Specified endurance of 5000 hours with DC bias plus rated ripple current at 85°C, with limits on capacitance change, tan δ, and leakage current after testing.
• Wide Operating Temperature — Operational range from −40°C to +85°C to support industrial environments.
• Robust Electrical Safety Parameters — Insulation resistance above 100 MΩ (DC 500 V between terminal and bracket) and withstands AC 2500 V for 1 minute between terminal and bracket.
• Compact Mechanical Footprint — Physical size L: 9.5 × D: 5.1 cm with a radial can and screw-terminal bracket configuration suitable for dense power assemblies.
• Charge–Discharge Endurance — Qualified for 50 million charge–discharge cycles (ΔV = rated voltage × 0.3, 3 Hz) with specified retention of capacitance, tan δ and leakage characteristics.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current not more than 3√V (µA) or 5 mA, whichever is smaller (at 20°C).

Typical Applications

• Industrial Inverters — Energy storage and smoothing in inverter power supplies where high ripple handling and 350 V rating are required.
• AC Servo Drives — Supports high-frequency regenerative voltage and rapid charge–discharge cycles encountered in servomotor drives.
• Power Conversion Systems — Filtering and bulk capacitance for high-voltage DC link stages in industrial power electronics.

Unique Advantages

• High ripple tolerance: Explicit ripple current ratings at 120 Hz and 100 kHz make it suitable for both low- and high-frequency ripple environments.
• Long deployed life under load: 5000-hour load-life rating at 85°C provides predictable aging and maintenance scheduling for industrial systems.
• Designed for frequent cycling: Qualification for 50 million charge–discharge cycles supports applications with high-speed charge/discharge demands.
• Secure, serviceable connections: Screw-terminal termination simplifies installation and replacement in field-serviceable power racks.
• Electrical robustness: High insulation resistance and AC voltage proofing improve safety margins between terminal and bracket.
• RoHS compliant: Meets the RoHS directive (2011/65/EU, (EU)2015/863) for regulatory conformance in many industrial markets.
