• High Ripple Current Capability Rated ripple current up to 15 A at 120 Hz (low frequency) and 21 A at 10 kHz (high frequency) to support effective ripple rejection and thermal stability under real operating loads.
• Screw Terminal Mounting Robust screw-terminal, radial can package enabling secure electrical and mechanical connection for high-current applications.
• Robust Endurance Load life: 5000 hours at 85°C with applied rated ripple current; designed to maintain capacitance within ±20% after endurance testing.
• Leakage and Insulation Specified leakage current of 4110 µA and insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket (per datasheet conditions).
• Mechanical & Packaging Large-format can: φ76.2 mm × 110 mm (diameter × length); supplied in cardboard packing for mass-production handling.
• Environmental Compliance RoHS compliant.

Typical Applications

• General-purpose Power Filtering Bulk energy storage and smoothing in power supplies and converters where 400 V rating and high capacitance are required.
• DC-link Capacitor High ripple current capability supports DC-link use in industrial power electronics and inverter front ends.
• High-Voltage Smoothing Bulk smoothing and transient damping in high-voltage systems that need secure screw-terminal connections and long endurance at elevated temperatures.

Unique Advantages

• High Energy Density at Elevated Voltage: 4700 µF at 400 V provides substantial stored energy per component, reducing the need for multiple parallel devices.
