Key Features

• High Capacitance: 18,000 µF nominal capacitance for bulk energy storage and smoothing in high-voltage circuits.
• 400 V Rated Voltage: Rated for 400 V operation to support extra-high-voltage industrial power conversion needs.
• High Ripple Current Capability: 33 A at 120 Hz (low frequency) and 46.2 A at 100 kHz (high frequency) to handle heavy AC ripple stress in power supplies and inverters.
• Long Endurance: Rated for 20,000 hours at +85°C under standard ripple conditions, providing sustained performance over long service lifetimes.
• Wide Operating Temperature Range: -25°C to +85°C to accommodate a variety of industrial environments.
• Screw Terminal / Radial Can Package: Robust screw-terminal mounting (φ100 can, nominal M8 bolt) and radial can construction for secure electrical and mechanical connections.
• Leakage Current: Specified leakage current up to 5,000 µA (5 mA), consistent with large, high-voltage electrolytic designs.
• RoHS Compliant: Meets RoHS directive requirements as indicated in the product data.
• Flame-Retardant Electrolyte Option: Flame retardant electrolyte is available for applicable types in the series.
