Key Features

• High Capacitance & Voltage: 680,000 µF (680 mF) nominal capacitance at a 16 V rated voltage, providing substantial bulk energy storage and smoothing in DC systems.
• High Ripple Current Capability: Low-frequency ripple current of 33 A (120 Hz) and high-frequency ripple current of 37.95 A (100 kHz), enabling effective ripple handling across a broad frequency range.
• Endurance & Temperature Range: Rated for 5000 hours at 85°C endurance and an operating temperature range of −40°C to +85°C for sustained performance in elevated-temperature environments.
• Loss Characteristic: Tangent of loss angle (tan δ) of 1.5 measured at 20°C and 120 Hz, specified for electrical loss assessment.
• Leakage Current & Tolerance: Specified leakage current up to 5000 µA and capacitance tolerance of −20% to +20% at 120 Hz, 20°C.
• Mechanical & Mounting: Screw terminal mounting in a radial can package (φ90 × 170 mm body), providing secure, serviceable connections and easy installation.
• Manufacturing & Compliance: Cardboard packing, RoHS compliant, and listed as mass production status for stable availability.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy storage in high-capacitance DC link and output filter stages where sustained ripple handling is required.
• Power Conversion & Inverters: DC bus and intermediate storage for converters and inverters that demand high capacitance and high ripple-current capability across frequencies.
• Uninterruptible Power Systems (UPS): Bulk energy reservoir for ride-through periods and large transient filtering in UPS and standby power systems.
• Energy Storage & Conditioning: Large-capacitance smoothing for regenerative systems and energy conditioning modules that require durable screw-terminal connections.

Unique Advantages

• Substantial Bulk Capacitance: 680,000 µF reduces the need for multiple parallel devices, simplifying BOM and board space planning for large-energy designs.
• Robust Screw-Terminal Connections: Screw terminals enable secure, serviceable electrical connections suitable for high-current bus implementations and field serviceability.
• Broad Ripple-Frequency Support: Specified ripple current values at both 120 Hz and 100 kHz support performance across low- and high-frequency ripple conditions.
• Long Endurance at Elevated Temperature: 5000 hours at 85°C rating offers a predictable lifetime metric for thermal-stressed installations.
• Wide Operating Temperature: −40°C to +85°C operation allows deployment across a range of industrial ambient conditions.
• Regulatory Compatibility & Availability: RoHS compliance and mass-production status support regulatory needs and volume sourcing.
