• High Ripple Current Handling Low-frequency ripple current of 24.2 A (120 Hz) and high-frequency ripple current of 27.83 A (100 kHz) to support high-load power conditioning.
• Endurance at Elevated Temperature Rated life/endurance of 2,000 hours at +105°C under specified conditions.
• Leakage and Loss Characteristics Specified leakage current of 5,000 µA and tangent of loss angle (tan δ) of 1.5 measured at 20°C, 120 Hz.
• Rugged Screw-Terminal Package Radial can with screw terminals for secure electrical and mechanical connections; package dimensions approximately φ90 × 220 mm (L: 22 × D: 9 cm).
• Wide Operating Range and Compliance Operating temperature range of −40°C to +105°C and RoHS compliance. Packaged in cardboard for handling and shipping; product status: Mass Production.

Typical Applications

• Industrial Power Supplies Bulk energy storage and smoothing where 680,000 µF at 25 V and multi-amp ripple handling are required to stabilize DC rails.
• UPS and Backup Systems Energy reservoir for short-term power support and filtering in systems that demand large capacitance and sustained ripple current capability.
• Motor Drive and Power Conversion DC link and buffer capacitor in converters and motor drives that benefit from high capacitance and robust screw-terminal connections.

Unique Advantages

• Massive Bulk Capacitance: 680,000 µF provides substantial energy storage in a single component, reducing the need for parallel arrays.
• High Ripple Current Capacity: 24.2 A (120 Hz) and 27.83 A (100 kHz) ratings support heavy AC ripple and dynamic load conditions.
• High-Temperature Endurance: 2,000-hour rated life at 105°C helps maintain long-term performance in thermally demanding installations.
• Secure Screw-Terminal Mounting: Screw terminals and a radial can package simplify installation and provide reliable high-current connections.
• Clear Specification Set: Defined leakage current (5,000 µA) and tan δ (1.5 at 20°C, 120 Hz) allow predictable design margins.
• RoHS Compliant and Production-Ready: RoHS status and Mass Production availability support volume deployment and regulatory requirements.
