Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance rated at 400 V DC with ±20% tolerance (120 Hz, 20°C).
• High Ripple Current Capability — 16.10 A low-frequency ripple current (120 Hz) and 22.54 A high-frequency ripple current (10 kHz) to support heavy AC and switching loads.
• Low Leakage & Dissipation — Leakage current specified at 4110 µA and tangent of loss angle (tan δ) of 0.2 for predictable power loss and thermal behavior.
• Thermal and Endurance Rating — Rated for operation from −40°C to +105°C with a 5000-hour load life/endurance at 105°C under rated ripple conditions.
• Package & Mounting — Radial can with screw terminals (φ63.5 × 120 mm) and M5 nominal bolt interface for secure mechanical and electrical connections.
• Polarized, RoHS Compliant — Polarized electrolytic design suitable for DC link and energy-storage functions and compliant with RoHS requirements.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in high-voltage DC power rails for inverter-fed systems.
• Motor Drive & Servo Inverters — Handles high-frequency regenerative voltages and rapid charge–discharge cycles in AC servomotor and general inverter applications.
• High-Speed Charge–Discharge Circuits — Supports circuits that require robust charge-transfer capability due to its high ripple-current rating and endurance.

Unique Advantages
