• Large Capacitance — 3.9 mF (3900 µF) nominal capacitance with ±20% tolerance for bulk energy storage and filtering.
• Screw-Terminal Mounting — Radial can with screw terminals and M5 nominal bolt for reliable, low-resistance connections in high-current circuits.
• High Ripple Current Capability — Rated ripple currents of 14.1 A at 120 Hz and 19.74 A at 100 kHz to support heavy AC ripple and switching power supply loads.
• Elevated Temperature Endurance — Operating range −25°C to +105°C with a rated lifetime of 2000 hours at 105°C under rated ripple conditions.
• Polarized, General-Purpose Design — Polar capacitor intended for conventional DC filtering and energy-storage use in power circuits.
• Physical Dimensions — Body diameter φ76.2 mm and length 150 mm (overall size L: 15 × D: 7.62 cm) for board or chassis mounting using brackets.
• RoHS Compliant — Meets RoHS requirements as indicated in product documentation.

Typical Applications

• Industrial power supplies — Bulk smoothing and DC bus filtering where a 500 V rating and high ripple capability are required.
• Power conversion modules — Energy storage and decoupling in converter stages that demand elevated voltage and sustained ripple handling.
• UPS and backup power systems — Bulk capacitance for energy hold-up in systems operating at high DC voltages and elevated temperatures.
