Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) nominal capacitance with a rated voltage of 450 V; capacitance tolerance ±20% at 120 Hz, 20°C.
• High Ripple Capability — Rated ripple current of 9.7 A at 120 Hz and 13.58 A at 100 kHz to support heavy ripple-loading applications.
• Long Endurance at Elevated Temperature — Designed for 20,000 hours of operation at +85°C when subjected to the rated ripple current; endurance verified after restoration to 20°C.
• Temperature Stability — Operating range from −25°C to +85°C with an impedance ratio Z(−25°C)/Z(+20°C) up to 8 for low-temperature performance.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C).
• Mounting & Package — Radial can with screw terminals for secure, low-resistance connections; physical size L: 11 cm × D: 7.62 cm and maximum seated height 4.331 inches.
• Reliability & Marking — Marked with white print on a black sleeve; shelf-life and endurance procedures specified (shelf life test: 1000 hours at 85°C followed by voltage treatment).
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU,(EU)2015/863); flame-retardant electrolyte available by type.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in high-voltage industrial supplies where sustained ripple current and long life are required.
• Inverter Circuitry — DC-link and filtering duties in inverter systems that demand extra-high voltage and high ripple handling capability.
• High-Ripple Filtering — Applications requiring robust ripple dissipation at both low and high frequencies, leveraging specified ripple current ratings at 120 Hz and 100 kHz.
• Extra-High Voltage Applications — Systems needing capacitors rated for 450 V where reliability under continuous load and elevated temperature is essential.

Unique Advantages

• High ripple endurance: Specified ripple currents (9.7 A at 120 Hz, 13.58 A at 100 kHz) combined with a 20,000-hour rated life at +85°C reduce the need for frequent replacements in high-stress applications.
• Extra-high voltage rating: 450 V rating enables use in higher-voltage DC-link and power conversion designs without additional series stacking.
• Robust screw-terminal construction: Screw terminals provide secure, serviceable connections for heavy-current installations and simplify maintenance.
• Validated low-temperature performance: Impedance control down to −25°C (Z ratio ≤ 8) supports reliable operation across broad ambient ranges.
• Clear leakage and endurance specifications: Leakage current limits and defined endurance and shelf-life tests support predictable design margins and qualification steps.
• Compliance and safety options: RoHS compliance and availability of flame-retardant electrolyte types support regulatory and safety-conscious designs.
