Key Features

• High Voltage & Capacitance — Rated at 450 V with 1.2 mF (1200 µF) capacitance and ±20% tolerance (120 Hz, 20°C), providing substantial energy storage in a single component.
• Screw-Terminal Package — Radial can with screw terminals (M5 nominal bolt size for φ51) for secure, low-impedance connections in high-current installations.
• Endurance at Elevated Temperature — Load life of 2000 hours at 85°C when subjected to rated ripple current, supporting stable performance under sustained thermal stress.
• Ripple Current Performance — Rated ripple current of 6 A at 120 Hz and 8.4 A at 10 kHz, enabling use where significant AC ripple is present on DC rails.
• Leakage Current — Specified leakage current of 2200 µA to assist in system-level leakage budgeting and design validation.
• Operating Temperature Range & Compliance — Operates from –40°C to +85°C and is RoHS compliant (2011/65/EU, (EU)2015/863).
• Compact Mechanical Footprint — Physical size φ51 × 75 mm length (L: 7.5 × D: 5.1 cm) for designs targeting reduced equipment volume; supplied in cardboard packing for mass production handling.

Typical Applications

• General-Purpose Power Electronics — Suited for general-purpose power equipment requiring a 450 V, 1200 µF screw-terminal capacitor.
• Downsized Equipment Designs — Designed for equipment down sizing where high-voltage capacitance in a compact screw-terminal package is needed.
• Industrial Power Systems — Applicable to industrial systems that require a robust screw-terminal capacitor with specified ripple and endurance characteristics.

Unique Advantages

• High Voltage Capability: 450 V rating enables integration into higher-voltage DC systems without stacking multiple lower-voltage parts.
