Key Features

• Electrical performance — 820 µF nominal capacitance with ±20% tolerance and a rated voltage of 450 V for high-voltage DC applications.
• Ripple current capability — Low-frequency ripple current 4.90 A (120 Hz) and high-frequency ripple current 6.86 A (10 kHz) to handle real-world switching and line-frequency stress.
• Leakage and dissipation — Specified leakage current of 1,820 µA and tanδ of 0.25 (measured conditions provided), enabling predictable loss and self-heating behavior in designs.
• Thermal and lifetime rating — Rated for operation from -40°C to +85°C with a load life (endurance) of 2000 hours at 85°C under rated ripple conditions.
• Mounting and package — Screw terminal, radial can package (φ51 × 60L) with M5 terminal hardware dimensions, simplifying secure, low-impedance connections in power assemblies.
• Regulatory status — RoHS compliant, supplied in cardboard packing and available in mass-production quantities.

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing for high-voltage DC rails where 450 V rating and 820 µF capacitance are required.
• Power conversion and inverters — DC-link and smoothing capacitor for converters and inverter stages that demand reliable ripple handling and screw-terminal connections.
• Energy storage in power electronics — Decoupling and charge reservoir roles in systems that benefit from high capacitance and robust terminal mounting.

Unique Advantages

• High-voltage, high-capacitance combination — 450 V rating paired with 820 µF provides significant stored energy in a compact screw-terminal can.
• Defined ripple-handling specs — Published ripple current values at 120 Hz and 10 kHz allow designers to size cooling and thermal margin precisely.
• Engineered for endurance — 2000-hour load life at 85°C supports long-term operation under rated ripple and voltage stress.
• Screw-terminal reliability — M5 screw terminals enable secure, low-resistance connections suitable for high-current DC applications.
• Wide operating range — -40°C to +85°C rating covers a broad set of industrial ambient conditions.
• Regulatory compliance and production readiness — RoHS compliance and mass-production availability simplify procurement and integration.
