• Endurance at Elevated Temperature: Load life of 2000 hours at 85°C when subjected to rated ripple current, enabling reliable operation in warm environments.
• Leakage and Loss Characteristics: Specified leakage current 3970 µA and tangent of loss angle (tan δ) 0.25 measured at 20°C, 120 Hz for predictable electrical behavior.
• Operating Temperature Range: –40°C to +85°C to accommodate a wide range of ambient conditions.
• Safety and Insulation: Series datasheet specifies insulation resistance >100 MΩ at DC 500 V between terminal and bracket and voltage proof AC 2500 V for 1 minute between terminal and bracket.
• Regulatory Compliance: RoHS compliant and supplied in cardboard packing; product is in mass production.

Typical Applications

• Power Supply Bulk & Smoothing: High capacitance and high-voltage rating make this part suitable for bulk energy storage and smoothing in general-purpose power supplies and converters.
• DC Link and Inverter Circuits: 450 V rating and substantial ripple current capability support use in DC link circuits and power conversion stages.
• Industrial Power Electronics: Robust screw terminals and 2000-hour endurance at 85°C address the needs of industrial converters and power control equipment.

Unique Advantages

• High Stored Energy Density: 3.9 mF at 450 V delivers significant bulk capacitance in a single radial can, reducing the need for parallel components.
