• Temperature and endurance: Rated operating temperature −25°C to 105°C with a specified life/endurance of 5000 hours at 105°C.
• Electrical characteristics: Capacitance tolerance −20% to +20% and tangent of loss angle (tan δ) 0.2 measured at 20°C, 120 Hz for predictable AC performance.
• Leakage current: Specified leakage current of 3970 µA for planning static loss and hold-up characteristics.
• Mechanical & mounting: Radial can with screw terminals and a φ63.5 × 170 mm (L: 17 cm × D: 6.35 cm) form factor for sturdy, serviceable mounting in power racks and assemblies.
• Packaging & compliance: Supplied in cardboard packing and RoHS compliant; part is in mass production.

Typical Applications

• High-voltage power supplies: Bulk energy storage and smoothing in high-voltage DC supplies, leveraging 450 V rating and 3.9 mF capacitance to improve hold-up and transient response.
• Power conversion and inverters: DC-link and filter capacitor for industrial inverters and converters where high ripple current capability is required.
• Motor drives and industrial controls: Energy buffering and filtering in motor drive power stages to support high-current pulse loads.
• Rectifier and power-conditioning systems: Smoothing at the output of high-voltage rectifiers and power-conditioning equipment using the part’s high-rated voltage and robust leakage and ripple specifications.

Unique Advantages

• High-voltage energy density: 450 V rating combined with 3.9 mF capacitance delivers substantial stored energy in a single radial can, reducing the need for parallel parts.
• Designed for high ripple environments: Significant low- and high-frequency ripple current ratings (18.3 A at 120 Hz, 25.62 A at 100 kHz) help maintain temperature stability under continuous ripple loading.
• Extended thermal endurance: Specified 5000 hours at 105°C provides predictable lifetime planning for sustained high-temperature applications.
• Secure, serviceable connections: Screw terminal mounting enables reliable high-current connections and straightforward field installation or replacement.
• Measurable AC performance: tan δ = 0.2 (20°C, 120 Hz) and defined leakage current enable engineers to quantify loss and hold-up behavior during design.
• Production readiness and compliance: RoHS compliant and listed as mass production, supporting volume procurement and regulatory needs.
