• Screw Terminal Package  Radial can with screw terminals for robust, serviceable connections and simplified wiring in panel- or chassis-mounted applications.
• High Ripple Current Performance  Rated ripple current of 15.10 A at 120 Hz (low frequency) and 21.14 A at 10 kHz (high frequency) to support demanding AC ripple and switching environments.
• Thermal & Lifetime Specification  Operating temperature range −25°C to +85°C with a specified endurance of 5000 hours at 85°C under rated ripple conditions.
• Electrical Losses & Leakage  Dissipation factor (tanδ) 0.2 and leakage current specified at 4360 µA, enabling predictable performance and design margining.
• Form Factor & Dimensions  Large-diameter, screw-terminal can with dimensions φ76.2 × 115 mm (L: 11.5 cm × D: 7.62 cm) for high-capacitance, high-voltage installations.
• Compliance & Packaging  RoHS-compliant construction and supplied in cardboard packing; product is listed as mass production.

Typical Applications

• High-voltage power supplies  Bulk energy storage and smoothing on 450 V rails where 4700 µF capacitance and high ripple-current capability are required.
• DC link and inverter circuits  DC link smoothing and transient support in power conversion stages that demand sustained ripple handling and long endurance at elevated temperatures.
• Industrial power electronics  Bulk filtering and energy buffering in industrial drives and converters using screw-terminal mounting for secure field connections.

Unique Advantages

• High-voltage bulk capacitance: 4700 µF at 450 V provides substantial stored energy per component, reducing the number of parallel devices required for a given capacitance target.
• Robust screw-terminal connections: Screw terminals simplify installation and maintenance while delivering reliable mechanical and electrical contact in chassis-mounted applications.
• Designed for sustained ripple: Specified ripple currents of 15.10 A (120 Hz) and 21.14 A (10 kHz) support both mains-frequency filtering and high-frequency switching environments.
• Long endurance at rated conditions: 5000 hours load life at 85°C with rated ripple ensures predictable aging and performance over extended service intervals.
• Predictable loss and leakage: tanδ = 0.2 and a defined leakage current of 4360 µA allow accurate thermal and leakage budgeting in power designs.
• Regulatory compliance: RoHS status documented for easier integration into compliant end-products.
