Key Features

• Capacitance and Voltage — 12,000 µF nominal capacitance at a 400 V rated voltage, tolerance ±20% (120Hz, 20°C) for bulk energy storage and DC link applications.
• High Ripple Current — 28.5 A at 120 Hz (low frequency) and 39.9 A at 10 kHz (high frequency) to support heavy AC ripple and switching-power applications.
• Endurance and Temperature — Rated for 5000 hours at 85°C with an operating temperature range of −25°C to 85°C, enabling sustained operation under elevated thermal stress.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.2 (20°C, 120 Hz), useful for evaluating dissipation in AC conditions.
• Leakage and Insulation — Leakage current specified up to 5000 µA; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket as specified in the series datasheet.
• Robust Mechanical Package — φ90 × 155 mm can with screw terminals and radial/package case for secure electrical connections and straightforward mounting; supplied in cardboard packing for mass production handling.
• RoHS Compliant — Conforms to RoHS directive requirements for environmental compliance.

Typical Applications

• Power Supply Filtering — Bulk capacitance for smoothing and filtering in DC power supplies where high ripple current capability is required.
• DC Link and Energy Storage — Energy buffering and stabilization in converter or inverter DC-link stages that operate near the 400 V range.
• Industrial Power Equipment — General-purpose use in industrial power electronics that demand extended endurance and robust terminal connections.

Unique Advantages

• Substantial Energy Capacity — 12,000 µF at 400 V provides significant stored energy per component, reducing the number of capacitors required for a given design.
• High Ripple Handling — Specified ripple currents of 28.5 A (120 Hz) and 39.9 A (10 kHz) allow reliable operation with both low- and high-frequency ripple sources.
• Designed for Long Life — 5000 hours rated life at 85°C supports designs that require predictable long-term behavior under continuous ripple loading.
• Secure Screw-Terminal Interface — Screw terminal package simplifies high-current connections and mechanical retention in rugged assemblies.
• Clear Electrical Limits — Specified tan δ (0.2) and leakage/current limits give engineers concrete parameters for thermal and loss budgeting.
• Regulatory Compliance — RoHS-compliant construction supports environmental and regulatory requirements for many end products.
