LNR2D473MSEB

The LNR2D473MSEB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power-electronics use. It provides 47,000 µF capacitance at a 200 V rating with screw terminals for reliable, low-impedance power connections.

Engineered for applications that require high bulk capacitance and sustained ripple handling, this part combines high ripple-current capability, long endurance at elevated temperature, and a large-format mechanical package (φ90 × 220L) supplied in cardboard packing. Status: Mass Production.

Key Features

• Capacitance & Voltage — 47,000 µF (47 mF) rated at 200 V with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Screw-Terminal Construction — Radial can with screw terminals for robust, low-resistance power connections and simplified mounting.
• High Ripple-Current Capability — Low-frequency ripple current 20.9 A (120 Hz) and high-frequency ripple current 25.08 A (100 kHz) to support heavy AC ripple environments.
• Loss and Leakage — Tangent of loss angle (tanδ) = 0.25 (measured at 20°C, 120 Hz) and leakage current specified at 5,000 µA.
• Thermal Range & Endurance — Operating temperature −25°C to +85°C and rated endurance of 5,000 hours at 85°C under DC bias plus rated ripple current.
• Mechanical Size & Packaging — Large-format body φ90 × 220L (L: 220 mm × D: 90 mm) supplied in cardboard packing; suitable for systems that require high-capacitance modules.
• RoHS Compliant — Meets RoHS requirements for environmental compliance.

Typical Applications

• Power supplies and DC-link smoothing — Bulk energy storage and ripple smoothing where 47,000 µF at 200 V is required for hold-up and filtering.
• Industrial inverters and motor drives — High ripple-current capability and screw-terminal connections support robust DC-link and filtering in inverter stages.
• UPS and energy-storage modules — Large capacitance and endurance at 85°C provide stable filtering and energy buffering for backup and storage systems.

Unique Advantages

• Large-capacitance solution: 47,000 µF at 200 V reduces the number of parallel capacitors required for high-energy designs, simplifying layout and BOM.
• High ripple handling: Specified ripple currents of 20.9 A (120 Hz) and 25.08 A (100 kHz) enable use in designs with significant AC ripple or switching noise.
• Robust screw-terminal mounting: Screw terminals and a radial can simplify high-current connections and improve mechanical stability in demanding assemblies.
• Designed for elevated-temperature endurance: 5,000 hours specified at 85°C under rated conditions supports reliable operation in thermally stressed enclosures.
• Measurable loss and leakage characteristics: tanδ = 0.25 (20°C, 120 Hz) and leakage current of 5,000 µA provide clear electrical baselines for design margining and thermal planning.
