LNR2D473MSEN

The LNR2D473MSEN is a Nichicon LNR series aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It delivers 47 mF of capacitance at a 200 V rating, housed in a φ90 × 220 mm can, and is supplied in cardboard packing for mass production.

Engineered for high-capacitance bulk energy handling, the LNR2D473MSEN combines high ripple-current capability, long endurance at elevated temperature, and RoHS compliance for reliable performance in industrial and power-electronics systems.

Key Features

• High Capacitance — 47 mF (47,000 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C, suitable where large bulk capacitance is required.
• High Voltage Rating — Rated at 200 V, enabling use in higher-voltage DC link and power-supply applications.
• Screw Terminal Package — Radial can with screw terminals designed for secure bolted connections (φ90 size utilizes M5 nominal bolt), supplied with standard 3-leg mounting bracket for φ51 and larger bodies.
• Robust Ripple Handling — Rated ripple current of 20.9 A at 120 Hz and 25.08 A at 100 kHz, supporting demanding AC ripple conditions.
• Endurance and Reliability — 5,000 hours endurance at 85°C under DC bias plus rated ripple current; after endurance test, capacitance change remains within ±15% and leakage current meets initial specification.
• Low-Frequency and High-Frequency Performance — Specified ripple limits at both 120 Hz and 100 kHz to address a range of power-conversion scenarios.
• Leakage and Loss Characteristics — Specified leakage current up to 5,000 µA and tan δ of 0.25, providing predictable loss and self-discharge behavior for system design.
• Temperature Range and Compliance — Operating temperature range of −25°C to +85°C for the 160–250 V class; RoHS compliant.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage in higher-voltage power-supply rails where 47 mF at 200 V is required.
• DC link and inverter systems — High-voltage DC link support with rated ripple current specifications for switching-frequency ripple management.
• Industrial power electronics — Energy buffering and filtering in industrial converters and power-conditioning equipment operating within −25°C to +85°C.

Unique Advantages

• Large energy storage in a screw-terminal can: 47 mF at 200 V provides substantial bulk capacitance for high-voltage systems while enabling secure M5-bolt terminal connections.
• Designed for ripple-heavy environments: Separate ripple current ratings at 120 Hz and 100 kHz let engineers size the capacitor for both low-frequency and switching-frequency stress.
• Proven endurance at elevated temperature: 5,000 h at 85°C with defined limits on capacitance change and tan δ, supporting predictable lifetime performance.
• Measurable electrical characteristics: Specified leakage current (5,000 µA) and tan δ (0.25) allow accurate thermal and loss budgeting in system designs.
• Mechanical mounting convenience: Standard 3-leg bracket for φ90 bodies simplifies fixture and chassis installation for larger can sizes.
• RoHS compliant: Meets environmental compliance requirements for a wide range of commercial and industrial deployments.
