LNR2D472MSEN

The LNR2D472MSEN from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNR series, specified for general-purpose power applications. It provides bulk capacitance of 4700 µF (4.7 mF) at a rated voltage of 200 V in a radial can with screw terminals, optimized for robust electrical connection and serviceability.

Key value propositions include high-voltage bulk energy storage, substantial ripple-current capability at both low and high frequencies, and an endurance rating of 5000 hours at 85°C for reliable operation in sustained-duty environments.

Key Features

• Capacitance & Voltage: 4700 µF (4.7 mF) rated at 200 V for high-voltage bulk energy storage and smoothing in power systems.
• Electrical Performance: Tangent of loss angle (tanδ) 0.15 at 20°C (measured at 120 Hz) and capacitance tolerance ±20% (120 Hz, 20°C) for predictable impedance and loss characteristics.
• Ripple Current Capability: Low-frequency ripple current 6.3 A at 120 Hz and high-frequency ripple current 7.56 A at 100 kHz to support AC ripple filtering across a range of switching and line frequencies.
• Leakage Current: Specified leakage current 2900 µA after rated voltage application, providing a defined self-discharge characteristic for system design.
• Endurance & Reliability: Rated life of 5000 hours at 85°C with post-endurance requirements of capacitance change within ±15%, tanδ ≤175% of initial, and leakage current ≤ initial specified value.
• Package & Mounting: Radial can with screw terminals (φ51 × 100 L, L: 10 cm × D: 5.1 cm). Capacitors φ51 and larger are furnished with a 3-leg bracket as standard for secure mechanical mounting.
• Environmental Compliance & Packaging: RoHS compliant and supplied in cardboard packing; product is in mass production.

Typical Applications

• High-Voltage Power Supplies: Bulk smoothing and energy storage for DC-link and high-voltage supply rails where 200 V rated capacitance is required.
• Power Conversion and Inverters: AC ripple filtering and energy buffering in converters and inverters that demand high capacitance and defined ripple current capability.
• Industrial and General-Purpose Equipment: General-purpose power conditioning in industrial controllers and equipment that benefit from screw-terminal mounting and extended endurance at elevated temperature.

Unique Advantages

• High-Voltage Bulk Storage: 4700 µF at 200 V delivers substantial stored energy for DC-link and smoothing tasks without stacking multiple capacitors.
• Dual-Frequency Ripple Handling: Rated ripple currents specified at both 120 Hz (6.3 A) and 100 kHz (7.56 A) allow designers to size capacitors based on the dominant ripple environment.
• Screw Terminal Connectivity: Robust screw terminals enable secure, low-resistance connections and easy field installation or replacement.
• Long Endurance Specification: 5000 hours at 85°C with defined post-test limits gives a measurable reliability baseline for long-run designs.
• Serviceable Mounting: Standard 3-leg bracket for φ51 bodies simplifies mechanical fixation and vibration resistance for larger can sizes.
• Regulatory Compliance: RoHS compliance supports use in regulated products and simplifies environmental reporting.
