LNR1K473MSE

The LNR1K473MSE from Nichicon is a screw-terminal, polarized aluminum electrolytic capacitor rated for 80 V with 47,000 µF (47 mF) capacitance. It is part of the LNR series of screw terminal capacitors and is offered for general-purpose power applications.

Engineered for robust electrical and mechanical connections, this radial can with screw terminals provides high bulk capacitance, measurable ripple-current handling, and a corrosion- and environment-conscious RoHS-compliant construction. It is supplied in cardboard packing and is in mass production.

Key Features

• High Capacitance: 47,000 µF (47 mF) for substantial bulk energy storage and smoothing in power systems.
• Rated Voltage: 80 V DC rating to support medium-voltage power rails.
• Screw Terminal Mounting: Radial can with screw terminals and M5 bolt nominal terminal for secure, low-impedance connections.
• Electrical Performance: Specified tan δ of 0.25 and leakage current listed at 5,000 µA (5 mA).
• Ripple Current Capability: 12.7 A at 120 Hz and 14.61 A at 100 kHz to support AC ripple on DC rails.
• Operating Temperature & Lifetime: Rated from –40 °C to +85 °C with endurance of 5,000 hours at 85 °C.
• Tolerance & Polarization: Capacitance tolerance ±20% and polarized construction.
• Form Factor: Body diameter φ63.5 mm × length 100 mm (L: 10.0 cm × D: 6.35 cm) for robust chassis mounting; Height seated max 3.937 inches.
• Compliance & Packaging: RoHS-compliant and shipped in cardboard packing; available in mass production volumes.

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing for systems that require high capacitance and a screw-terminal connection style.
• Power supply modules: Supporting DC bus filtering where sustained ripple current capability and 80 V rating are required.
• Industrial equipment: Installed where robust mechanical terminal connections and extended endurance at 85 °C are needed.

Unique Advantages

• Large bulk capacitance: 47,000 µF delivers substantial charge-storage capacity for energy buffering and smoothing.
• Robust screw-terminal interface: Screw-terminal (M5 nominal) mounting ensures secure, low-resistance connections for heavy-current applications.
• Measurable ripple handling: Rated ripple currents (12.7 A at 120 Hz; 14.61 A at 100 kHz) align electrical performance with demanding power rails.
• Extended endurance at elevated temperature: 5,000 hours life rating at 85 °C supports long-term operation in warm operating environments.
• Wide ambient range: –40 °C to +85 °C operating window accommodates varied installation environments.
• Regulatory compliance and production readiness: RoHS-compliant construction and mass-production availability simplify procurement and integration.
