LNR1J474MSE

The LNR1J474MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNR series, rated at 470000 µF (470 mF) and 63 V. It is a radial can with screw terminals designed for general-purpose power applications that require large capacitance and high ripple handling in a robust, serviceable package.

Engineered for continuous operation from −40°C to +85°C, this capacitor combines high stored energy, significant ripple-current capability, and proven endurance characteristics for demanding industrial and power-electronic environments.

Key Features

• High Capacitance — 470000 µF (470 mF) provides substantial bulk energy storage for smoothing, hold-up and DC-link needs.
• 63 V Rated Voltage — Designed for mid-voltage DC systems where elevated voltage capability is required.
• Screw Terminal Mounting — Robust radial can with screw terminals simplifies high-current connections and mechanical fastening for reliable installation.
• Operating Temperature and Lifetime — Specified for −40°C to +85°C and an endurance rating of 5000 hours at 85°C under rated conditions.
• High Ripple Current Capability — 33.6 A at 120 Hz and 38.64 A at 100 kHz, supporting applications with substantial AC ripple on DC bus lines.
• Leakage and Loss Characteristics — Initial leakage current specified at 5000 µA and tangent of loss angle (tan δ) of 0.6, enabling predictable performance in power systems.
• Reliability Data from Series Datasheet — After endurance testing (D.C. bias plus rated ripple current for 5000 hours at 85°C), capacitance change remains within ±15% and leakage current remains at or below the initial specified value.
• Mechanical Details — φ100 body dimensions (φ100 × 250L / L:25 × D:10 cm) with M8 nominal bolt diameter for the screw terminals on the φ100 size.
• RoHS Compliant & Production Ready — RoHS status compliant and supplied in cardboard packing for mass production handling.

Typical Applications

• Power Supply Bulk Storage — Large capacitance and high ripple-current ratings make it suitable for bulk energy storage and smoothing on DC power rails.
• DC-Link and Inverter Support — Designed to handle the DC bias and ripple currents typical of inverter and power-conversion modules.
• Industrial Power Electronics — Useful in industrial controllers, UPS modules, and other equipment requiring robust, high-capacitance filtering at elevated temperatures.

Unique Advantages

• Substantial Energy Reservoir: 470000 µF provides significant charge storage to stabilize DC rails and extend hold-up time under load.
• High Ripple Handling: Rated ripple currents of 33.6 A (120 Hz) and 38.64 A (100 kHz) reduce thermal stress and support heavy AC components on DC lines.
• Proven Endurance at 85°C: 5000-hour life rating with defined limits (capacitance within ±15% after endurance) supports predictable long-term performance.
• Serviceable Screw-Terminal Design: Screw terminals with M8 nominal bolt on the φ100 body provide secure high-current connections and easier maintenance or replacement.
• Clear Loss and Leakage Specs: Specified tan δ (0.6) and initial leakage current (5000 µA) enable straightforward thermal and loss budgeting in designs.
• Production-Ready Packaging: Cardboard packing and mass-production availability simplify procurement and assembly planning.
