LNR2A473MSE

The LNR2A473MSE from Nichicon is a screw‑terminal, polarized aluminum electrolytic capacitor rated at 100 V with a nominal capacitance of 47,000 µF (47 mF). It is part of the LNR series of radial, can‑style screw terminal capacitors designed for general‑purpose applications that require high capacitance, robust terminal mounting, and extended operational life.

This unit delivers high ripple handling and long endurance at elevated temperature, making it suitable for systems that need bulk energy storage and reliable DC bias performance within a −40°C to 85°C operating window.

Key Features

• Capacitance & Voltage — 47,000 µF nominal capacitance at a rated voltage of 100 V, with ±20% tolerance.
• High Ripple Capability — Low‑frequency ripple current of 14.4 A (120 Hz) and high‑frequency ripple current of 16.56 A (100 kHz) to support demanding ripple environments.
• Endurance and Reliability — Rated for 5,000 hours at 85°C under D.C. bias plus rated ripple current; after the endurance test capacitance change remains within ±15%, tan δ within 175% of initial, and leakage current remains at or below the initial specified value.
• Leakage and Loss — Initial leakage current specified at 5,000 µA and tan δ up to 0.2 (measurement reference provided in product data).
• Mechanical Package & Mounting — Radial can with screw terminals (φ63.5 × 140 mm body/length), supplied with screw‑terminal mounting for secure electrical and mechanical connections.
• Operating Range & Compliance — Rated for −40°C to 85°C operation and RoHS compliant; supplied in cardboard packing and available in mass production.

Typical Applications

• General Purpose — Designed for general‑purpose systems requiring a high‑capacitance, 100 V screw‑terminal electrolytic capacitor.
• High‑Ripple Power Circuits — Suited to circuits where significant ripple currents are present, supported by 14.4 A (120 Hz) and 16.56 A (100 kHz) ripple current ratings.
• Wide Ambient Environments — Applicable where operation across −40°C to 85°C is required and long term endurance (5,000 h at 85°C) is important.

Unique Advantages

• Large Stored Energy: 47,000 µF at 100 V provides substantial bulk capacitance for reservoir and smoothing roles in high‑voltage systems.
• Robust Terminal Mounting: Screw‑terminal construction ensures secure electrical connection and mechanical stability for panel or chassis installations.
• High Ripple Handling: Specified ripple currents at both low and high frequency support designs with significant AC components or switching‑noise environments.
• Proven Endurance: 5,000 hours rated life at 85°C with defined post‑test limits on capacitance, tan δ, and leakage for predictable long‑term performance.
• Compliance and Availability: RoHS compliant and shipped in cardboard packing; the part is in mass production for supply consistency.
