LNR1V474MSEN

The LNR1V474MSEN from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNR series, offering a very large capacitance of 470,000 µF at a rated voltage of 35 V. Designed for general‑purpose power applications, it combines high bulk energy storage with robust screw‑terminal mounting for secure high‑current connections.

With high ripple‑current capability, extended endurance at elevated temperature, and RoHS compliance, this capacitor targets systems that require reliable bulk smoothing and energy buffering under sustained load.

Key Features

• High Capacitance & Rated Voltage — 470,000 µF nominal capacitance at 35 V with ±20% tolerance (measured at 120 Hz, 20°C), providing substantial bulk energy storage.
• Screw Terminal Mounting (Radial Can) — Screw‑terminal package for secure, low‑impedance terminations; for the φ90 body this corresponds to the M5 nominal bolt size specified for this series.
• High Ripple Current Handling — Rated low‑frequency ripple current of 32.6 A at 120 Hz and high‑frequency ripple current of 37.49 A at 100 kHz, enabling sustained AC stress handling in power circuits.
• Endurance at Elevated Temperature — 5,000 hours life at 85°C under rated DC bias plus ripple current; after endurance test, capacitance change is within ±15% and leakage current remains at or below initial specified value.
• Leakage, Dissipation & Loss — Leakage current specified at 5,000 µA; tangent of loss angle (tan δ) 0.9 measured at 20°C, 120 Hz for design consideration of ESR/DF.
• Operating Temperature Range — Rated for −40°C to +85°C, supporting a wide range of environmental conditions.
• Physical & Packaging Details — Large form factor φ90 × 170 mm (L: 17 × D: 9 cm) radial can with screw terminals; supplied in cardboard packing; product is in mass production and RoHS compliant.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing for power supplies and power conversion stages where large capacitance and high ripple handling are required.
• UPS and backup power — Energy buffering for transient support and hold‑up time in uninterruptible power modules.
• Industrial power electronics — DC link and smoothing applications in converters and inverters that demand high ripple current capability and long endurance at elevated temperature.

Unique Advantages

• Substantial energy capacity: 470,000 µF provides a large reservoir for transient suppression and hold‑up without multiple smaller capacitors.
• Secure high‑current termination: Screw‑terminal radial can construction with M5 nominal bolt size for the φ90 body ensures reliable mechanical and electrical connections under heavy current.
• High ripple tolerance: Explicit low‑ and high‑frequency ripple ratings (32.6 A @120 Hz, 37.49 A @100 kHz) support demanding AC stress in power circuits.
• Proven endurance: 5,000 hours at 85°C with defined post‑test limits on capacitance, tan δ and leakage current gives predictable lifetime behavior under stress.
• Wide operating temperature: −40°C to +85°C covers a broad range of installation environments for industrial and general‑purpose systems.
• Compliance and supply readiness: RoHS compliant and available in mass production with cardboard packing for straightforward procurement and assembly handling.
