LNR1E474MSE

The LNR1E474MSE is a screw‑terminal, polarized aluminum electrolytic capacitor from Nichicon’s LNR series. It provides 470000 µF (470 mF) capacitance at a 25 V rating in a radial can with screw terminals for secure electrical and mechanical connection.

Designed for general‑purpose power applications, this capacitor combines very high capacitance with significant ripple current handling and a long 5000‑hour endurance at 85°C, making it suitable for bulk energy storage and power smoothing in industrial and power electronics equipment.

Key Features

• Capacitance & Voltage — 470000 µF (470 mF) nominal capacitance with a 25 V rated voltage and a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Screw‑Terminal, Radial Can Package — Screw terminal mounting for robust, low‑impedance connections; package described as radial, can with screw terminals and supplied in cardboard packing.
• High Ripple Current Capability — Low‑frequency ripple current of 30.8 A at 120 Hz and high‑frequency ripple current of 35.42 A at 100 kHz, specified for the part to support demanding AC ripple conditions.
• Endurance and Reliability — Rated for 5000 hours at 85°C under DC bias plus rated ripple current; after endurance testing, capacitance change is within ±15%, tanδ remains within 175% of initial, and leakage current stays at or below the initial specified value per series endurance criteria.
• Leakage and Dissipation — Specified leakage current of 5000 µA; tangent of loss angle (tanδ) of 1 under measurement conditions of 20°C, 120 Hz.
• Operating Temperature Range — Specified to operate from −40°C to +85°C for this voltage class.
• Physical Dimensions — Large‑format body with size listed as φ90 × 170 L (L: 17 × D: 9 cm), suitable where high capacitance density is required.
• Compliance & Production — RoHS‑compliant and listed as mass production status by the manufacturer.

Typical Applications

• Power supply smoothing — Bulk energy storage and smoothing in DC power supplies where high capacitance reduces voltage ripple under load.
• DC bus and energy buffering — Bulk decoupling and transient energy support for DC bus systems in industrial converters and inverters.
• UPS and backup modules — Large capacitance and defined endurance at 85°C provide retention of stored energy and reliable ripple handling in backup and hold‑up designs.
• Motor drives and power electronics — High low‑ and high‑frequency ripple current capability for use in drives, power conditioners, and similar industrial power circuits.

Unique Advantages

• Very high capacitance in a single component: 470000 µF provides substantial bulk energy storage to reduce part count and simplify power stack design.
• Screw‑terminal connectivity: Provides secure, low‑impedance connections for high current paths and easier assembly in field or industrial installations.
• High ripple current handling: Specified 30.8 A at 120 Hz and 35.42 A at 100 kHz supports both low‑ and high‑frequency ripple environments without need for additional parallel components.
• Long endurance at elevated temperature: 5000 hours at 85°C under rated conditions with defined post‑test limits on capacitance, tanδ and leakage for predictable long‑term behavior.
• Clear electrical characterization: Defined tanδ (1 at 20°C, 120 Hz), leakage current specification, and tolerance make it straightforward to incorporate into engineering calculations and reliability assessments.
• RoHS‑compliant and production ready: Meets RoHS requirements and is listed as mass production, facilitating procurement and volume use.
