LNR1E474MSEN

The LNR1E474MSEN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNR series, offering very high capacitance (470000 µF) at a rated voltage of 25 V. It is a radial can with screw terminals designed for general-purpose power applications that require large bulk capacitance, high ripple handling and robust endurance at elevated temperature.

Key value comes from its combination of extremely high capacitance, high ripple-current capability and a 5000‑hour endurance rating at 85°C, making it suitable for systems that need reliable bulk energy storage and smoothing in compact screw-terminal packaging.

Key Features

• Very high capacitance: 470000 µF (470 mF) provides substantial bulk energy storage and smoothing in power systems requiring large capacitance.
• Rated voltage and tolerance: 25 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20°C.
• High ripple current handling: 30.8 A at 120 Hz (low frequency) and 35.42 A at 100 kHz (high frequency) to support heavy ripple and transient loads.
• Low-frequency loss characteristic: tan δ (DF) 1.00, specified for loss-angle performance.
• Leakage control: Leakage current specified at 5000 µA after application of rated voltage.
• Endurance and temperature range: 5000 hours life at 85°C and an operating temperature range of −40°C to +85°C.
• Robust mechanical package: Radial can with screw terminals (φ90 × 170 mm body), supplied in cardboard packing and available in mass production quantities.
• RoHS compliant: Meets RoHS requirements as provided in the product data.

Typical Applications

• Power supply bulk storage: High capacitance and high ripple-current capability make this part suitable for bulk energy storage and smoothing in general-purpose power supplies.
• DC bus and filtering: Screw-terminal radial can packaging and strong ripple handling support DC bus filtering and decoupling in industrial and commercial equipment.
• High-energy reservoir: Large capacitance and long endurance at 85°C provide a reliable reservoir for systems with frequent load transients or high inrush currents.

Unique Advantages

• Exceptional bulk capacitance: 470000 µF provides a high-density solution for applications requiring significant stored charge without parallel arrays of smaller capacitors.
• Screw-terminal convenience: Heavy-current screw terminals simplify mechanical and electrical connections for high-current power assemblies.
• High ripple tolerance: Specified ripple current at both low and high frequencies supports a wide range of converter and filter topologies.
• Long endurance at elevated temperature: 5000 hours at 85°C gives designers a measurable reliability baseline for deployed systems.
• Wide operating temperature: −40°C to +85°C rating allows use across varied environmental conditions within the specified range.
• Production-ready supply: Cardboard-packed, mass-production availability helps simplify procurement and inventory planning.
