LNR1H474MSE

The LNR1H474MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNR series, offering 470000µF (470 mF) of capacitance at a 50 V rating. Engineered for general-purpose power applications, it delivers high bulk capacitance, substantial ripple current handling, and robust endurance for demanding electronic systems.

Key Features

• High Capacitance & Voltage: 470000µF nominal capacitance at 50 V provides large energy storage in a single radial can package (φ90 × 220 mm / L: 22 cm × D: 9 cm).
• Screw Terminal Mounting: Radial can with screw terminals simplifies high-current connections; nominal terminal bolt for φ90 size is M5 and capacitors φ51 or larger are furnished with a 3-leg mounting bracket as standard.
• High Ripple Current Capability: Rated for 33.2 A at 120 Hz (low frequency) and 38.18 A at 100 kHz (high frequency), supporting heavy AC ripple conditions tied to power conversion and filtering tasks.
• Endurance & Temperature Range: 5000 hours life rating at 85°C with an operating temperature range of −40°C to +85°C, supporting extended service in elevated-temperature environments.
• Electrical Performance: Specified tangent of loss angle (tan δ) of 0.75 at 20°C and 120 Hz and a leakage current of 5000µA, enabling predictable AC loss and leakage characteristics.
• Compliance & Packaging: RoHS compliant and supplied in cardboard packing; status: mass production.

Typical Applications

• General-Purpose Power Systems – Designs requiring large bulk capacitance at 50 V with high ripple current handling and screw-terminal connections.
• Industrial Electronics – Power modules and assemblies where long endurance (5000 hours at 85°C) and robust mounting are required.
• Energy Storage and Filtering – Circuits that need substantial stored charge and AC ripple smoothing within the specified temperature and leakage limits.

Unique Advantages

• Single-Component Bulk Capacitance: 470000µF provides substantial energy storage in one radial can, simplifying board layout and reducing the number of parallel capacitors needed.
• High Ripple Tolerance: Rated ripple currents of 33.2 A and 38.18 A directly address demanding AC ripple conditions in power conversion and filtering applications.
• Secure, High-Current Termination: Screw terminals and M5 nominal bolt diameter for φ90 size enable reliable mechanical and electrical connections for heavy-current paths.
• Proven Endurance: 5000-hour life at 85°C with defined capacitance and tan δ limits after endurance testing supports predictable long-term performance.
• Regulatory Compliance: RoHS compliance aligns the component with common environmental requirements for electronic assemblies.
• Production Availability: Listed as mass production, indicating established manufacturing supply for production-volume needs.
