LNR1E474MSEB

The LNR1E474MSEB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications requiring very large capacitance. It combines a 470,000 µF rated capacitance at 25 V with high allowable ripple currents and a polarized screw-terminal package for secure electrical and mechanical connections.

Engineered for sustained operation in demanding environments, the capacitor offers a specified endurance of 5,000 hours at 85°C, a wide operating temperature range from −40°C to 85°C, and RoHS compliance for environmental compatibility.

Key Features

• High Capacitance: 470,000 µF (470 mF) nominal capacitance ideal for large bulk energy storage and DC link applications where substantial charge reservoir is required.
• Rated Voltage & Tolerance: 25 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20°C for predictable performance in design margins.
• High Ripple Current Capability: 30.8 A at 120 Hz (low frequency) and 35.42 A at 100 kHz (high frequency) to handle significant AC ripple on DC buses.
• Electrical Loss and Leakage: Specified tanδ (DF) of 1.00 and a leakage current rating of 5000 µA, enabling designers to assess dissipation and standby leakage for thermal and power budgets.
• Robust Endurance and Temperature Range: Rated for 5,000 hours at 85°C and an operating temperature span of −40°C to 85°C to support long-term stability under elevated-temperature load.
• Screw Terminal Mounting: Radial can with screw terminals provides secure, low-impedance connections suitable for high-current bus installations; package dimensions φ90 × 170 mm (L: 17 × D: 9 cm) facilitate mechanical integration.
• Packaging & Production Status: Supplied in cardboard packing and available in mass production quantities.

Typical Applications

• Power supply bulk filtering: Large capacitance and high ripple-current ratings make the LNR1E474MSEB appropriate for bulk energy storage and smoothing on DC power rails.
• DC bus and inverter support: The screw-terminal package and high ripple tolerance suit use where stable DC link capacitance is required for converters and inverters.
• Industrial power systems: Designed for continuous operation at elevated temperatures (up to 85°C) and long endurance, supporting heavy-duty industrial power electronics and control equipment.

Unique Advantages

• Substantial energy reservoir: 470,000 µF nominal capacitance reduces the number of parallel devices required for large-capacitance designs, simplifying BOM and layout.
• High ripple handling: 30.8 A (120 Hz) and 35.42 A (100 kHz) ripple current ratings help minimize overheating and voltage ripple under continuous load.
• Durability at elevated temperature: 5,000-hour rated endurance at 85°C provides predictable aging characteristics for long-term system reliability planning.
• Secure, low-impedance connections: Screw terminals and a radial can form factor deliver robust mechanical fastening and reliable current paths for high-current applications.
• Design transparency: Clear specifications for tanδ, leakage current, tolerance, and temperature range allow straightforward thermal and electrical margin calculations.
• Regulatory compliance: RoHS compliance supports use in environments requiring restricted-substance conformity.
