LNR1E684MSEN

The LNR1E684MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNR series. It delivers very high capacitance in a radial can with screw terminals, designed for general-purpose applications that require substantial bulk capacitance and strong ripple-current capability.

Key value comes from its large 680000 µF capacitance at 25 V, high allowable ripple currents, and an endurance rating qualified for long-term operation at elevated temperature (5000 hours at 85°C).

Key Features

• High Capacitance: 680000 µF (680 mF) nominal capacitance with tolerance ±20% at 120 Hz, 20°C, providing substantial bulk energy storage.
• Rated Voltage: 25 V DC rated voltage for medium-voltage DC systems and power rails.
• Screw-Terminal, Radial Can Package: Robust radial can with screw terminals (φ90 × 220 mm body / L: 22 × D: 9 cm) for secure, high-current connections in assemblies.
• High Ripple Current Capability: Low-frequency ripple current up to 33.3 A (120 Hz) and high-frequency ripple current up to 38.3 A (100 kHz), suitable for demanding ripple environments.
• Loss and Leakage: Specified tan δ (DF) of 1.00 measured at 20°C, 120 Hz; leakage current specified at 5000 µA (5 mA).
• Operating and Endurance Ratings: Operating temperature range –40°C to +85°C with endurance rating of 5000 hours at 85°C (capacitance change within ±15% after endurance test; tan δ and leakage meet specified limits).
• Regulatory and Production: RoHS compliant and available in mass-production quantities; packaged in cardboard packing for shipment.

Typical Applications

• High-capacitance bulk storage — Where 680000 µF of bulk capacitance is needed for energy buffering in power systems or DC bus stabilization.
• Screw-terminal power assemblies — For equipment and modules that require secure screw-terminal connections and a radial can package (φ90 × 220 mm).
• High-ripple circuits — For circuits that must tolerate substantial low-frequency (33.3 A @ 120 Hz) and high-frequency (38.3 A @ 100 kHz) ripple currents.
• General-purpose industrial electronics — Suitable for general-purpose applications within the specified –40°C to +85°C temperature range and 5000-hour endurance at 85°C.

Unique Advantages

• Massive capacitance in a single component: 680000 µF provides significant bulk storage, reducing the need for parallel capacitors and simplifying layout.
• High ripple-handling capability: Rated ripple currents of 33.3 A (120 Hz) and 38.3 A (100 kHz) enable reliable operation in high-current power environments.
• Durability at elevated temperature: 5000-hour endurance at 85°C with defined limits for capacitance change, tan δ, and leakage current supports long-term reliability.
• Secure electrical and mechanical connection: Screw-terminal radial can package provides robust mounting and high-current terminations for assemblies.
• Clear performance specifications: Measured tan δ and leakage values, plus defined temperature range (–40°C to +85°C), allow predictable integration into system designs.
• RoHS compliant and production-ready: Compliant with RoHS and available in mass-production packaging for volume deployments.
