LNR1V684MSEB

The LNR1V684MSEB is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications requiring very high capacitance. It is a polarized, radial can-type capacitor with screw terminals and a body dimension listed as φ90×220L, rated at 680000 µF and 35 V.

This unit delivers high bulk capacitance with robust ripple-current capability and long endurance at elevated temperature, making it suitable where large energy storage and reliable performance at up to 85°C are required.

Key Features

• High Capacitance: 680000 µF (680 mF) nominal capacitance for large bulk energy storage and smoothing in power systems.
• Rated Voltage: 35 V working voltage suitable for mid-voltage DC applications that require substantial capacitance.
• Ripple Current Capability: Rated ripple current of 35.2 A at 120 Hz and 40.48 A at 100 kHz to handle significant AC ripple under load.
• Endurance at Elevated Temperature: Specified life of 5000 hours at 85°C with performance limits defined for capacitance change, tan δ, and leakage current after the endurance test.
• Leakage Current and Loss Angle: Leakage current specified at 5000 µA and a tangent of loss angle (tan δ) of 0.9, providing quantified electrical loss characteristics.
• Robust Mechanical Design: Screw terminal, radial can package (φ90 body) with standard 3-leg bracket mounting for body diameters φ51 and larger; nominal bolt size for φ90 indicated as M5 in the series documentation.
• Operating Temperature Range: –40°C to +85°C, supporting a wide ambient range for industrial and general-purpose installations.
• RoHS Compliance: Environmentally compliant construction as noted in product data.

Typical Applications

• General-purpose power systems — Provides large bulk capacitance for smoothing and energy buffering in systems described as "general purpose" in the product data.
• High-capacitance DC bus — Screw-terminal radial can package and high ripple current ratings support use where a substantial DC bus capacitor is required within the specified voltage and temperature limits.
• Industrial equipment — Suitable for general-purpose industrial applications that need long-life capacitors with quantified endurance at 85°C.

Unique Advantages

• Massive bulk capacitance: 680000 µF enables substantial energy storage in a single component, simplifying designs that require high capacitance.
• High ripple-current handling: 35.2 A (120 Hz) and 40.48 A (100 kHz) ratings reduce the need for multiple parallel capacitors under high ripple conditions.
• Long endurance at elevated temperature: 5000 hours at 85°C with defined limits for capacitance, tan δ and leakage current supports predictable lifetime performance.
• Screw-terminal convenience: Robust screw-terminal and radial can package with standard bracket mounting for secure mechanical and electrical connections in bulky assemblies.
• Quantified electrical losses and leakage: Specified tan δ of 0.9 and leakage current of 5000 µA give clear electrical parameters for design verification.
• Regulatory compliance: RoHS-compliant construction addresses environmental requirements.
