LNR1A684MSE

The LNR1A684MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNR series, offering very high capacitance in a radial can with screw terminals. Designed for general-purpose power applications, it provides bulk energy storage with robust ripple-handling and low equivalent series resistance.

Key electrical characteristics include 680000 µF capacitance at 10 V, an ESR of 1.6 mΩ (measured at 120 Hz), rated ripple-current capability up to 22.8 A at 120 Hz and 26.22 A at 100 kHz, and a 5000-hour rated lifetime at 85°C. The unit is RoHS compliant.

Key Features

• High Capacitance — 680000 µF (680 mF) provides substantial bulk energy storage for hold-up, smoothing, and transient support in power systems.
• Rated Voltage & Tolerance — 10 V nominal rating with ±20% capacitance tolerance for predictable performance in specified voltage environments.
• Low ESR and High Ripple Handling — 1.6 mΩ ESR at 120 Hz combined with 22.8 A (120 Hz) and 26.22 A (100 kHz) ripple-current ratings supports efficient ripple dissipation and thermal performance under AC stress.
• Screw-Terminal Mounting — Radial can with screw terminals (φ76.2 × 120 mm body) and M5-compatible terminal hardware for secure, low-resistance connections in power assemblies.
• Operational Robustness — Rated operating temperature range from −40°C to +85°C and a specified endurance of 5000 hours at 85°C under DC bias plus rated ripple current.
• Leakage and Reliability — Leakage current specified up to 5000 µA and endurance limits defined by Nichicon’s LNR series tests for capacitance, tan δ, and leakage after life and shelf-life conditions.
• Regulatory Compliance — RoHS compliant construction for use in lead-restricted assemblies.

Typical Applications

• General Purpose Power Systems — Bulk energy storage and smoothing in power supply designs where large capacitance and high ripple capability are needed.
• Industrial Power Modules — DC bus and filtering applications benefiting from low ESR and high ripple-current handling in screw-terminal installations.
• Backup and Hold-Up Circuits — Energy-hold applications that require substantial stored charge and predictable leakage and lifetime characteristics.

Unique Advantages

• Exceptional Bulk Storage: 680000 µF capacitance delivers extended energy reserve for hold-up and smoothing tasks, reducing the need for multiple smaller capacitors.
• Efficient Thermal and Ripple Performance: 1.6 mΩ ESR with high ripple-current ratings (22.8 A at 120 Hz, 26.22 A at 100 kHz) minimizes heating and improves lifetime under AC stress.
• Robust Mechanical Termination: Screw-terminal radial can design and M5-compatible terminals provide secure, low-resistance connections suitable for repeatable assembly and serviceability.
• Designed for Long Service Life: 5000-hour endurance at 85°C under rated conditions gives predictable aging characteristics for planning maintenance and lifecycle costs.
• Wide Temperature Range: −40°C to +85°C operating range supports deployment across a broad range of environmental conditions.
