LNU2G682MSEJBN

The LNU2G682MSEJBN is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNU series, rated at 6800 µF and 400 V with an operating temperature range of −40 °C to +105 °C. It combines high-voltage capability and a compact can-style package with screw terminals for robust power connections.

Designed for industrial power electronics, this part targets inverter circuitry, AC servomotor regenerative circuits and other high-frequency power conversion applications where high ripple handling and long life at elevated temperature are required.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance with a rated voltage of 400 V and ±20% tolerance.
• High-temperature endurance — Rated for continuous operation from −40 °C to +105 °C with a specified load life of 5000 hours at 105 °C under rated ripple conditions.
• Ripple current capability — Supports 18.8 A at 120 Hz and 26.32 A at 10 kHz, enabling use in high-ripple and high-frequency power circuits.
• Screw-terminal mounting — Radial can with screw terminals and M5 nominal bolt engagement (for φ90 case) for secure electrical and mechanical connection.
• Compact high-voltage package — φ90 × 105 mm can dimensions (approx. L: 10.5 cm × D: 9.0 cm) offering high-voltage performance in a reduced footprint compared with larger variants.
• Leakage and insulation — Leakage current after 5 minutes is specified as not more than 3√CV (µA) or 5 mA, whichever is smaller; insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
• Endurance and charge–discharge robustness — Meets specified characteristics after 5000 hours at 105 °C under rated ripple and also after 50 million charge–discharge cycles (ΔV = rated voltage ±0.3, 3 Hz cycle).
• RoHS compliant — Conforms to RoHS directive requirements listed in the series documentation.

Typical Applications

• Industrial inverters — Bulk energy storage and smoothing in inverter front-ends and DC bus circuits where 400 V systems are used.
• AC servomotor systems — Supports regenerative and high-frequency voltage conditions in servo drives and motor control applications.
• Power supplies for industrial equipment — Filtering and energy buffering in high-voltage industrial power supplies and conversion stages.

Unique Advantages

• High ripple handling: Specified ripple current at both low and high frequencies allows reliable operation in high-frequency and high-load environments.
• Long elevated‑temperature life: 5000-hour load life at 105 °C provides predictable aging and maintenance planning for industrial deployments.
• Robust electrical connections: Screw-terminal package with M5 bolt engagement offers secure, low-resistance terminations suited to heavy-current installations.
• Compact high-voltage form factor: φ90 × 105 mm can delivers high capacitance and 400 V rating in a relatively compact package for space-constrained power assemblies.
• Validated endurance behavior: Meets capacitance, tan δ and leakage specifications after extensive charge–discharge cycling and shelf-life testing per series data.
• Regulatory compliance: RoHS compliance supports use in regulated equipment and installations.
