LNX2G682MSEJ

The LNX2G682MSEJ is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series, delivering 6.8 mF capacitance at a 400 V rating in a radial can with screw terminals. It is designed for high-voltage, high-ripple applications and general-purpose industrial power designs where long operational life and robust terminations are required.

Key value propositions include elevated ripple-current capability, extended lifetime at elevated temperature (20,000 hours at +85°C under rated ripple conditions), and a stout screw-terminal package suited to demanding power system connections.

Key Features

• Capacitance & Tolerance — 6.8 mF (6,800 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• High Voltage Rating — Rated for 400 VDC to support extra-high-voltage power conversion stages.
• Long Endurance — Specified for 20,000 hours of endurance at +85°C when operated with the standard ripple current, supporting extended service life in high-stress power applications.
• High Ripple Current Capability — Rated ripple current of 16.3 A at 120 Hz and 22.82 A at 100 kHz, enabling use where substantial AC ripple or switching currents occur.
• Screw-Terminal, Radial Can Package — Robust screw terminals (radial can) with φ90×130 mm overall size and M5-class terminal hardware for secure electrical and mechanical connections.
• Operating Temperature Range — Specified for −25°C to +85°C operation to match common industrial ambient profiles.
• Leakage and Marking — Leakage current limited to 3√CV (µA) or 5 mA (whichever is smaller) after 5 minutes at rated voltage; sleeves are marked with white text on black.
• RoHS Compliance — Compliant to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Energy smoothing and bulk storage for high-voltage industrial supplies and control equipment.
• Inverter Circuitry — Bulk capacitance and ripple handling in inverter DC-link and power-conversion stages.
• High-Ripple, High-Voltage Power Modules — Use where sustained ripple currents and elevated DC voltages demand long-life, high-capacitance solutions.
• General-Purpose High-Voltage Designs — General purpose energy stabilization and filtering in equipment requiring a 400 V-rated electrolytic capacitor.

Unique Advantages

• Extended Cycle Life: Rated for 20,000 hours at +85°C under standard ripple current, providing predictable long-term performance in continuous-duty applications.
• Robust Ripple Handling: High ripple-current ratings (16.3 A at 120 Hz; 22.82 A at 100 kHz) reduce thermal stress and improve reliability in switching supply environments.
• Secure Screw-Terminal Connectivity: Radial can with screw terminals and M5-class bolt interface delivers mechanically secure, low-resistance connections for power wiring.
• High DC Voltage Capability: 400 V rating supports extra-high-voltage sections of power conversion systems without requiring series arrangements of lower-voltage parts.
• Industry-Ready Compliance: RoHS-compliant construction aligns with common regulatory requirements for industrial equipment.
• Clear Identification: Printed white-on-black sleeve marking simplifies part identification during assembly and maintenance.
