LNX2G682MSEH

The LNX2G682MSEH is a screw-terminal aluminum electrolytic capacitor designed for extra-high-voltage, high-ripple applications. As part of Nichicon’s LNX series, it delivers high ripple-current capability and long operational life for demanding industrial power electronics.

Engineered for use in industrial power supplies and inverter circuitry, this polarized radial-can capacitor provides high voltage handling, robust screw-terminal connections, and specifications optimized for sustained performance up to +85°C.

Key Features

• Capacitance and Voltage — 6.8 mF (6800 µF) rated at 400 V for energy storage and bulk smoothing in high-voltage power stages.
• High Ripple Current — Rated ripple current: 16.7 A at 120 Hz and 23.38 A at 100 kHz, supporting continuous ripple handling in power conversion circuits.
• Long Operational Life — Specified for 20,000 hours at +85°C when subjected to rated ripple current, enabling extended maintenance intervals in industrial systems.
• Temperature Range and Stability — Operates from −25°C to +85°C; impedance ratio Z(−25°C)/Z(+20°C) ≤ 8 for low-temperature performance.
• Robust Screw-Terminal Mounting — Radial can with screw terminals provides secure electrical and mechanical connections for heavy-current applications.
• Leakage Current Limit — After 5 minutes’ application of rated voltage, leakage current is specified as not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C).
• Construction and Options — Flame-retardant electrolyte versions are available; sleeve marking is white on black for clear identification.
• Physical Size — Body dimensions: L: 17 cm × D: 7.62 cm; maximum seated height 6.693 inch, suitable for vertical mounting with secure brackets.
• Regulatory Compliance — RoHS compliant (2011/65/EU,(EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in industrial rectifiers and power modules where high voltage and continuous ripple are present.
• Inverter Circuitry — DC-link and smoothing capacitor for inverter stages that require sustained ripple-current endurance at elevated temperatures.
• High-Voltage Power Conversion — Filtering and energy buffering in extra-high-voltage conversion systems within industrial equipment.

Unique Advantages

• High ripple endurance: Rated ripple currents at both low and high frequencies (16.7 A @120 Hz, 23.38 A @100 kHz) reduce thermal stress in continuous-operation power stages.
• Extended service life: 20,000-hour endurance at +85°C under rated ripple current supports longer maintenance intervals and predictable lifespan planning.
• Extra-high voltage capability: 400 V rating (series covers 350–550 V) enables use in higher-voltage industrial power designs without sacrificing capacitance.
• Secure mechanical and electrical connections: Screw-terminal radial-can package offers robust mounting and current-carrying capability for heavy-duty applications.
• Low-temperature performance: Specified impedance stability down to −25°C (Z ratio ≤ 8) helps maintain filtering effectiveness in cold environments.
• Compliance and safety options: RoHS compliance plus availability of flame-retardant electrolyte variants address regulatory and safety considerations.
