LNX2G392MSEHBB

The LNX2G392MSEHBB is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNX series, rated 3.9 mF (3900 µF) at 400 V with ±20% capacitance tolerance. Designed for high-ripple, extra-high-voltage applications, it targets industrial power electronics such as inverter circuitry and high-voltage power supplies.

Key value comes from its high ripple-current capability, extended endurance at elevated temperature, and a robust screw‑terminal radial can package suited for heavy-duty power systems.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance at a 400 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• High Ripple Current — 10.5 A low-frequency ripple current rating at 120 Hz and 14.7 A high-frequency ripple current rating at 100 kHz, enabling sustained ripple handling in power conversion circuits.
• Long Endurance at Elevated Temperature — Life rating of 20,000 hours at +85°C when subjected to the standard ripple current, supporting extended service in thermally demanding installations.
• Electrical Loss and Leakage — Specified tangent of loss angle (tanδ) 0.2 at 20°C and 120 Hz; leakage current specified at 3740 µA for this part.
• Robust Screw-Terminal Construction — Radial can with screw terminals (M5 nominal bolt for the φ76.2 case) for secure, low-resistance connections in heavy-current applications.
• Operating Range — Rated for operation from −25°C to +85°C and supplied in cardboard packing for mass production handling.
• RoHS Compliant — Meets RoHS directive requirements as stated for the LNX series.

Typical Applications

• Industrial Power Supplies — Provides bulk energy storage and ripple smoothing for high-voltage industrial supply rails.
• Inverter Circuitry — Suited for DC link and filter duties in inverter systems where high ripple current and voltage endurance are required.
• High-Voltage Power Conversion — Useful in extra-high-voltage converter modules and power conditioning equipment that demand sustained ripple performance.
• General Purpose Industrial Electronics — Applicable where a high-voltage, high-capacitance, long-life electrolytic capacitor is needed for reliable operation.

Unique Advantages

• High ripple capability: Rated ripple currents of 10.5 A (120 Hz) and 14.7 A (100 kHz) reduce stress on the capacitor in demanding power conversion loads.
• Extended high-temperature life: 20,000 hours endurance at +85°C provides predictable aging and service life for long‑running installations.
• Robust mechanical termination: Screw terminals and a radial can package offer secure, low-impedance connections for high-current assemblies.
• Controlled electrical characteristics: Specified tanδ (0.2 at 20°C/120 Hz) and defined leakage current enable predictable performance in filter and DC link designs.
• Large form factor for energy storage: φ76.2×100L case (L:10 cm, D:7.62 cm / height 3.937 in) provides significant capacitance and energy density in a single component.
• Regulatory compliance: RoHS status ensures compatibility with current environmental directives.
