Overview of LNX2G392MSEG – 3900 µF, 400 V Screw-Terminal Aluminum Electrolytic Capacitor

The LNX2G392MSEG is an aluminum electrolytic, screw-terminal capacitor in Nichicon's LNX series, offering 3.9 mF capacitance at a 400 V rating. Designed for industrial power electronics, it targets DC-link, inverter and converter circuits where high ripple handling and long operating life are required.

Key value comes from high ripple-current capability, extended endurance at elevated temperature, and a screw-terminal radial can package that supports secure bolted connections in heavy-duty power designs.

Key Features

  • Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a 400 V rated voltage and ±20% tolerance.
  • High Ripple Current — Rated ripple current of 11 A at 120 Hz and 15.4 A at 100 kHz to support demanding power-conversion loads.
  • Long Life & Endurance — Specified for long life: 20,000 hours at +85°C under rated ripple conditions per series endurance data.
  • Temperature Range — Operates from −25 °C to +85 °C, suitable for industrial ambient profiles covered by the series specifications.
  • Screw-Terminal, Radial Can Package — Robust screw-terminals for secure bolted connections and simplified field installation in power assemblies.
  • Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C) per series specification.
  • Safety & Compliance — Flame-retardant electrolyte type available; RoHS compliant (2011/65/EU, (EU)2015/863).
  • Form Factor — Radial, can-style package with screw terminals; physical size listed as L: 15 × D: 6.35 cm for this part.

Typical Applications

  • Industrial Power Supplies — DC-link and bulk energy smoothing for inverter circuitry and industrial converters where sustained ripple and voltage endurance are needed.
  • Power Conversion Systems — Support for high-voltage converter stages requiring robust capacitance at 400 V and high ripple tolerance.
  • Heavy-Duty Power Electronics — Use in motor drives, frequency converters and similar equipment that demand secure screw-terminal connections and extended life at elevated temperature.

Unique Advantages

  • Extended Operational Lifetime: Rated for 20,000 hours at +85 °C with rated ripple current, reducing replacement frequency in continuous-duty installations.
  • High Ripple Capability: Specified ripple currents of 11 A (120 Hz) and 15.4 A (100 kHz) support high-stress power-electronics environments.
  • High Voltage Handling: 400 V rating provides headroom for DC-link and high-voltage converter applications within the series' voltage range.
  • Secure Mechanical Termination: Screw-terminal radial can package enables reliable bolted connections for high-current, high-vibration systems.
  • Regulatory and Safety Options: RoHS compliance and availability of flame-retardant electrolyte types support regulatory needs and safety-conscious designs.

Why Choose LNX2G392MSEG?

The LNX2G392MSEG combines high capacitance and a 400 V rating with screw-terminal robustness and proven series endurance to serve demanding industrial power designs. Its rated ripple current values and 20,000-hour endurance at +85 °C make it suitable for continuous-duty DC-link and inverter applications where reliability and long service life are priorities.

Engineers specifying this part will benefit from a radial can, screw-terminal form factor that simplifies mounting and power connections, RoHS compliance, and series-level performance data that supports predictable behavior in high-voltage power electronics systems.
