Overview of LNX2L392MSEJ – Screw‑Terminal Aluminum Electrolytic Capacitor, 3900 µF, 550 V

The LNX2L392MSEJ is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNX series, offering 3.9 mF (3900 µF) capacitance at a 550 V rating. Designed for industrial power applications, it targets inverter circuitry and other high‑voltage, high‑ripple environments where long operating life and high reliability are required.

Its screw‑terminal radial can package and high ripple current capability support robust power filtering and energy storage in industrial power supplies, while RoHS compliance addresses regulatory requirements.

Key Features

  • Capacitance & Voltage — 3.9 mF (3900 µF) rated at 550 V with ±20% tolerance (measured at 120 Hz, 20°C), providing high bulk energy storage for high‑voltage systems.
  • High Ripple Current — Rated ripple current of 12.5 A at 120 Hz and 17.5 A at 100 kHz, enabling effective smoothing in inverter and power‑supply circuits.
  • Endurance / Long Life — Designed for endurance at elevated temperature: rated for 5000 hours at +85°C when subjected to DC bias plus rated ripple current (specific to 500 V and 550 V parts).
  • Operating Temperature & Low‑Temp Stability — Operating range −25°C to +85°C with an impedance ratio Z(−25°C)/Z(+20°C) of 8, maintaining performance across the stated temperature window.
  • Mounting & Package — Screw terminal, radial can with screw terminals for secure mechanical and electrical connections in industrial assemblies; physical size: L: 15 × D: 9 cm and maximum seated height 5.906 inches.
  • Series Options — Series supports extra‑high voltage applications (350–550 V range) and extended size options up to φ100; flame‑retardant electrolyte types are available within the series.
  • Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

  • Industrial Power Supplies — Bulk energy storage and smoothing for inverter power stages and high‑voltage DC link capacitors.
  • Motor Drives — Energy buffering and ripple suppression in inverter‑driven motor control systems.
  • High‑Voltage Power Electronics — Filtering and decoupling in extra‑high voltage power assemblies where 550 V rating is required.

Unique Advantages

  • High Voltage Capability: Rated at 550 V, enabling use in extra‑high voltage power systems without series stacking.
  • High Ripple Handling: Substantial ripple current ratings at both low and high frequencies reduce heating and support continuous operation under ripple stress.
  • Proven Endurance: Specified lifetime of 5000 hours at +85°C for 500 V and 550 V parts under rated ripple conditions, allowing predictable maintenance intervals and design planning.
  • Robust Mechanical Termination: Screw terminal radial can simplifies installation and provides secure electrical connections for industrial assemblies.
  • Temperature Performance: Wide operating range from −25°C to +85°C with specified low‑temperature impedance behavior, supporting reliable operation across typical industrial environments.
  • Regulatory Compliance: RoHS compliance supports use in designs requiring restricted‑substance adherence.

Why Choose LNX2L392MSEJ?

The LNX2L392MSEJ combines high capacitance and a 550 V rating with strong ripple current capability and a screw‑terminal package to meet the demands of industrial power supplies, inverter circuits, and other high‑voltage power electronics. Its specified endurance at elevated temperature and quantified low‑temperature impedance characteristics make performance predictable for engineers designing robust systems.

This part is well suited for designers seeking a high‑voltage aluminum electrolytic solution with secure mechanical termination, series options for larger sizes or flame‑retardant electrolyte types, and RoHS compliance for regulatory alignment.
