LNX2L392MSEJBN

The LNX2L392MSEJBN is a screw-terminal, radial can aluminum electrolytic capacitor in Nichicon’s LNX series, rated 3.9 mF (3900 µF) at 550 V with ±20% tolerance. It is optimized for extra-high voltage, high-ripple applications and is suited to industrial power supplies and inverter circuitry where robust DC link and smoothing capacitance is required.

Key value comes from its high ripple current capability, defined leakage and loss characteristics, and long-endurance specification for 550 V parts—providing predictable performance in demanding power systems. The unit ships in cardboard packing and is RoHS compliant for production use.

Key Features

• Electrical Performance — 3.9 mF capacitance with a 550 V rated voltage and ±20% tolerance, providing substantial energy storage for high-voltage power circuits.
• High Ripple Capability — Rated ripple currents of 12.5 A at 120 Hz (low frequency) and 17.5 A at 100 kHz (high frequency) to support heavy AC ripple in power conversion and inverter stages.
• Loss and Leakage — Specified tangent of loss angle (tan δ) of 0.2 and a measured leakage current of 4390 µA, with tan δ measured at 120 Hz and 20°C per series specification.
• Endurance & Reliability — For 550 V parts the endurance rating is 5000 hours at +85°C under specified ripple conditions, reflecting series-level long-life design intent.
• Robust Mechanical Package — Radial can with screw terminals (φ90 × 150L), terminal bolt nominal diameter M5 for secure connections and easy integration into power assemblies.
• Operating Environment — Rated for operation from −25°C to +85°C and provided in cardboard packing for mass-production supply chains.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Power Supplies (Inverter Circuitry) — Supports DC link/smoothing and high-ripple filtering where inverter stages generate substantial AC ripple.
• High-Voltage Power Conversion — Provides bulk capacitance and energy storage for extra-high-voltage converters and related equipment.
• General-Purpose High-Voltage Systems — Suited to systems requiring polarized, high-voltage aluminum electrolytic capacitance with screw-terminal mounting for robust connections.

Unique Advantages

• High Voltage Handling: 550 V rating enables use in extra-high-voltage power architectures without series stacking.
• High Ripple Endurance: Defined ripple current ratings (12.5 A @120 Hz and 17.5 A @100 kHz) reduce the need for oversized parallel capacitors in high-ripple designs.
• Predictable Loss and Leakage: Specified tan δ (0.2) and measured leakage current (4390 µA) give clear electrical sizing and thermal planning margins.
• Durability in Production: Endurance rating of 5000 hours at 85°C for 550 V parts supports reliable lifetime planning in industrial applications.
• Screw-Terminal Robustness: Radial can with M5 nominal bolt terminals simplifies secure panel or busbar connections in power assemblies.
• RoHS Compliant & Production-Ready: Cardboard-packed for mass production and conforms to RoHS requirements for managed supply chains.
