LNX2G183MSEK

The LNX2G183MSEK is an aluminum electrolytic capacitor in Nichicon’s LNX series, built in a screw-terminal radial can package. It provides 18,000 µF capacitance at a 400 V rating and is designed for high-ripple, long-life applications.

Suited for industrial power supply and inverter circuitry applications, this part combines high ripple current capability with extended endurance to support demanding power-conversion designs.

Key Features

• Electrolytic core and rating — 18,000 µF nominal capacitance with a 400 V rated voltage; polarized design with ±20% capacitance tolerance at 120 Hz, 20°C.
• High ripple capability — Standard ripple current of 33 A at 120 Hz and 46.2 A at 100 kHz to support DC-link and smoothing duties in high-current power circuits.
• Long operational life — Endurance specified as 20,000 hours at +85°C when subjected to the standard ripple current, supporting longer maintenance intervals in continuous-use systems.
• Robust screw-terminal package — Radial can with screw terminals (φ100 case, 220 mm length); terminal hardware designed for secure, high-current connections (φ100 nominal bolt diameter M8 in series dimensions).
• Operating range and leakage — Rated for operation from −25°C to +85°C; leakage current specified as not more than 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at 20°C.
• Regulatory compliance — RoHS compliant for environmental and regulatory compatibility.

Typical Applications

• Industrial power supplies — Bulk smoothing and energy buffering in industrial supplies where sustained ripple handling and long life are required.
• Inverter circuitry — DC-link and smoothing capacitor for inverter modules that demand high ripple capability and a 400 V rating.
• High-voltage power conversion — Applications requiring a high-voltage electrolytic solution with large capacitance and reliable endurance at elevated temperatures.

Unique Advantages

• High ripple tolerance: Rated ripple currents at both low and high frequency (33 A @ 120 Hz; 46.2 A @ 100 kHz) reduce thermal stress in DC-link and smoothing roles.
• Extended service life: 20,000-hour endurance at +85°C under rated ripple current supports longer deployment between replacements and predictable lifecycle planning.
• Secure screw-terminal connectivity: Radial can with screw terminals and φ100 terminal hardware (M8 nominal bolt) enables reliable mechanical and electrical connections for high-current installations.
• High-capacitance form factor: 18,000 µF in a φ100 × 220 mm package provides substantial energy storage in a compact high-voltage footprint.
• RoHS compliance: Meets RoHS directive requirements for environmentally regulated designs.
