LNX2G222MSEG

The LNX2G222MSEG is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series, rated 400 V with a nominal capacitance of 2200 µF. It is a polarized, radial can-style capacitor designed for high-ripple, extra-high-voltage applications where long life and reliable DC link performance are required.

Suited for industrial power electronics, the part is specifically targeted at industrial power supplies and inverter circuitry. Key value propositions include high ripple-current capability, extended operational lifetime under rated ripple conditions, and RoHS compliance.

Key Features

• Capacitance & Voltage: 2200 µF nominal capacitance at a rated voltage of 400 V, tolerance ±20% (120 Hz, 20°C).
• High Ripple Current: Designed for heavy ripple loading — 6.8 A at 120 Hz and 9.52 A at 100 kHz — to support demanding power conversion and inverter duties.
• Long-Life Endurance: Rated for 20,000 hours of standard ripple-current application at +85°C, providing extended service life for sustained high-stress operation.
• Operating Temperature Range: Specified from −25°C to +85°C, with low-temperature impedance characteristics (Z(−25°C)/Z(+20°C) = 8) for reliable cold-start behavior.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage is limited to 3√(C·V) µA or 5 mA, whichever is smaller (measured at 20°C).
• Robust Mechanical Package: Screw-terminal, radial can with screw terminals for secure, high-current connections; nominal body dimensions L: 9 × D: 6.35 cm.
• Safety & Compliance Options: Flame-retardant electrolyte versions are available by type; the product is RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk and smoothing capacitors in high-voltage industrial supplies, supporting inverter front-ends and power conversion stages.
• Inverter Circuitry: DC-link and energy-storage applications in inverter systems where high ripple current and voltage endurance are required.
• High-Voltage Power Conversion: Extra-high-voltage applications within the series’ rated range (350–550 V) that demand reliable, long-duration ripple performance.
• General-Purpose Power Electronics: General-purpose use where a high-capacitance, screw-terminal aluminum electrolytic capacitor is needed for robust power handling.

Unique Advantages

• High Ripple Handling: Explicit ripple ratings at both low and high frequencies allow designers to size capacitors confidently for demanding converter and inverter loads.
• Extended Operational Life: 20,000-hour endurance at +85°C under rated ripple current reduces maintenance and replacement frequency in continuous-duty systems.
• Secure Screw-Terminal Interface: Screw-terminal mounting provides reliable, low-resistance connections for high-current bus configurations and easy field servicing.
• Wide Series Voltage Coverage: Part of a series that spans 350–550 V ratings, enabling selection of consistent capacitor technology across different system voltages.
• Environmental Compliance & Safety Options: RoHS compliance and availability of flame-retardant electrolyte types support regulatory needs and enhanced safety requirements.
• Low-Temperature Performance: Defined impedance behavior down to −25°C supports applications that require predictable performance across temperature extremes.
