LNX2H122MSEGBN

The LNX2H122MSEGBN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNX series, rated at 1.2 mF (1200 µF) and 500 V. Designed for high-ripple and extra-high-voltage applications, it delivers robust energy storage and reliable performance in demanding industrial power systems.

Typical use cases include industrial power supplies and inverter circuitry where high ripple current handling, long operational life at elevated temperatures, and screw-terminal mechanical robustness are required.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a 500 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current — Rated ripple current of 4.8 A at 120 Hz and 6.72 A at 100 kHz to support inverter and high-stress power applications.
• Long Life at Elevated Temperature — Specified lifetime of 5000 hours at +85°C under rated conditions for this 500 V part, supporting extended field operation.
• Operating Temperature Range — Functional from −25°C to +85°C for broad industrial ambient conditions.
• Screw Terminal Package — Radial can with screw terminals for secure, low-resistance connections and simplified assembly in power modules.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20°C).
• RoHS Compliant — Conforms to RoHS directive requirements for restricted substances.
• Optional Flame-Retardant Electrolyte — Flame retardant electrolyte version available for applications that require it.

Typical Applications

• Industrial Power Supplies — Energy storage and smoothing in high-voltage industrial supply rails where sustained ripple capability is necessary.
• Inverter Circuitry — Bulk capacitance and ripple handling for inverter front-ends and DC link networks in power conversion equipment.
• Extra‑High‑Voltage Systems — Components for systems that require extra-high voltage ratings up to 500 V with reliable long-term performance.
• General Purpose High-Voltage Designs — General-purpose applications that call for a robust radial can screw-terminal capacitor with high capacitance and voltage rating.

Unique Advantages

• High Voltage Capability: 500 V rating enables use in extra-high-voltage power rails without stacking multiple capacitors.
• Designed for High Ripple: Measured ripple current ratings at both 120 Hz and 100 kHz improve thermal and electrical stability under heavy AC stress.
• Extended Operational Lifetime: 5000 hours at +85°C for this 500 V part provides predictable endurance for industrial applications.
• Secure Screw-Terminal Mounting: Screw terminals provide reliable mechanical and electrical connections suitable for high-current installations.
• Standards-Conscious Design: RoHS compliance and availability of a flame-retardant electrolyte option support regulatory and safety considerations.
