LNX2G122MSEFBN

The LNX2G122MSEFBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNX series. It delivers 1,200 µF capacitance at a 400 V rating in a robust radial can with screw terminals, designed for general-purpose and industrial power applications.

Engineered for high-ripple, extra-high-voltage use, this part targets industrial power supplies and inverter circuitry that demand long life and reliable performance at elevated temperatures.

Key Features

• Electrical Performance — 1,200 µF nominal capacitance with ±20% tolerance and a 400 V rated voltage suitable for high-voltage power circuits.
• Low Loss (tan δ) — Specified tan δ 0.2 (measurement per datasheet conditions), providing controlled dissipation for power applications.
• High Ripple Capability — Rated ripple current of 4.5 A at 120 Hz and 6.3 A at 100 kHz to support demanding AC ripple environments.
• Long Endurance — 20,000 hours rated life at +85°C under rated ripple current, enabling long-term reliability in continuous-duty installations.
• Screw Terminal Package — Radial can with screw terminals (φ51 case, nominal bolt M5) for secure, low-resistance connections and ease of assembly.
• Operating Range & Size — Operational temperature range −25°C to +85°C; physical dimensions φ51 × 80 mm length (L: 8 cm × D: 5.1 cm).
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to ≤ 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C).
• Compliance & Packaging — RoHS compliant; supplied in cardboard packing suitable for mass production handling.

Typical Applications

• Industrial Power Supplies — Used for bulk energy storage and smoothing in industrial supplies where 400 V platforms and high ripple are present.
• Inverter Circuitry — Suited to DC link and smoothing roles in inverter systems requiring extra-high-voltage, high-ripple components.
• General Purpose Power Electronics — Applicable where long-life, high-voltage electrolytic capacitance is needed in rugged screw-terminal packaging.

Unique Advantages

• High-voltage, high-capacitance in a compact can — 1,200 µF at 400 V provides substantial energy storage for power-conversion stages without unconventional packaging.
• Designed for continuous ripple duty — Specified ripple current ratings at 120 Hz and 100 kHz support designs with significant AC content across the capacitor.
• Extended operational life — 20,000 hours endurance at 85°C under rated ripple current gives predictable long-term performance for industrial deployments.
• Screw-terminal robustness — M5-compatible screw terminals enable secure mechanical and electrical connections in high-current assemblies.
• Measured leakage and loss characteristics — Clear leakage current limits and tan δ specification support predictable thermal and loss budgeting in designs.
• RoHS compliant and production-friendly packaging — Environmentally compliant material set and cardboard packing aligned with mass-production handling.
