LNX2G122MSEFBB

The LNX2G122MSEFBB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series, optimized for high-voltage, high-ripple applications. With a 400 V rating and 1.2 mF (1200 µF) capacitance in a radial can with screw terminals, it is aimed at industrial power systems that require robust DC-link and energy smoothing components.

Designed for continuous operation up to +85°C and long-term reliability, this part delivers high ripple-current capability, controlled loss characteristics, and a 20,000 hour life at 85°C to support demanding power-conversion and inverter circuitry.

Key Features

• High voltage rating – Rated voltage of 400 V for extra-high-voltage applications and industrial power systems.
• Large capacitance – 1.2 mF (1200 µF) nominal capacitance with ±20% tolerance, providing bulk energy storage and smoothing.
• Screw-terminal mounting – Radial can package with screw terminals (M5 terminal pitch for φ51) for secure, low-impedance connections in power assemblies.
• High ripple-current capability – 4.5 A at 120 Hz (low frequency) and 6.3 A at 100 kHz (high frequency) to handle substantial AC ripple in power-conversion circuits.
• Low dissipation factor – Specified tan δ of 0.2 supports stable performance under AC stress.
• Long operational life – Endurance rating of 20,000 hours at +85°C when operated within rated ripple and voltage conditions.
• Controlled leakage – Characteristic leakage current of 2,070 µA (measured condition per product specification).
• Operating temperature range – Usable from −25°C to +85°C for many industrial environments.
• RoHS compliant – Conforms to RoHS requirements as stated for the LNX series.
• Compact form factor – Physical size φ51 × 80L mm (approx. 5.1 × 8.0 cm) for high-capacitance in a compact screw-terminal can.

Typical Applications

• Industrial power supplies and inverters – Suited for inverter circuitry and industrial power supplies that require high-voltage, high-ripple DC-link capacitors.
• Extra-high-voltage power systems – Designed for use in systems where higher-than-standard voltages and robust ripple handling are required.
• General-purpose high-ripple circuits – Applicable where large capacitance and sustained ripple current capacity improve power stability and system reliability.

Unique Advantages

• Designed for sustained ripple stress – High low- and high-frequency ripple ratings (4.5 A at 120 Hz, 6.3 A at 100 kHz) reduce heating and extend service life under AC loading.
• Long-life specification – 20,000-hour endurance at 85°C supports long-term deployments and maintenance cycles in industrial equipment.
• Screw-terminal reliability – Robust M5-compatible terminals provide dependable electrical and mechanical connections for power assemblies.
• High-voltage energy storage – 400 V rating combined with 1200 µF capacitance provides significant bulk energy capacity in a compact package.
• Predictable electrical behavior – Specified tan δ and leakage current let designers model losses and insulation performance accurately.
• Regulatory compliance – RoHS-compliant construction supports environmental requirements for industrial applications.
