LNX2G103MSEHBB

The LNX2G103MSEHBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNX series, rated at 10,000 µF and 400 V. It is a radial can with screw terminals designed for general-purpose high-voltage power applications.

Engineered for high ripple environments, this part delivers elevated ripple-current capability and extended endurance at elevated temperature, making it suitable for industrial power supplies and inverter circuitry where high-voltage smoothing and long operating life are required.

Key Features

• Capacitance & Voltage: 10,000 µF (10 mF) nominal capacitance with a 400 V rated voltage and ±20% tolerance.
• High Ripple Current: Low-frequency ripple current 22.7 A at 120 Hz and high-frequency ripple current 31.78 A at 100 kHz to support demanding power-conversion workloads.
• Long Endurance: Rated for 20,000 hours of standard ripple-current operation at +85°C, providing extended service life in continuous-duty applications.
• Screw-Terminal, Radial Can Package: Robust screw-terminal mounting and radial can package simplify installation and mechanical retention for heavy-current connections.
• Operating Range: Specified for −25°C to +85°C operation to match common industrial ambient conditions.
• Leakage Current & Polarization: Polarized design with leakage current specified at up to 5,000 µA (5 mA) after initial application of rated voltage.
• Physical Size & Packaging: Body diameter φ76.2 mm with length 220 mm (L: 22 × D: 7.62 cm); supplied in cardboard packing for mass-production distribution.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• Industrial power supplies & inverter circuitry: Provides high-voltage energy storage and smoothing where high ripple current and long life are required.
• High-voltage power filtering: Suited for general-purpose filtering and bulk energy storage in equipment operating at or near 400 V DC.
• Power conversion modules: Supports applications that demand sustained ripple performance and robust screw-terminal connections for high-current paths.

Unique Advantages

• High ripple endurance: Rated ripple-current figures for both low and high frequencies, combined with 20,000-hour endurance at 85°C, reduce the need for frequent replacement in continuous-duty systems.
• High-voltage capability: 400 V rating enables use in higher-voltage DC buses and converter topologies without series stacking.
• Secure screw-terminal connections: Screw terminals provide a reliable, low-resistance connection for heavy-current wiring and simplify assembly in power racks and panels.
• Clear performance limits: Specified leakage current, tolerance, and temperature range allow straightforward design margins and predictable behavior under rated conditions.
• Regulatory compliance and production readiness: RoHS compliance and mass-production availability support volume sourcing and environmental requirements.
