LNT2G123MSEJBN

The LNT2G123MSEJBN is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNT series designed for general-purpose power applications. It combines high capacitance (12,000 µF) with a 400 V rated voltage and a robust radial can with screw terminals for secure, high-current connections.

Engineered for demanding industrial and power-conversion environments, this part delivers high ripple-current handling, long endurance at elevated temperature, and broad operating conditions to support bulk energy storage, smoothing and DC-link duties.

Key Features

• High Capacitance: 12,000 µF nominal capacitance for bulk energy storage and smoothing in power systems.
• 400 V Rated Voltage: Designed for high-voltage DC applications that require substantial capacitance at elevated voltages.
• High Ripple Current Handling: Low‑frequency ripple current 38.3 A at 120 Hz and high‑frequency ripple current 53.62 A at 100 kHz, enabling robust handling of AC components on DC rails.
• Endurance at Elevated Temperature: Rated life of 5,000 hours at +105°C when operated under specified conditions.
• Electrical Loss Performance: Tangent of loss angle (tan δ) 0.2 measured at 20°C, 120 Hz, supporting stable performance under AC stress.
• Leakage Current: Specified leakage current of 5,000 µA after voltage application, consistent with high-capacitance, high-voltage electrolytic behavior.
• Mechanical and Mounting: Radial can with screw terminals (M5 for φ90 diameter) for secure bolted connections; nominal size φ90 × 220 mm (L), packaged in cardboard packing for shipping.
• Operating Range: Polarized device rated for operation from −25°C to +105°C.
• Capacitance Tolerance: −20% to +20% at 120 Hz, 20°C.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy storage on high-voltage DC rails where large capacitance and high ripple handling are required.
• DC-Link and Inverter Systems: DC-link smoothing for motor drives and power converters that demand high ripple current capability and elevated voltage rating.
• UPS and Energy Storage Modules: Bulk charge storage and voltage stabilization in uninterruptible power supplies and mid-range energy storage subsystems.

Unique Advantages

• Substantial Energy Storage in a Single Can: 12,000 µF at 400 V provides significant stored energy for smoothing and hold‑up without requiring parallel modules.
• High Ripple Capacity: Rated ripple currents (38.3 A at 120 Hz, 53.62 A at 100 kHz) reduce thermal stress and support reliable operation under heavy AC loading.
• Long High‑Temperature Life: 5,000 hours at 105°C supports prolonged operation in hot industrial environments and designs with elevated internal temperatures.
• Secure Screw‑Terminal Mounting: Radial can with screw terminals enables robust, low-resistance connections suitable for high-current assemblies.
• Wide Operating Temperature Window: −25°C to +105°C accommodates a wide range of industrial ambient conditions.
• Manufacturer Proven Series: Part of Nichicon’s LNT series with series-level specifications for load life and voltage range, providing predictable, documented performance.
