LNY2G123MSEJBN

The LNY2G123MSEJBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNY series, offering high bulk capacitance in a robust radial can with screw terminals. Designed for general-purpose applications, it targets equipment requiring high-voltage, high-capacitance components while supporting equipment downsizing efforts.

Key value propositions include a 12,000 µF capacitance at 400 V, a rated operating temperature range of –40 °C to +85 °C, and a specified load life of 2000 hours at 85 °C, combined with RoHS compliance.

Key Features

• High Capacitance: 12,000 µF (12 mF) provides substantial bulk energy storage for high-voltage circuits.
• High Rated Voltage: 400 V rated voltage for use in high-voltage power applications.
• Screw Terminal Mounting: Radial can with screw terminals simplifies secure mechanical and electrical connections for high-current systems.
• Operating Temperature Range: –40 °C to +85 °C for reliable performance across wide ambient conditions.
• Load-Life Specification: 2000 hours at 85 °C under rated ripple current, supporting sustained operation at elevated temperature.
• Ripple Current Capability: 26 A at 120 Hz and 36.4 A at 10 kHz, enabling effective handling of AC ripple in high-current circuits.
• Physical Size: φ90 × 155 L (L: 15.5 × D: 9 cm) radial can suitable for compact, high-capacitance implementations.
• Tolerance and Polarization: ±20% capacitance tolerance (120 Hz, 20 °C) and polarized design.
• RoHS Compliant: Meets applicable RoHS requirements for restricted substances.

Typical Applications

• General-purpose power assemblies: Bulk capacitance in high-voltage, high-capacity circuits where a screw-terminal capacitor is preferred.
• Equipment down-sizing projects: High capacitance in a compact radial can supports smaller power modules and cabinets.
• High-current AC ripple environments: Systems that require robust ripple current capability at both low and high frequencies.

Unique Advantages

• Substantial bulk energy storage: 12,000 µF at 400 V reduces the need for multiple parallel components for equivalent capacitance.
• High-voltage rating: 400 V capability supports higher-voltage DC buses without series stacking.
• Durability at elevated temperature: 2000-hour load life at 85 °C provides predictable aging under rated ripple stress.
• High ripple current handling: 26 A (120 Hz) and 36.4 A (10 kHz) ratings help maintain voltage stability under heavy ripple conditions.
• Secure screw-terminal connections: Mechanical robustness and reliable electrical contact for demanding installations.
• Regulatory alignment: RoHS compliance supports use in product lines subject to restricted-substance requirements.
