LNY2G123MSEJBB

The LNY2G123MSEJBB is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNY series, offering high capacitance in a radial can with screw terminals. Designed for general‑purpose power applications, it provides bulk energy storage and high ripple handling where downsizing and high voltage capability are required.

Key electrical and mechanical attributes include a 12,000 µF nominal capacitance at 400 V, a –40 °C to 85 °C operating range, and a rated life of 2000 hours at 85 °C, making it suitable for robust industrial and power‑supply environments.

Key Features

• High Capacitance: 12,000 µF nominal capacitance with ±20% tolerance (120 Hz, 20 °C), providing substantial bulk energy storage for smoothing and hold‑up applications.
• 400 V Rated Voltage: Rated for 400 V operation to support high‑voltage power rails and industrial power supplies.
• Screw Terminal Mounting: Radial can with screw terminals for secure, low‑resistance connections and straightforward panel or bracket mounting.
• High Ripple Current Capability: 26 A at 120 Hz (low frequency) and 36.4 A at 10 kHz (high frequency), enabling effective handling of large AC ripple currents in power conversion circuits.
• Endurance and Temperature Performance: Load life of 2000 hours at 85 °C; rated operating temperature range from –40 °C to +85 °C for demanding environments.
• Leakage and Dissipation: Leakage current specified at 5000 µA; tangent of loss angle (tan δ) 0.25 measured at 20 °C, 120 Hz.
• Mechanical Size and Packaging: φ90 × 155 mm (diameter × length), supplied in cardboard packing; radial can with screw terminals and optional brackets for mounting.
• Compliance and Production Status: RoHS compliant and in mass production from Nichicon.

Typical Applications

• Industrial Power Supplies: Bulk storage and smoothing on high‑voltage rails where high capacitance and 400 V rating are required.
• Power Conversion Equipment: Support for inverters, converters and UPS systems that demand high ripple current capability and long endurance at elevated temperatures.
• Equipment Downsizing Projects: High capacitance-per-volume option to help reduce overall system footprint while maintaining required energy storage.

Unique Advantages

• High Energy Density: 12,000 µF at 400 V delivers significant bulk capacitance for smoothing and hold‑up without increasing component count.
• Robust Ripple Handling: Rated ripple currents of 26 A (120 Hz) and 36.4 A (10 kHz) reduce thermal stress under heavy AC loading.
• Secure Screw‑Terminal Connections: Screw terminals enable reliable electrical and mechanical connections suitable for industrial assemblies.
• Operation Across Wide Temperatures: –40 °C to +85 °C rating and 2000 h life at 85 °C provide predictable performance in challenging thermal environments.
• Standards‑Oriented Specifications: Leakage current and tan δ specified with measurement conditions (20 °C, 120 Hz), aiding predictable design verification and validation.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products where restricted substance requirements apply.
