LNX2W123MSEJBN

The LNX2W123MSEJBN from Nichicon is an aluminum electrolytic, screw‑terminal capacitor designed for extra‑high voltage, high‑ripple current applications. It delivers 12,000 µF capacitance at a 450 V rating and is constructed for long operational life under rated ripple conditions.

Targeted at industrial power systems, the LNX series is suited for use in industrial power supplies and inverter circuitry where high ripple endurance and reliability at elevated temperatures are required.

Key Features

• High Capacitance & Voltage: 12,000 µF rated capacitance at 450 V for bulk energy storage and smoothing in high‑voltage power rails.
• Screw Terminal Package: Radial can with screw terminals provides secure, high‑current connections for robust system integration.
• Long Life at Elevated Temperature: Rated for 20,000 hours of standard ripple current operation at +85°C, supporting extended service life in demanding environments.
• High Ripple Current Capability: Rated ripple current of 26.9 A at 120 Hz and 37.66 A at 100 kHz to handle heavy AC ripple and switching loads.
• Wide Operating Temperature Range: Specified for −25°C to +85°C operation to cover typical industrial ambient conditions.
• Polarized Electrolytic: Polarized construction with ±20% capacitance tolerance (120 Hz, 20°C), simplifying selection for power‑supply filtering and energy reservoir duties.
• RoHS Compliant: Meets RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.
• Physical Dimensions: φ90 × 220L package (size listing includes L: 22 × D: 9 cm and maximum seated height 8.661 inch) for systems that require a high‑energy, screw‑terminal can style capacitor.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy storage in industrial power converters where extra‑high voltage rating and long life are required.
• Inverter Circuits: High ripple current capability and screw‑terminal mounting make it suitable for inverter DC links and switching power stages.
• General Purpose Power Systems: Energy reservoir and filtering in general industrial electronic systems that require robust, high‑voltage capacitors.

Unique Advantages

• Designed for High‑Voltage Systems: 450 V rating enables use in extra‑high voltage applications without requiring series stacking of lower‑voltage parts.
• Handles Heavy Ripple Loads: Measured ripple currents of 26.9 A (120 Hz) and 37.66 A (100 kHz) reduce thermal stress and improve performance under switching loads.
• Extended Operational Life: 20,000‑hour endurance at +85°C under rated ripple current supports longer maintenance intervals and predictable lifetime planning.
• Secure Mechanical and Electrical Connections: Screw terminal construction simplifies installation and provides reliable connection for high‑current paths.
• Compliance‑Ready: RoHS conformity supports regulatory requirements for restricted substances in industrial products.
