LNX2W122MSEF

The LNX2W122MSEF from Nichicon is a screw‑terminal aluminum electrolytic capacitor rated 1.2 mF (1200 µF) at 450 V with a ±20% capacitance tolerance. Designed for industrial power applications, it delivers high ripple current capability and extended endurance in a robust radial can with screw terminals.

Engineered for use in industrial power supplies and inverter circuitry, this part offers high ripple handling (4.7 A at 120 Hz, 6.58 A at 100 kHz), a low tanδ of 0.2 (20°C, 120 Hz), and a long rated life of 20,000 hours at 85°C for reliable performance under continuous load.

Key Features

• Electrical Performance — 1.2 mF capacitance at 450 V with ±20% tolerance; low dissipation factor (tanδ 0.2 at 20°C, 120 Hz) for predictable AC behavior.
• High Ripple Current — Rated ripple current of 4.7 A at 120 Hz and 6.58 A at 100 kHz to support heavy AC stress and filtering duties.
• Long Endurance — Lifetime specified as 20,000 hours at 85°C when subjected to rated ripple current, supporting extended service intervals.
• Leakage Control — Specified leakage current of 2200 µA to help manage standby losses and initial charge behavior.
• Screw‑Terminal Package — Radial can with screw terminals (M5 nominal bolt for φ51 size) for secure, high‑current connections and straightforward installation.
• Operating Range & Stability — Category temperature range −25°C to +85°C with impedance stability at low temperature (Z(−25°C)/Z(+20°C) up to 8), suited for typical industrial environments.
• Compliance & Packaging — RoHS compliant and supplied in cardboard packing; mass production status for consistent availability.

Typical Applications

• Industrial Power Supplies — Suited for inverter circuitry and other industrial supply designs requiring high ripple handling and long life.
• High‑Voltage Power Systems — Use where 450 V dielectric strength and extra‑high voltage application capability are required.
• General Purpose Power Filtering — Bulk filtering and energy smoothing in equipment that benefits from a screw‑terminal, high‑capacity capacitor.

Unique Advantages

• High ripple tolerance: 4.7 A (120 Hz) and 6.58 A (100 kHz) ratings reduce thermal stress under heavy AC loading.
• Extended service life: 20,000 hours at 85°C under rated ripple current provides predictable endurance for continuous‑duty applications.
• Robust, serviceable connections: Screw‑terminal mounting (M5 for φ51) enables secure, maintainable high‑current terminations.
• High voltage capability: 450 V rating supports extra‑high voltage applications within the LNX series range.
• Measured dielectric performance: Specified tanδ and leakage values enable engineers to design predictable impedance and loss budgets.
• Regulatory compliance: RoHS compliant construction meets environmental restriction requirements.
