LNX2W472MSEHBB

The LNX2W472MSEHBB is a screw-terminal large-can aluminum electrolytic capacitor from Nichicon's LNX series. It delivers 4.7 mF capacitance at a 450 V rated voltage and is configured as a polarized, radial can package with screw terminals for robust power connections.

Engineered for industrial power electronics, the part is suited to inverter circuitry and industrial power supplies where high ripple current, extra-high voltage capability and long life at elevated temperature are required.

Key Features

• Electrical Performance — 4.7 mF capacitance with ±20% tolerance and a 450 V rated voltage for high-voltage DC link and filtering applications.
• High Ripple Capability — Rated ripple current of 12.9 A at 120 Hz and 18.06 A at 100 kHz to support heavy AC ripple and switching-power applications.
• Long Life & Reliability — Designed for 20,000 hours of rated ripple-current operation at +85°C, supporting extended maintenance intervals in continuous-duty systems.
• Temperature Range — Operates from −25°C to +85°C to cover typical industrial environments.
• Robust Mechanical Design — Radial can with screw terminals for secure electrical connections and dependable mechanical mounting; nominal dimensions L: 15 × D: 7.62 cm.
• Safety & Compliance Options — Flame-retardant electrolyte types available; RoHS compliant (2011/65/EU, (EU)2015/863).
• Polarized Device — Designed as a polarized aluminum electrolytic capacitor for DC applications.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and filtering in industrial PSUs where high voltage and ripple endurance are required.
• Inverter Circuitry — DC link and smoothing for inverter stages, benefiting from high ripple current capability and extra-high voltage rating.
• Power Electronics Modules — Energy buffering and decoupling in high-power converters and motor-drive systems.
• General Purpose Power Systems — Applications that require robust, long-life electrolytic capacitance in a screw-terminal can package.

Unique Advantages

• High-Ripple Endurance: Rated ripple current values at both low and high frequencies (12.9 A at 120 Hz; 18.06 A at 100 kHz) reduce thermal stress in switching environments.
• Extra-High Voltage Capability: 450 V rating enables use in higher-voltage DC-link and smoothing applications without series stacking.
• Extended Operational Life: 20,000 hours at +85°C under rated ripple conditions supports long duty cycles and lowers replacement frequency.
• Secure Screw-Terminal Mounting: Screw terminals provide reliable low-resistance connections and simplified integration into power assemblies.
• Regulatory Compliance and Safety Options: RoHS compliance and the availability of flame-retardant electrolyte types help meet environmental and safety requirements.
• Compact Large-Can Form Factor: Radial, screw-terminal can with specified L × D dimensions for predictable mechanical integration in power enclosures.
