LNX2W392MSEG

The LNX2W392MSEG is an aluminum electrolytic capacitor in a screw-terminal, radial can package from Nichicon's LNX series. It provides large capacitance (3.9 mF / 3900 µF) at an extra-high voltage rating of 450 V for demanding power applications.

Designed for industrial power electronics, this capacitor targets high-ripple, long-life use cases such as inverter and power-supply circuitry where sustained performance at elevated temperatures is required. It is RoHS compliant and built for robust, polarized DC energy storage and filtering.

Key Features

• High Capacitance: 3.9 mF (3900 µF) nominal capacitance with ±20% tolerance for bulk energy storage and smoothing in high-voltage circuits.
• Extra-High Voltage Rating: 450 V rated voltage suitable for extra-high voltage power-conversion applications.
• Screw Terminal Mounting: Robust radial can with screw terminals for secure, low-impedance connections in high-current assemblies.
• High Ripple Current Capability: Rated ripple current of 11.4 A at 120 Hz and 15.96 A at 100 kHz to support heavy AC ripple conditions.
• Long Operational Life: Endurance specified for 20,000 hours at +85°C when standard ripple current is applied, supporting long-duration deployments under rated conditions.
• Operating Temperature Range: −25 °C to +85 °C for reliable performance across common industrial environments.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is limited to 3√CV (µA) or 5 mA, whichever is smaller.
• Package Size: φ63.5 × 170L (L: 17 × D: 6.35 cm) radial can; screw-terminal form factor accommodates secure mounting and cabling.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing in high-voltage industrial power supplies where sustained ripple handling and long life are required.
• Inverter Circuits: Energy buffering and ripple absorption in inverter circuitry for industrial drives and converters.
• Extra-High Voltage Power Conversion: Filtering and DC link applications that require a 450 V rating and high ripple-current capability.
• General-Purpose High-Reliability Designs: Polarized DC applications that benefit from long endurance at elevated temperature and robust terminal connections.

Unique Advantages

• Large Stored Energy: 3.9 mF capacitance provides substantial bulk storage for smoothing and transient support in high-voltage systems.
• Designed for High Ripple: High-rated ripple currents (11.4 A @120 Hz; 15.96 A @100 kHz) reduce thermal stress and support continuous ripple duty.
• Long Endurance at Elevated Temperature: Specified 20,000-hour life at +85 °C under rated ripple conditions, enabling extended maintenance intervals in industrial deployments.
• Secure Screw-Terminal Interface: Screw terminals facilitate reliable high-current connections and ease of installation and replacement.
• Clear Leakage Limits: Defined leakage current behavior (3√CV µA or 5 mA max after 5 minutes) supports predictable system behavior during commissioning and standby.
• Regulatory Compliance: RoHS conformity supports environmentally restricted product requirements.
