LNX2W182MSEGBN

The LNX2W182MSEGBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNX series, rated at 1.8 mF (1800 µF) and 450 V. It is designed for high-ripple, extra-high-voltage applications and is suited to industrial power supply and inverter circuitry where long life and high reliability are required.

Key value propositions include high ripple-current capability, extended operational lifetime under rated ripple at elevated temperature, and robust screw-terminal mounting for secure power connections.

Key Features

• Capacitance and Voltage: 1.8 mF (1800 µF) nominal capacitance with a 450 V rated voltage and ±20% tolerance, suitable for high-voltage energy storage and smoothing.
• High Ripple Capability: Ripple current ratings of 6.1 A at 120 Hz and 8.54 A at 100 kHz provide the capability to handle substantial AC stress in power conversion stages.
• Long Operating Life: Specified for 20,000 hours when subjected to the rated ripple current at +85°C, supporting long-term reliability in continuous-duty industrial environments.
• Temperature Range: Operates from −25°C to +85°C, covering typical industrial ambient conditions.
• Mounting and Package: Screw terminal, radial can package with screw terminals for secure, low-resistance power connections in heavy-current applications.
• Polarized Electrolytic Construction: Polarized aluminum electrolytic design for bulk capacitance in DC link and filter applications.
• Safety and Environmental: Flame-retardant electrolyte types are available; the part is RoHS compliant (2011/65/EU,(EU)2015/863).
• Mechanical Dimensions: Size L × D: 9 × 6.35 cm with a maximum seated height of 3.543 inches, providing a compact footprint for a high-capacitance, high-voltage capacitor.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and DC-link smoothing in industrial converters and power supply modules.
• Inverter Circuitry: Filtering and ripple handling in inverter stages where high voltage and high ripple current capability are required.
• Power Conversion Systems: Energy buffering and smoothing in high-voltage power conversion and motor drive electronics.

Unique Advantages

• High-voltage capability: 450 V rating supports higher-voltage DC-link designs without series stacking.
• Designed for high ripple: Specified ripple current at both low and high frequencies helps reduce thermal stress and improve system stability.
• Extended operational life: 20,000-hour endurance at +85°C under rated ripple current reduces maintenance and replacement frequency.
• Secure screw-terminal mounting: Robust mechanical and electrical connection for heavy-current applications and industrial environments.
• RoHS-compliant and flame-retardant options: Environmental compliance with available flame-retardant electrolyte enhances application safety and regulatory alignment.
