LNY2W182MSEFBN

The LNY2W182MSEFBN is an aluminum electrolytic capacitor in a screw-terminal radial can designed to deliver high-voltage bulk capacitance in a compact package. With a rated capacitance of 1.8 mF (1800 µF) at 450 V and a φ51 × 95L form factor, it is suited for equipment downsizing where high voltage handling and reliable ripple performance are required.

Built for general-purpose power applications, this Nichicon LNY-series part combines high capacitance, screw-terminal mounting and a specified load life to provide predictable performance in demanding thermal and ripple-current environments.

Key Features

• High Capacitance & Voltage: 1.8 mF (1800 µF) nominal capacitance with a 450 V rated voltage for high-voltage bulk energy storage.
• Screw Terminal Package: Radial can with screw terminals (nominal bolt M5 for φ51) for secure, low-impedance connections in chassis-mounted designs.
• Load Life and Endurance: Specified load life of 2000 hours when rated ripple current is applied at 85 °C, with post-test requirements for capacitance, tan δ and leakage current.
• Ripple Current Capability: Rated ripple current of 7.9 A at 120 Hz and 11.06 A at 10 kHz to support AC ripple handling in power circuits.
• Operating Temperature Range: –40 °C to +85 °C to accommodate a wide range of operating environments.
• Leakage Current Specification: Series-level leakage current limit after 5 minutes is not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C).
• Safety & Insulation: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute between terminal and bracket.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing in power supplies and power conversion modules where 450 V ratings are required.
• Compact industrial equipment: Designs targeting equipment downsizing that need high capacitance in a φ51 × 95L footprint.
• High-voltage filtering: AC ripple attenuation and DC link filtering in high-voltage circuits that demand sustained ripple current capability.

Unique Advantages

• High-voltage bulk capacitance: 1.8 mF at 450 V provides significant stored energy density for high-voltage DC link and filtering functions.
• Robust ripple handling: Specified ripple currents of 7.9 A (120 Hz) and 11.06 A (10 kHz) support continuous ripple loading in power electronics.
• Designed for compact installations: φ51 × 95L (L: 9.5 × D: 5.1 cm) package helps reduce system footprint while maintaining high capacitance.
• Screw-terminal reliability: Radial can with M5-compatible screw terminals delivers secure mechanical and electrical connections for chassis-mounted applications.
• Measured endurance: 2000-hour load-life rating at 85 °C under ripple stress provides a documented performance baseline for thermal and lifetime planning.
• Regulatory conformity: RoHS compliance supports use in designs targeting regulated markets.
