LNY2W123MSEJBB

The LNY2W123MSEJBB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNY series. It delivers 12,000 µF at a 450 V rating in a radial can with screw terminals, offering a high-capacitance solution for compact equipment designs.

Designed for general-purpose use, the part combines high ripple-handling capability and a rated operating range of −40 °C to +85 °C with a load life specification of 2,000 hours at 85 °C, making it suitable where durable high-voltage capacitance and secure terminal mounting are required.

Key Features

• High Capacitance & Voltage: 12,000 µF nominal capacitance at a 450 V rating provides substantial energy storage for high-voltage circuits.
• Screw-Terminal Package: Radial can with screw terminals enables secure mechanical and electrical connections for assemblies requiring robust terminals.
• Thermal & Life Performance: Rated operating temperature −40 °C to +85 °C with a specified load life of 2,000 hours at 85 °C when rated ripple current is applied.
• High Ripple Current Capability: Rated ripple current of 26 A at 120 Hz and 36.4 A at 10 kHz supports applications with substantial AC ripple on the DC bus.
• Polarized Design & Tolerance: Polarized capacitor with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Electrical Safety Characteristics: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket and voltage proof tested at AC 2500 V for 1 minute between terminal and bracket.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose equipment — Use in systems that require high-voltage, high-capacitance components for energy storage or filtering where a screw-terminal package is preferred.
• Equipment downsizing — Suited for designs focused on reducing overall system volume while retaining high capacitance at 450 V.
• High-ripple environments — Suitable where significant ripple current is present, supported by rated ripple currents of 26 A (120 Hz) and 36.4 A (10 kHz).
• Screw-terminal mounting systems — For assemblies that require secure screw connections and a radial can form factor.

Unique Advantages

• Substantial energy density: 12,000 µF at 450 V provides large stored charge in a single component, reducing the need for multiple parallel capacitors.
• Robust ripple handling: High ripple current ratings at both low and high frequencies help maintain performance under demanding AC-loading conditions.
• Designed for compact assemblies: Specifically noted as suited for equipment downsizing, enabling smaller system footprints without sacrificing capacitance.
• Durability under elevated temperature: 2,000-hour load-life rating at 85 °C offers predictable longevity for thermal-stressed applications.
• Clear identification: Marked with white lettering on a black sleeve for easy part recognition and verification during assembly.
• Regulatory conformity: RoHS compliance supports use in environments requiring restriction-of-hazardous-substance conformance.
