LNY2W122MSEFBN

The LNY2W122MSEFBN from Nichicon is a screw-terminal, radial-can aluminum electrolytic capacitor designed for higher-capacitance, 85°C operation. Built for general-purpose electrical equipment and equipment downsizing efforts, this part provides 1.2 mF of polarized capacitance at a 450 V rating.

Key value comes from its high-voltage capability, robust ripple-current handling, and long load-life specification, making it suitable where compact high-capacitance storage and reliable high-voltage performance are required.

Key Features

• Capacitance & Voltage — 1.2 mF rated capacitance with a 450 V DC rating, specified tolerance of ±20% (–20% to +20%).
• Package & Mounting — Screw terminal, radial can package designed for secure bolted connections and mechanical stability in installation.
• Operating Temperature — Specified for –40°C to +85°C operation, matching the LNY series category temperature range.
• Load Life — Endurance rated at 2000 hours with applied ripple current at 85°C, supporting sustained operation under rated ripple conditions.
• Ripple Current Capability — Rated ripple current of 6 A at 120 Hz and 8.4 A at 10 kHz, suitable for applications with substantial AC ripple components.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) μA or 5 mA, whichever is smaller (measurement at 20°C), per the datasheet.
• Physical Size — Body dimensions approximately L: 7.5 × D: 5.1 cm for space planning in compact equipment layouts.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electrical equipment — Suitable where a polarized, high-voltage electrolytic capacitor is required for energy storage within general-purpose systems.
• Equipment downsizing projects — Higher capacitance in a compact screw-terminal can supports efforts to reduce overall equipment footprint.
• High-voltage designs up to 450 V — Applicable in circuits and assemblies that require capacitance rated for up to 450 V DC.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage power assemblies without stepping up to specialized capacitor types.
