LGN2W331MELB40

The LGN2W331MELB40 is a 330 µF, 450 V aluminum electrolytic capacitor in a snap-in radial can designed for general-purpose electronic applications. It delivers compact, high-voltage capacitance with a snap-in mounting for secure PCB installation and is part of Nichicon’s LGN series engineered for elevated temperature endurance.

Key value comes from its 105°C rating and 3000-hour ripple-current endurance at 105°C, making it suitable where sustained high-temperature ripple performance and a reduced case size (one rank smaller than LGU) are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 450 V rated voltage, providing high-voltage bulk capacitance in a single component.
• High-Temperature Endurance — Rated for operation from −25°C to +105°C with endurance specified as 3000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Performance — Specified ripple current of 1.38 A at 120 Hz and 1.973 A at 100 kHz, supporting sustained ripple loading across a range of frequencies.
• Compact Snap-In Package — Radial, can-type snap-in mounting for robust PCB attachment; one rank smaller case size than LGU while maintaining performance.
• Tolerance & Polarization — Polarized capacitor with capacitance tolerance of −20% to +20% (±20%).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Leakage & Stability Characteristics — Designed to meet series specifications for leakage current and tan δ after endurance and shelf-life conditions as defined in the LGN series datasheet.

Typical Applications

• General-purpose power electronics — Suitable where high-voltage bulk capacitance and sustained ripple endurance at elevated temperature are required.
• Industrial equipment — Used in general-purpose industrial electronic assemblies that require compact, high-voltage electrolytic capacitance.
• High-voltage designs within LGN series range — An option for designs needing a 450 V, 330 µF snap-in capacitor with proven 105°C endurance.

Unique Advantages

• High-temperature ripple endurance: Rated to withstand 3000 hours of rated ripple current at 105°C, reducing the need for overspecifying components for heat-stressed designs.
• Compact footprint: One rank smaller case size than LGU offers space savings on PCBs without sacrificing rated voltage or capacitance.
• Dual-frequency ripple specs: Published ripple current values at both 120 Hz and 100 kHz enable confident selection for a range of switching and line-frequency environments.
• Snap-in mounting reliability: Radial snap-in can provides secure mechanical retention for through-hole assemblies and robust board-level mounting.
• Regulatory conformity: RoHS compliance supports use in regions and projects requiring restricted-substance adherence.
