LGN2V391MELB35

The LGN2V391MELB35 is a Nichicon LGN series aluminum electrolytic capacitor in a snap‑in radial can designed for general‑purpose power applications. It provides 390 µF capacitance at a 350 V rating with polarization and is built for sustained high‑temperature operation up to 105°C.

Engineered to withstand 3000 hours of rated ripple current at 105°C, this smaller‑sized LGN part (one rank smaller than LGU) is suitable where durable ripple endurance, compact radial snap‑in mounting, and RoHS compliance are required.

Key Features

• Capacitance & Voltage: 390 µF nominal capacitance with a 350 V rated voltage for high‑voltage DC applications.
• High‑Temperature Endurance: Rated for operation to 105°C with a guaranteed lifetime of 3000 hours at 105°C under rated ripple current.
• Ripple Current Capability: Specified ripple current performance of 1.3 A at 120 Hz and 1.859 A at 100 kHz for sustained AC ripple handling.
• Snap‑in Radial Can Package: Snap‑in mounting and radial can construction provide robust PCB retention and simplified assembly for power modules and assemblies.
• Polarized Electrolytic: Polarized aluminum electrolytic construction with capacitance tolerance of −20% to +20%.
• Physical Footprint: Compact dimensions (L: 3.5 × D: 3 cm) and reduced case size relative to LGU series for tighter layouts.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Supplies: Bulk smoothing and ripple suppression where a 350 V rated capacitor and sustained ripple endurance at elevated temperatures are required.
• Power Conversion Modules: DC link or energy storage in converters and inverters that demand high ripple current capability and long high‑temperature life.
• Industrial Electronics: Use in general industrial equipment requiring a polarized, snap‑in radial capacitor with reliable performance to 105°C.

Unique Advantages

• Proven High‑Temperature Life: 3000 hours endurance at 105°C under rated ripple current delivers predictable long‑term performance in hot environments.
• Compact Case Size: One rank smaller than the LGU series enables denser packing and reduced board space without sacrificing ripple handling.
• Measured Ripple Ratings: Published ripple current values at both 120 Hz and 100 kHz support design decisions across low and high frequency applications.
• Robust Mounting: Snap‑in radial can design facilitates secure mechanical retention and straightforward assembly into power assemblies and chassis.
• Clear Electrical Limits: Polarized construction with ±20% capacitance tolerance and defined leakage/impedance characteristics for predictable circuit behavior.
• RoHS‑Compliant: Meets RoHS requirements for environmentally regulated designs.
