LGGW6391MELC30

The LGGW6391MELC30 is a Nichicon LGG-series aluminum electrolytic capacitor in a snap-in terminal can. It delivers 390 µF capacitance at a 420 V rating with snap-in mounting and a compact φ35 × 30 mm case designed for space-constrained assemblies.

Targeted for general-purpose electronic equipment, this part combines high-voltage capability with specified low- and high-frequency ripple handling and a 2,000-hour endurance at 105°C for reliable operation in demanding environments.

Key Features

• Rated Capacitance and Voltage — 390 µF nominal capacitance at a 420 V rated voltage for high-voltage circuits.
• Snap-in Terminal Package — Radial, can-style snap-in mounting for secure board attachment in tray-packed units.
• Compact LGG Series Size — Ultra-smaller-sized LGG-series case (one rank smaller than LGN) to support equipment downsizing while maintaining performance.
• Ripple Current Capability — Low-frequency ripple current of 1.45 A (120 Hz) and high-frequency ripple current of 2.074 A (100 kHz) to support AC ripple and dynamic load conditions.
• Endurance and Temperature — Rated for 2,000 hours at 105°C; operating temperature range −25°C to 105°C consistent with 400–450 V class parts in the LGG family.
• Leakage and Tolerance — Specified leakage current of 1,210 µA and capacitance tolerance of ±20% (120 Hz, 20°C).
• Regulatory and Packaging — RoHS compliant and shipped in tray packing; status: mass production.

Typical Applications

• General Purpose Electronic Equipment — Suitable where a 420 V, 390 µF snap-in aluminum electrolytic capacitor is required for general-purpose designs.
• Equipment Downsizing — The LGG-series’ smaller case size supports designs that need reduced component footprint without changing capacitor class.
• High-Voltage Assemblies — Provides 420 V rating and defined ripple current specifications for high-voltage circuits within general-purpose systems.

Unique Advantages

• Space-efficient LGG form factor — One-rank-smaller case size compared to LGN supports compact product designs.
• High-voltage capability — 420 V rating enables selection for higher-voltage general-purpose applications.
• Documented ripple performance — Rated ripple currents at 120 Hz and 100 kHz let designers match capacitor selection to expected AC stress.
• Robust thermal endurance — 2,000-hour life at 105°C provides predictable long-term performance under rated conditions.
• Production-ready supply — RoHS compliance, tray packing, and mass-production status ease procurement and assembly planning.
