LGGW6391MELA50

The LGGW6391MELA50 is a snap-in terminal type aluminum electrolytic capacitor from Nichicon’s LGG series. It delivers 390 µF capacitance at a 420 V rating in a compact φ25 × 50 mm can, designed for general-purpose high-voltage applications.

Engineered for higher-temperature operation and production readiness, this part supports operation from −25 °C to 105 °C, a rated life of 2000 hours at 105 °C, and is supplied in tray packing for mass production environments.

Key Features

• Core Electricals — 390 µF nominal capacitance with a 420 V rated voltage and tolerance of −20% to 20%, suitable for high-voltage smoothing and energy storage in general-purpose designs.
• High-Temperature Endurance — Rated for continuous operation to 105 °C with a specified lifetime of 2000 hours at 105 °C when biased with DC plus rated ripple current.
• Snap-In Mounting — Snap-in terminal, radial can package simplifies board installation for through-hole assemblies and offers mechanical stability in power assemblies.
• Compact Footprint — Ultra-smaller-sized LGG series casing at φ25 × 50 mm supports equipment downsizing compared to larger LGN cases.
• Ripple Performance — Specified ripple current: 1.45 A at 120 Hz and 2.074 A at 100 kHz, enabling predictable ripple handling across common frequency ranges.
• RoHS Compliance & Production Pack — RoHS-compliant construction and tray packing for streamlined integration into high-volume manufacturing.

Typical Applications

• General-purpose power systems — Use where a 420 V, 390 µF capacitor is required for smoothing, bulk storage or decoupling in general-purpose circuits.
• Compact equipment designs — Suited for downsized equipment thanks to the LGG series’ smaller case size compared with LGN.
• High-temperature assemblies — Applicable in designs requiring operation up to 105 °C and a rated 2000-hour endurance at that temperature.
• Production and OEM builds — Tray packing and mass-production readiness support consistent supply for volume manufacturing.

Unique Advantages

• High-voltage capability: 420 V rating provides headroom for high-voltage systems while maintaining a compact form factor.
• Temperature-rated reliability: Specified operation to 105 °C and a 2000-hour endurance at that temperature support long-term performance in hotter environments.
• Predictable ripple handling: Published ripple current values at 120 Hz and 100 kHz allow designers to assess thermal and ripple stress for specific operating conditions.
• Space-saving package: φ25 × 50 mm snap-in can in the LGG series helps reduce board area compared with larger series options.
• Manufacturing-ready: Tray packing and mass-production availability simplify procurement and assembly for volume production.
• Regulatory compliance: RoHS-compliant construction aligns with common environmental requirements for electronic assemblies.
