LGG2W681MELC50

The LGG2W681MELC50 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGG series. It provides 680 µF capacitance at a 450 V rating in a compact, radial can snap-in package designed for general-purpose high-voltage applications.

Designed as an ultra-smaller-sized option within the LGG family, this part is suited to equipment downsizing and mass-production assemblies, supplied in tray packing and built for long-term operation up to 105°C.

Key Features

• Rated Capacitance: 680 µF with ±20% tolerance (specified at 120 Hz, 20°C), providing bulk energy storage for smoothing and filtering.
• High Voltage Capability: Rated for 450 V, suitable for high-voltage circuits within the 160–450 V range supported by the LGG series.
• Temperature and Endurance: Operating temperature range of −25°C to +105°C with endurance specified as 2000 hours at 105°C under rated DC bias plus ripple current.
• Snap-in Radial Can Package: Snap-in mounting (radial, can - snap-in) for secure PCB installation in power assemblies.
• Ripple Current Performance: Specified ripple currents of 1.91 A at 120 Hz and 2.731 A at 100 kHz for both low- and high-frequency filtering scenarios.
• Compact Size & Production Ready: Physical size φ35 × 50 mm (L: 5 × D: 3.5 cm) and supplied in tray packing for mass production deployment.
• RoHS Compliant: Meets RoHS directive requirements as noted in the LGG series documentation.

Typical Applications

• High-voltage power supplies — Bulk smoothing and energy storage in power conversion stages requiring a 450 V-rated electrolytic capacitor.
• Industrial power equipment — Filtering and ripple control in industrial converters and modules where robust ripple handling and elevated temperature endurance are required.
• Space-constrained power modules — Compact LGG series sizing and snap-in mounting support equipment downsizing and dense PCB layouts.

Unique Advantages

• Compact, downsizing-friendly form factor: One rank smaller case size within the LGG family, helping reduce enclosure and PCB footprint.
• High-voltage, high-capacitance combination: 680 µF at 450 V enables substantial energy storage in high-voltage circuits without increasing component count.
• Dual-frequency ripple specifications: Rated ripple currents provided for both 120 Hz and 100 kHz, supporting a range of filtering and decoupling needs.
• Long-duration thermal endurance: 2000 hours at 105°C under rated conditions for reliability in elevated-temperature environments.
• Production-ready packaging: Tray packing and mass production availability simplify procurement and assembly for volume manufacturing.
• Regulatory compliance: RoHS compliance aligns with common environmental requirements for commercial and industrial equipment.
