The LGG2W121MELA25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGG series, offering 120 µF capacitance at a 450 V rating in a compact φ25 × 25 mm can. Designed for general-purpose use, this component delivers high-voltage bulk capacitance in a space-saving snap-in package suitable for applications that require reliable performance under elevated temperature and ripple conditions.

Key performance characteristics include low leakage, defined ripple current capability at both low and high frequencies, RoHS compliance, and a 2000-hour endurance rating at 105°C—attributes that support robust operation in demanding power circuits and equipment down-sizing efforts.

Key Features

• Electrical Rating — 120 µF nominal capacitance with ±20% tolerance and a 450 V rated voltage, providing high-voltage bulk capacitance for power circuits.
• Ripple and Leakage — Rated ripple currents of 690 mA at 120 Hz and 986.7 mA at 100 kHz, with specified leakage current of 690 µA, enabling stable filtering under AC ripple conditions.
• Temperature and Endurance — Operating range of −25°C to +105°C and endurance of 2000 hours at 105°C when subjected to DC bias plus rated ripple current, supporting sustained operation at elevated temperatures.
• Compact Snap‑in Package — Radial can with snap-in terminals in a φ25 × 25 mm size, designed to save PCB space and simplify board-level mounting.
• Regulatory and Production — RoHS compliant and available in tray packing with mass production status for reliable supply and straightforward procurement.
• Polarized Construction — Standard polarized aluminum electrolytic design for correct orientation in DC circuits.

Typical Applications

• General-Purpose Power Circuits — Bulk energy storage and smoothing where 450 V rating and 120 µF capacitance are required to stabilize DC rails.
• High-Voltage Filtering — Filtering and ripple suppression in high-voltage power converters and related equipment that must tolerate defined ripple currents.
• Equipment Down-Sizing — Compact snap-in φ25 × 25 mm package suited to designs focused on reducing component footprint while maintaining high-voltage capability.
