LGU2W221MELB

The LGU2W221MELB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, designed for general‑purpose power applications requiring high voltage handling and sustained ripple endurance. This radial, can‑style capacitor delivers 220 µF at 450 V with polarized snap‑in mounting and is supplied in tray packing for board‑level installation.

Engineered for continuous operation up to 105°C, the LGU2W221MELB targets power assemblies where long life and stable performance under rated ripple current are required.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C).
• High Voltage Rating — Rated voltage 450 V for high‑voltage power systems.
• Ripple Current Endurance — Low‑frequency ripple current 1.12 A at 120 Hz and high‑frequency ripple current 1.602 A at 50 kHz, specified for sustained operation.
• Thermal Endurance — Qualified for 3000 hours at 105°C under rated conditions (endurance specification from LGU series).
• Operating Temperature Range — −25°C to 105°C, suitable for elevated ambient environments within the rated voltage range.
• Leakage Current — Specified leakage current of 940 µA (measured after voltage application per datasheet conditions).
• Package & Mounting — Radial, can — snap‑in terminal type (φ30 × 35 mm), designed for secure chassis/board installation; tray packing for handling and assembly.
• Regulatory — RoHS compliant.

Typical Applications

• General‑purpose power supplies — Bulk smoothing and energy storage in high‑voltage power rails where 450 V rating is required.
• Industrial power equipment — Filtering and ripple management in industrial control and power conversion modules operating up to 105°C.
