LGU2G271MELB

The LGU2G271MELB is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in terminal, radial can package designed for general‑purpose power applications. It provides 270 µF capacitance at a 400 V rating with ±20% tolerance and is supplied in tray packing for production use.

Designed for sustained operation at elevated temperature, this part offers a 3000‑hour endurance at 105°C, low loss (tanδ 0.15 at 20°C/120 Hz for the 400 V class), and significant ripple current capability to support filtering and bulk energy storage in higher‑voltage circuits.

Key Features

• Capacitance & Voltage — 270 µF rated at 400 V with ±20% tolerance, suitable for higher‑voltage DC filtering and bulk capacitance applications.
• Snap‑in Radial Can Package — Snap‑in terminal type in a φ30 × 35 mm can, designed for secure board mounting and stable mechanical retention.
• Endurance at Elevated Temperature — 3000 hours life at 105°C under rated ripple and DC bias conditions, meeting long‑duration thermal stress requirements.
• Low Loss (tanδ) — tanδ of 0.15 (max.) measured at 20°C and 120 Hz for the 315–450 V range, supporting efficient energy storage with reduced dissipation.
• High Ripple Current Capability — Rated ripple current of 1.22 A at 120 Hz (low frequency) and 1.745 A at 50 kHz (high frequency), enabling effective AC ripple handling.
• Leakage Current — Specified leakage current of 980 µA, measured after voltage application per datasheet conditions.
• Operating Temperature Range — Specified for −25°C to +105°C suitable for applications requiring elevated operating temperatures at the 400 V class.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing in circuits operating up to 400 V where robust endurance and ripple handling are required.
• Power supplies — DC link and output filtering in power conversion stages that benefit from high voltage rating and sustained thermal endurance.
• Industrial electronics — Use in higher‑voltage industrial equipment requiring long life at elevated temperatures and reliable ripple current performance.

Unique Advantages

• 400 V rating: Enables deployment in higher‑voltage circuits without stacking or derating.
• Long thermal endurance: 3000 hours at 105°C provides predictable life performance under continuous elevated temperature and ripple stress.
• Efficient energy handling: Low tanδ (0.15 at 120 Hz/20°C) reduces dissipation and supports thermal stability in high‑voltage applications.
• Robust ripple capability: High specified ripple currents at both 120 Hz and 50 kHz support a wide range of switching and line‑frequency conditions.
• Production‑ready packaging: Supplied in tray packing and noted as mass production status for streamlined procurement and assembly.
• Regulatory compliance: RoHS compliance supports use in designs targeting restricted‑substance requirements.
