LGW2W271MELA50

The LGW2W271MELA50 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon’s LGW series. It delivers 270 µF bulk capacitance at a 450 V rating with snap-in radial (can) packaging designed for general-purpose applications that require high ripple current handling and high-voltage capability.

Key value propositions include high ripple endurance, a long 3000-hour rated life at 105 °C, and RoHS compliance—making this part suited for production environments where sustained performance and regulatory compliance are required.

Key Features

• Capacitance & Tolerance — 270 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C.
• High Voltage Rating — Rated for 450 V to support high-voltage bulk energy storage needs.
• High Ripple Current Capability — Rated ripple current of 1.74 A at low frequency (120 Hz) and 2.488 A at high frequency (50 kHz), backed by frequency coefficient data in the LGW series.
• Endurance — Rated for 3000 hours of operation at 105 °C with DC bias plus rated ripple current applied.
• Operating Temperature Range — Specified for −25 °C to +105 °C for the 400–450 V range.
• Leakage Current — Specified leakage current of 1040 µA after standard voltage application conditions.
• Package & Mounting — Snap-in radial can, physical size φ25 × 50 mm (L: 5 × D: 2.5 cm), supplied in tray packing for production handling.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General Purpose Power Circuits — Provides bulk capacitance and high ripple current endurance for general-purpose designs requiring high-voltage capability.
• High-Ripple Environments — Designed for applications where sustained ripple current and long life at elevated temperature are required.
• Production Assembly — Snap-in radial format and tray packing facilitate board mounting and handling in mass production contexts.

Unique Advantages

• High ripple endurance: Rated ripple current and 3000-hour endurance at 105 °C support continuous operation under ripple-stressed conditions.
• High-voltage capability: 450 V rating enables use in higher-voltage circuits without stacking or series arrangements.
• Compact snap-in package: φ25 × 50 mm can with snap-in terminals provides robust mechanical mounting while saving PCB area compared with larger alternatives.
• Predictable leakage performance: Specified leakage current (1040 µA) after standard voltage application offers verifiable baseline for design leakage budgets.
• Production-friendly packaging: Tray packing supports efficient handling and throughput in mass production lines.
• RoHS compliance: Meets RoHS directive requirements for restricted substances in electronic equipment.
