LGGW6271MELA40

The LGGW6271MELA40 is a snap‑in terminal type aluminum electrolytic capacitor in Nichicon’s LGG series, providing 270 µF capacitance at a 420 V rated voltage. It is designed for general‑purpose power applications that require high voltage handling, compact packaging and reliable ripple performance.

With a φ25 × 40 mm can and a snap‑in radial package, this part targets equipment downsizing while delivering measured endurance and defined ripple capability across low and high frequency conditions.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a 420 V rated voltage, with a tolerance of ±20% (–20% to +20%).
• Snap‑in Radial Can Package — Snap‑in terminal, radial can design for secure PCB mounting and mechanical stability in power assemblies.
• Compact Footprint for Downsizing — φ25 × 40 mm size; LGG series is specified as one rank smaller case than the LGN series to support reduced equipment size.
• Ripple Current Handling — Rated ripple current of 1.25 A (120 Hz) for low‑frequency conditions and 1.7875 A (100 kHz) for high‑frequency conditions, supporting smoothing and filtering under varying load spectra.
• Leakage and Endurance — Specified leakage current of 1010 µA and an endurance rating of 2000 hours at 105 °C when biased with DC plus rated ripple current.
• Operating Temperature — Rated for operation from –25 °C to +105 °C (consistent with 400–450 V category temperature limits in the series datasheet).
• Regulatory & Production — RoHS compliant; supplied in tray packing and available in mass production quantities.

Typical Applications

• General‑purpose power electronics — Bulk smoothing and filtering in high‑voltage circuits where 270 µF at 420 V is required.
• Compact power supplies — Small‑case footprint supports equipment downsizing while maintaining high‑voltage capacitance and ripple capability.
• Industrial equipment — Robust snap‑in mounting and defined endurance at 105 °C for sustained operation in industrial power assemblies.

Unique Advantages

• High‑voltage capability: 420 V rating enables use in circuits that require elevated DC voltage handling without series stacking.
• Dual‑spectrum ripple performance: Specified ripple currents at both 120 Hz and 100 kHz address real‑world low and high frequency ripple environments.
• Space‑saving form factor: φ25 × 40 mm can and LGG series one‑rank smaller case help reduce board area and overall equipment volume.
• Defined thermal endurance: 2000 hours at 105 °C provides measurable lifecycle expectations for thermal stress planning.
• Manufacturing readiness: Tray packing and mass production status facilitate integration into volume assembly processes.
• Standards compliance: RoHS compliance supports regulatory requirements for material content.
