LGG2W271MELB30

The LGG2W271MELB30 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGG series, rated 450 V with 270 µF capacitance. It is a polarized, radial can (snap‑in) capacitor designed for general-purpose high-voltage smoothing and energy storage in compact equipment.

Engineered for space-conscious designs, this 105°C-rated, ultra-smaller-sized part supports elevated ripple currents and a 2000-hour endurance at 105°C, making it suitable for mass-production assemblies where reliability and compact footprint are priorities.

Key Features

• High Voltage Capability — Rated voltage 450 V, suitable for high-voltage power circuits requiring stable bulk capacitance.
• Capacitance and Tolerance — 270 µF with ±20% tolerance at 120 Hz, 20°C for predictable filtering performance.
• Ripple Current Performance — 1.05 A at 120 Hz and 1.5015 A at 100 kHz to handle AC ripple in high-voltage power stages.
• Loss Angle (tan δ) — tan δ up to 0.20 (measured at 20°C, 120 Hz), providing a specified dissipation factor for thermal and performance planning.
• Leakage Current — Specified leakage current of 1040 µA for design margining and initial power-loss calculations.
• Operating and Endurance Ratings — Operating range −25°C to +105°C with 2000 hours endurance at 105°C under rated conditions.
• Compact Snap‑in Package — φ30 × 30 mm can with snap‑in terminals and tray packing to support automated assembly and mass production.
• RoHS Compliant — Meets RoHS directive requirements for environmental conformity.

Typical Applications

• High‑Voltage Power Supplies — Bulk smoothing and energy storage for DC link and high-voltage supply rails where 450 V rating is required.
• Industrial Power Systems — Filtering and ripple suppression in industrial converters and equipment operating within the −25°C to +105°C range.
• Compact Equipment Designs — Suited for equipment downsizing thanks to the LGG series’ ultra-smaller case size and snap‑in mounting.

Unique Advantages

• High‑voltage, high-capacitance combination — 450 V rating with 270 µF enables substantial energy storage in high-voltage circuits without increasing part count.
• Designed for elevated ripple — Specified ripple current at both 120 Hz and 100 kHz supports a range of switching and line-frequency conditions.
• Long endurance at operating temperature — 2000 hours at 105°C offers predictable life performance for continuous high-temperature applications.
• Space-efficient snap‑in package — φ30 × 30 mm can and snap‑in terminals help reduce PCB area and simplify through-hole assembly.
• Production-ready packaging — Tray packing and mass production status streamline procurement and automated assembly integration.
• Regulatory compliance — RoHS compliance supports environmental and regulatory requirements in commercial products.
