LGU2G271MELC

The LGU2G271MELC is a Nichicon LGU series snap‑in aluminum electrolytic capacitor specified at 270 µF and 400 V. It is a radial, snap‑in can designed for general‑purpose applications that require high voltage, bulk capacitance and long-term thermal endurance.

Key value comes from its 105°C endurance rating with 3000 hours of life under rated ripple current, RoHS compliance, and compact φ35 × 30 mm package in tray packing for production use.

Key Features

• Snap‑in Radial Package — Radial, can‑type snap‑in termination for secure PCB mounting and robust mechanical retention.
• Rated Capacitance and Tolerance — 270 µF nominal with ±20% tolerance at 120 Hz, 20°C.
• High Voltage Rating — 400 V rated voltage suitable for high‑voltage general‑purpose circuits.
• High‑Temperature Endurance — Specified for 3000 hours at 105°C with D.C. bias plus rated ripple current applied.
• Loss and Leakage — Tangent of loss angle (tan δ) 0.15 measured at 20°C, 120 Hz, and typical leakage current of 980 µA after voltage application.
• Ripple Current Performance — Low‑frequency ripple current 1.22 A (120 Hz) and high‑frequency ripple current 1.745 A (50 kHz) ratings provided for thermal and ripple management.
• Operating Temperature Range — −25°C to +105°C to match higher ambient and power‑dissipation environments.
• Production‑Ready Packaging — Supplied in tray packing and listed as mass production status for volume assembly.
• RoHS Compliant — Complies with RoHS directive requirements.

Typical Applications

• General‑purpose high‑voltage circuits — Provides bulk capacitance at 400 V and 270 µF for designs specified as general purpose.
• Thermally demanding assemblies — Suitable where sustained operation at up to 105°C and 3000‑hour endurance under rated ripple is required.
• PCB snap‑in mounting designs — Radial snap‑in package simplifies installation in applications that use snap‑in cans.

Unique Advantages

• Long‑term thermal reliability: With a 3000‑hour endurance rating at 105°C under rated ripple current, the LGU2G271MELC supports sustained high‑temperature operation.
• High voltage and bulk capacitance: 400 V rating combined with 270 µF nominal capacitance delivers substantial energy storage for high‑voltage general‑purpose needs.
• Defined ripple specifications: Published low‑ and high‑frequency ripple current ratings (1.22 A at 120 Hz, 1.745 A at 50 kHz) allow thermal/ripple budgeting during design.
• Measurable electrical performance: Specified tan δ (0.15 at 20°C, 120 Hz) and leakage current (980 µA) provide clear, testable parameters for verification.
• Production suitability: Tray packing and mass production status streamline procurement and board‑level assembly for volume projects.
• Regulatory compliance: RoHS compliance supports environmentally conscious designs and regulatory requirements.
