LGG2G271MELA35

The LGG2G271MELA35 is a Nichicon LGG series aluminum electrolytic capacitor with snap-in terminals, offering 270 µF capacitance at 400 V rated voltage. It is an ultra-smaller-sized, snap-in can designed for general-purpose electronic applications, suited to equipment downsizing while maintaining high-voltage performance.

Key performance attributes include a maximum tanδ of 0.15 (measured at 20°C, 120 Hz), rated ripple current capabilities at both low and high frequencies, a leakage current spec, and a 2000‑hour endurance at 105°C. The part is RoHS compliant and supplied in tray packing for mass production use.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a 400 V rated voltage, ±20% tolerance, suitable for high-voltage general-purpose applications.
• Snap‑in Terminal Package — Radial, can-type snap-in mounting for secure PCB attachment and robust mechanical connection.
• Compact, Ultra‑Smaller Size — φ25 × 35 mm case (L: 3.5 × D: 2.5 cm), specified as one rank smaller case size in the LGG series to aid equipment downsizing.
• Low Loss (tanδ) — Maximum tanδ of 0.15 at 20°C, 120 Hz, supporting stable performance in AC ripple environments.
• Ripple Current Capability — 1000 mA at 120 Hz (low frequency) and 1430 mA at 100 kHz (high frequency) to handle applied ripple under rated conditions.
• Leakage Current — Specified leakage current of 980 µA (measured after rated voltage application), enabling predictable bias behavior.
• High‑Temperature Endurance — 2000 hours at 105°C under DC bias plus rated ripple current with defined limits for capacitance change, tanδ, and leakage current.
• Operating Temperature Range — Specified operation from −25°C to +105°C (for 400 V ratings), supporting a wide range of environments.
• RoHS Compliant & Production Ready — Meets RoHS requirements and is available in tray packing for mass production deployment.

Typical Applications

• General‑purpose electronics — For designs requiring 270 µF at 400 V with snap‑in mounting in space‑constrained assemblies.
• Power filtering and smoothing — Used where controlled tanδ, specified leakage, and defined ripple current handling are required for DC bias applications.
• High‑temperature environments — Applicable in equipment that must meet endurance requirements at elevated operating temperatures up to 105°C.

Unique Advantages

• High voltage capability: 400 V rating enables use in higher-voltage circuits while maintaining a compact footprint.
• Designed for downsizing: One rank smaller case size compared with previous LGN series options, helping reduce overall equipment volume.
• Dual-frequency ripple handling: Ripple current ratings given for both 120 Hz and 100 kHz allow predictable performance across low and high frequency ripple conditions.
• Proven endurance at 105°C: 2000 hour life specification under DC bias plus rated ripple current supports long-term reliability in demanding thermal conditions.
• Measured loss and leakage specs: Specified tanδ (0.15 at 20°C/120 Hz) and leakage current (980 µA) provide verifiable electrical behavior for design validation.
• Production-ready packaging: Tray packing and mass production status simplify BOM planning and volume assembly processes.
