LGG2G271MELB25

The LGG2G271MELB25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGG series, designed for compact, high-voltage applications. It delivers 270 µF capacitance at a 400 V rating with ±20% tolerance and is constructed for general-purpose use in electronic equipment.

Engineered for durability, this part is specified for operation from −25°C to +105°C with a 2000-hour endurance at 105°C, small radial can dimensions (φ30 × 25 mm), and tray packing for mass production assembly processes.

Key Features

• High voltage rating: 400 V rated voltage suitable for high-voltage circuits requiring robust DC capacitance.
• Nominal capacitance and tolerance: 270 µF with ±20% tolerance at 120 Hz, 20°C, providing predictable energy storage and filtering behavior.
• Endurance at elevated temperature: 2000 hours life at 105°C under D.C. bias plus rated ripple current, meeting the LGG series endurance criteria after recovery to 20°C.
• Thermal range and low-temperature performance: Operating range −25°C to +105°C; impedance ratio specification for 400 V types supports use down to −25°C.
• Low loss factor: tanδ specified at 0.15 (max.) for rated voltages up to 420 V, measured at 120 Hz/20°C, indicating controlled dielectric losses.
• Ripple current capability: Rated ripple currents of 1 A at 120 Hz and 1.43 A at 100 kHz, enabling AC ripple handling in power circuits.
• Snap-in radial can package: φ30 × 25 mm radial, snap-in terminal construction for secure board mounting and streamlined assembly; supplied in tray packing for production environments.
• Compliance: RoHS compliant as specified for the LGG series.

Typical Applications

• General-purpose electronic equipment: Provides DC energy storage and smoothing in electronic systems that require a 400 V, 270 µF snap-in capacitor.
• Power conversion modules: Used for bulk filtering and ripple suppression where elevated voltage rating and defined ripple current capability are required.
• Industrial and commercial electronics: Suited to compact designs that benefit from the LGG series' smaller case size for equipment downsizing while retaining 105°C endurance.

Unique Advantages

• High-voltage capability: 400 V rating supports higher-voltage DC rails without stacking multiple components.
• Compact footprint for downsized equipment: φ30 × 25 mm radial can fits tighter layouts—LGG is one rank smaller than LGN in case size—helping reduce enclosure volume.
• Long operating life at temperature: 2000 hours at 105°C under rated conditions provides predictable long-term performance in elevated-temperature environments.
• Measured ripple performance: Specified ripple current at both low and high frequencies (1 A at 120 Hz, 1.43 A at 100 kHz) lets designers size components with confidence.
• Controlled dielectric losses: tanδ max 0.15 (120 Hz, 20°C) supports thermal management and efficiency planning in power circuits.
• Manufacturing-friendly packaging: Tray packing and snap-in terminals simplify placement and wave/flow solder-compatible assembly for high-volume production.
