LGG2G391MELA45

The LGG2G391MELA45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGG series, offering a 390 µF capacitance at a 400 V rating in a compact φ25 × 45 mm can. Designed for general‑purpose high‑voltage applications, this snap‑in radial package supports equipment downsizing while providing reliable high‑temperature endurance.

Key Features

• High Voltage Rating: 400 V rated voltage suited for high‑voltage DC applications within the LGG series rated voltage range (160–450 V).
• Capacitance and Tolerance: 390 µF nominal capacitance with a tolerance of −20% to +20% (±20%), providing predictable bulk energy storage.
• Compact Snap‑In Package: Radial, can‑type snap‑in mounting in a φ25 × 45 mm size (L: 4.5 × D: 2.5 cm) for secure board attachment and reduced footprint.
• Temperature and Endurance: Operating temperature range −25°C to +105°C and rated endurance of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability: Rated ripple current of 1.4 A at 120 Hz and 2.002 A at 100 kHz, supporting common AC ripple conditions in power applications.
• Polarized Electrolytic: Polarized design for DC filtering and energy storage functions.
• RoHS Compliant: Manufactured in compliance with RoHS requirements.
• Series Advantages: LGG series offers an ultra‑smaller 105°C snap‑in option, with one rank smaller case size than the LGN series to help shrink equipment size.

Typical Applications

• High‑voltage power supplies: 400 V rating and substantial capacitance make the LGG2G391MELA45 suitable for DC smoothing and energy storage in high‑voltage supplies.
• DC‑link filtering: Snap‑in mounting and ripple current performance support DC‑link filtering in inverters and power conversion modules.
• Industrial power electronics: Compact 105°C‑rated package and 2000 h endurance at 105°C meet demands of industrial equipment where board space and thermal robustness matter.

Unique Advantages

• Compact high‑voltage solution: One rank smaller case size in the LGG series helps reduce PCB footprint while maintaining a 400 V rating and 390 µF capacitance.
• High‑temperature endurance: Rated for 2000 hours at 105°C, delivering predictable life performance in thermally demanding environments.
• Robust ripple handling: Specified ripple currents at both 120 Hz and 100 kHz provide designers with validated performance across low and high frequency ripple conditions.
• Secure mechanical mounting: Snap‑in radial can simplifies assembly and provides reliable board retention for heavy‑duty power applications.
• Regulatory compliance: RoHS compliance supports use in regions and products requiring restricted substance adherence.
