LLG2G391MELA40

The LLG2G391MELA40 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LLG series. It delivers 390 µF of capacitance at a 400 V rating in a smaller case format, designed to support equipment downsizing.

Intended for general‑purpose use, the part combines high-voltage bulk capacitance, snap‑in mounting, and RoHS compliance for reliable integration into a range of electronic systems.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance rated at 400 V provides substantial bulk energy storage for high-voltage circuits.
• Snap‑in Package — Radial can with snap‑in terminals for secure through‑hole mounting and robust board retention.
• Compact Case for Downsizing — One rank smaller case size than the LLS series, supporting space‑constrained designs; physical size L: 4 × D: 2.5 cm.
• Operating Temperature & Endurance — Rated for −25 °C to +85 °C with a 2000‑hour endurance at 85 °C under rated conditions.
• Ripple Current Ratings — 1.9 A at 120 Hz (low frequency) and 2.717 A at 100 kHz (high frequency) to support AC ripple handling in power circuits.
• Polarized, General Purpose — Polarized electrolytic construction for general‑purpose power applications.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Equipment — Provides high‑voltage bulk capacitance in equipment where a smaller case size helps reduce overall system footprint.
• Power Supply Energy Storage — Suited for DC link/bulk storage and smoothing roles in high‑voltage power circuits thanks to 390 µF at 400 V.
• Industrial Electronics — Designed for applications requiring rated endurance at elevated temperature (2000 h at 85 °C) and reliable snap‑in mounting.

Unique Advantages

• High‑Voltage Bulk in a Compact Package: 390 µF at 400 V delivered in a one‑rank smaller case enables downsized high‑voltage designs.
• Robust Ripple Handling: Specified ripple currents at both 120 Hz and 100 kHz support a range of AC conditions encountered in power circuitry.
• Durability at Elevated Temperature: 2000 hours of endurance at 85 °C provides predictable life performance for long‑running equipment.
• Secure Through‑Hole Mounting: Snap‑in terminals simplify mechanical retention and board assembly for heavier can‑style capacitors.
• Regulatory Compliance: RoHS conformity supports designs requiring restricted‑substance compliance.
