LLG2W391MELC30

The LLG2W391MELC30 is a Nichicon LLG series aluminum electrolytic capacitor in a snap‑in terminal configuration. It provides 390 µF capacitance at a 450 V rating with polarized construction and is supplied in tray packing for mass production.

Designed as a smaller‑sized member of the LLG family, this capacitor targets general‑purpose equipment where compact, high‑voltage bulk capacitance and reliable endurance at elevated temperature are required.

Key Features

• High voltage rating: 450 V rated voltage suitable for higher‑voltage applications requiring bulk capacitance.
• Capacitance and tolerance: 390 µF nominal with ±20% tolerance (−20% to +20%), specified at 120 Hz, 20°C.
• Snap‑in terminal mounting: Snap‑in (radial can) package for secure board/panel mounting and high‑volume assembly.
• Operating temperature and endurance: Rated for −25°C to +85°C operation with endurance of 2000 hours at 85°C under D.C. bias plus rated ripple current.
• Ripple current capability: Rated ripple current of 2.1 A at 120 Hz and 3.003 A at 100 kHz (specified values).
• Polarized aluminum electrolytic construction: Standard polarized capacitor design for DC bulk and smoothing roles.
• Compact LLG series sizing: Part of the LLG family which is described as a smaller‑sized snap‑in series suitable for equipment downsizing.
• RoHS compliant: Conforms to RoHS (2011/65/EU,(EU)2015/863) requirements.

Typical Applications

• General‑purpose industrial and commercial equipment: Provides bulk capacitance and energy storage where a 390 µF, 450 V polarized capacitor is required.
• Compact power assemblies: LLG series smaller sizing supports equipment downsizing while delivering high‑voltage capacitance in a snap‑in package.
• High‑frequency and ripple environments: Specified ripple current ratings at 120 Hz and 100 kHz make it suitable for designs with defined ripple loads within the stated ratings.

Unique Advantages

• High‑voltage bulk capacitance: 390 µF at 450 V provides substantial stored energy for high‑voltage DC systems.
• Secure snap‑in mounting: Snap‑in terminals enable robust mechanical retention and efficient insertion for production assembly.
• Compact series footprint: Part of the smaller‑sized LLG lineup, helping reduce enclosure and board space compared with larger can types.
• Elevated‑temperature endurance: Endurance specified at 2000 hours at 85°C under rated stress provides predictable life performance for designs operating near the upper temperature limit.
• Measurable ripple handling: Published ripple current ratings at both low and high frequencies allow designers to assess thermal and lifetime effects accurately.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for electronic equipment.
