LLG2W391MELB35

The LLG2W391MELB35 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LLG series. It delivers 390 µF capacitance at a 450 V rated voltage in a compact radial, can-type snap-in package designed for equipment downsizing.

Engineered for general-purpose applications, the part offers a -25 °C to 85 °C operating range, RoHS compliance, and a rated endurance of 2000 hours at 85 °C under DC bias plus rated ripple current.

Key Features

• Capacitance and Tolerance — 390 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C.
• High Voltage Rating — Rated for 450 V operation suitable for high-voltage, general-purpose applications requiring polarized capacitance.
• Snap-In Radial Package — Snap-in terminal type in a radial can package for secure, board-mounted installations and simplified assembly.
• Compact Case for Downsizing — One rank smaller case size than the LLS series, intended to support equipment miniaturization efforts.
• Operating Temperature and Endurance — Specified for -25 °C to 85 °C with an endurance rating of 2000 hours at 85 °C under rated conditions.
• Ripple Current Performance — Rated ripple current of 2.1 A at 120 Hz and 3.003 A at 100 kHz for handling AC ripple under load.
• Leakage and Loss Characteristics — Manufactured to meet Nichicon’s leakage current and tan δ limits for the LLG series (specifications measured after standard test conditions).
• RoHS Compliance — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power circuits — Use where a polarized 390 µF, 450 V snap-in capacitor is required for bulk capacitance in board-mounted designs.
• Compact high-voltage assemblies — Sized to enable equipment downsizing by offering a smaller case footprint than comparable LLS parts.
• Industrial power modules — Suitable for assemblies requiring robust ripple handling and 2000-hour endurance at 85 °C.

Unique Advantages

• Smaller case footprint: One rank smaller case than LLS supports tighter packaging and reduced board space.
• High-voltage capability: 450 V rating provides headroom for higher-voltage general-purpose designs.
• Proven endurance: 2000 hours at 85 °C under rated conditions ensures predictable lifetime performance for medium-term deployments.
• Practical ripple handling: Specified ripple currents at 120 Hz and 100 kHz help manage AC stress in power applications.
• Assembly-friendly termination: Snap-in radial can design simplifies mounting and secures the component on the PCB.
• Regulatory compliance: RoHS conformity supports environmentally constrained designs and procurement requirements.
