LLG2W151MELA25

The LLG2W151MELA25 is a Nichicon LLG-series aluminum electrolytic capacitor in a snap-in terminal, smaller-sized radial can. It provides 150 µF capacitance at a 450 V rating for general-purpose electronic equipment where a compact, high-voltage capacitor is required.

Designed one rank smaller in case size than the LLS series and compliant with the RoHS directive, this part is suited for equipment downsizing while delivering defined endurance and temperature performance.

Key Features

• Electrical Performance — 150 µF nominal capacitance with a rated voltage of 450 V and capacitance tolerance of ±20% (at 120 Hz, 20°C).
• Ripple Current — Specified ripple handling of 1.04 A at 120 Hz and 1.487 A at 100 kHz, supporting AC ripple imposed by power circuits within the stated ratings.
• Temperature Range & Endurance — Operates from −25°C to +85°C with an endurance rating of 2000 hours at 85°C under rated D.C. bias plus rated ripple current.
• Package & Mounting — Snap-in radial can (snap-in terminal type) with compact footprint, dimension L: 2.5 × D: 2.5 cm, optimized for secure PCB mounting and reduced case size compared to the LLS series.
• Polarized — Polarized aluminum electrolytic construction for DC applications.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power circuits — Use where 150 µF at 450 V is required for DC-link smoothing or filtering in space-constrained designs.
• Compact electronic equipment — Suited to designs targeting reduced enclosure size thanks to a case one rank smaller than the LLS series.
• Board-mounted power modules — Snap-in terminal provides a robust mounting option for radial can installations on PCBs.

Unique Advantages

• Compact high-voltage solution: Delivers 150 µF at 450 V in a smaller case size, enabling reduced footprint in systems that require high-voltage capacitance.
• Defined ripple capability: Published ripple current values at 120 Hz and 100 kHz make it easier to match the capacitor to expected circuit ripple conditions.
• Endurance under rated conditions: 2000 hours at 85°C with DC bias and rated ripple provides a measurable reliability target for thermal and electrical stress.
• Secure snap-in mounting: Radial snap-in terminals offer reliable board retention for vertical can installations.
• RoHS compliance: Conforms to RoHS directives, supporting regulatory requirements for electronic equipment.
