LGN2G331MELB35

The LGN2G331MELB35 is a 330 µF, 400 V polarized aluminum electrolytic capacitor in a snap‑in radial can designed for general‑purpose power filtering and smoothing. It is a smaller‑sized, high‑temperature snap‑in solution engineered to withstand sustained ripple current at elevated temperature.

Key attributes include a 105°C operating rating with verified endurance under rated ripple current for 3000 hours, a compact footprint one rank smaller than the LGU series, and RoHS compliance for environmental requirements.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance at a 400 V rated voltage, with ±20% tolerance.
• High‑temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C, meeting the LGN series endurance criteria.
• Ripple Current Capability — Rated ripple current specified as 1.44 A at 120 Hz and 2.059 A at 100 kHz, suitable for sustained ripple handling in power circuits.
• Snap‑in Radial Can Package — Snap‑in mounting for secure panel/board installation; package described as radial, can — snap‑in.
• Compact Size — One rank smaller case than the LGU series; listed size dimensions L: 3.5 × D: 3 cm with a seated height max of 1.378 inch.
• Operating Range and Polarization — Polarized capacitor rated for operation from −25°C to +105°C.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Smoothing and bulk capacitance in power supply stages where 400 V rating and high ripple endurance are required.
• High‑temperature power environments — Circuits that demand sustained performance up to 105°C with long endurance at rated ripple current.
• Snap‑in mounting assemblies — Designs that prefer snap‑in radial cans for robust board or chassis installation and simplified assembly.

Unique Advantages

• Endurance at elevated temperature: Rated for 3000 hours at 105°C under rated ripple current, supporting longer service life in hot operating conditions.
• High voltage capability: 400 V rating enables use in higher‑voltage power stages without additional series stacking.
• Proven ripple handling: Specified ripple currents at both 120 Hz and 100 kHz provide quantified performance for designers balancing low‑ and high‑frequency ripple.
• Space‑efficient packaging: One rank smaller than the LGU series and compact dimensions (L: 3.5 × D: 3 cm) for tighter power module layouts.
• RoHS compliant: Meets current RoHS directive requirements, simplifying environmental compliance for assemblies.
• Clear electrical tolerances: ±20% capacitance tolerance and defined leakage and tan δ limits as per LGN series specifications for predictable circuit behavior.
