LGL2G331MELZ45

The LGL2G331MELZ45 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 330 µF capacitance at a 400 V rating in an ultra-smaller-sized, radial can with snap‑in mounting.

Engineered for elevated-temperature operation, this part offers a wide operating range from –25°C to 105°C, defined endurance of 2000 hours at 105°C, and ripple performance suitable for power supply filtering and smoothing in space‑constrained assemblies.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 400 V, ±20% tolerance, providing a stable energy storage element for high-voltage DC applications.
• Snap‑in Radial Package — Radial, can-type snap‑in package (22 mm × 45 mm) for secure, board-level mounting in assemblies that require snap‑in terminals.
• High‑Temperature Endurance — Rated for operation from –25°C to 105°C with a specified lifetime of 2000 hours at 105°C under rated DC bias plus rated ripple current.
• Low Loss Characteristics — Tanδ (DF) specified at a maximum of 0.15 (at 20°C, 120 Hz) to control dissipation factor in AC conditions.
• Leakage Current — Leakage current approximately 1.08 mA (1080 µA), measured under standard conditions, supporting predictable DC performance.
• Ripple Current Capability — Rated ripple current of 1.07 A at 120 Hz and 1.53 A at higher frequency (50 kHz), enabling effective ripple handling across a broad frequency range.

Typical Applications

• General Purpose — Designed for a broad set of general-purpose power electronics roles that require 400 V rated voltage and substantial bulk capacitance.
• Elevated‑Temperature Environments — Suitable where operation up to 105°C and defined 2000‑hour endurance are required.
• Snap‑in Power Assemblies — Snap‑in terminal configuration simplifies placement and mechanical retention in assemblies that use radial can capacitors.

Unique Advantages

• High voltage capability: 400 V rating supports high‑voltage DC link and filtering requirements without up‑rating multiple lower‑voltage parts.
• Compact high‑temperature design: Ultra‑smaller-sized 22 mm × 45 mm can with 105°C endurance enables dense power assemblies while meeting thermal requirements.
• Predictable ripple performance: Specified ripple currents at 120 Hz (1.07 A) and 50 kHz (1.53 A) allow designers to size capacitors against real operating ripple conditions.
• Controlled dissipation: Low tanδ (max. 0.15 at 120 Hz, 20°C) helps minimize internal heating under AC stress.
• Manufacturer pedigree: Produced by Nichicon as part of the LGL series, providing consistency with series specifications and dimensional references.
