LGG2W331MELA50

The LGG2W331MELA50 is a radial, snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGG series. It delivers 330 µF at a 450 V rating in an ultra‑smaller case size tailored for equipment downsizing while maintaining high ripple capability and long endurance.

Designed for general‑purpose applications, this part combines high voltage handling with compact dimensions (φ25 × 50 mm / L: 5 × D: 2.5 cm), RoHS compliance, and 2,000‑hour endurance at 105 °C for reliable performance in dense power assemblies.

Key Features

• Capacitance & Voltage: 330 µF rated at 450 V for high‑voltage storage and filtering in compact designs.
• Snap‑in Radial Package: Snap‑in terminal, radial can package (φ25 × 50 mm) for secure chassis mounting and straightforward board assembly.
• High Ripple Handling: 1,200 mA rated ripple at 120 Hz (low frequency) and 1,716 mA at 100 kHz (high frequency) to support demanding AC and switching environments.
• Loss Tangent / Stability: tan δ ≤ 0.20 at 20 °C and 120 Hz (450 V rating), providing predictable dissipation characteristics under rated conditions.
• Leakage Current: Specified leakage current of 1,150 µA after voltage application, enabling designers to budget standby and leakage power accurately.
• Temperature & Endurance: Rated for operation from −25 °C to +105 °C with 2,000 hours endurance at 105 °C under rated voltage plus ripple current.
• Compact Series Design: LGG series offers an ultra‑smaller case size (one rank smaller than LGN), helping reduce system footprint.
• Environmental Compliance: RoHS‑compliant construction for modern regulatory requirements.
• Packaging: Supplied in tray packing for mass production handling and assembly.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage in general‑purpose power supplies where a 450 V rating and 330 µF capacitance are required.
• DC Link and Converter Circuits — DC link filtering for converters and inverters that benefit from high ripple handling (1,200 mA @120 Hz, 1,716 mA @100 kHz) and compact footprint.
• Commercial Equipment — General‑purpose power filtering in commercial systems that require long endurance at elevated temperatures (2,000 h at 105 °C) and RoHS compliance.

Unique Advantages

• Compact high‑voltage solution: 330 µF at 450 V in a φ25 × 50 mm can reduces board area versus larger packages, enabling equipment downsizing.
• High ripple capability: Dual ripple ratings for low and high frequency let designers manage both mains ripple and switching ripple with a single capacitor choice.
• Predictable dissipation: Specified tan δ (≤ 0.20 at 20 °C, 120 Hz) and defined leakage current provide reliable thermal and leakage budgeting in system designs.
• Robust thermal endurance: 2,000 hours at 105 °C under rated conditions supports long service life in elevated‑temperature applications.
• Manufacturing ready: Tray packing and mass production status simplify procurement and high‑volume assembly workflows.
• Regulatory readiness: RoHS compliance supports deployment in regions and products that require restricted substance conformance.
