LGG2G331MELC25

The LGG2G331MELC25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGG series, delivering 330 µF capacitance at a 400 V rating. Designed for compact assemblies, this part targets general-purpose power applications that require high-voltage bulk capacitance with robust ripple handling and elevated temperature endurance.

Key value propositions include a compact φ35 × 25 mm case, snap-in mounting for secure PCB retention, and proven endurance of 2000 hours at 105°C—making it suitable where space, longevity, and stable electrical performance under stress are essential.

Key Features

• Electrical Characteristics – 330 µF nominal capacitance with ±20% tolerance and a 400 V rated voltage for high-voltage bulk energy storage.
• Loss and Leakage – Tangent of loss angle (tan δ) up to 0.15 (measured at 20°C, 120 Hz) and a specified leakage current of 1080 µA, offering predictable electrical behavior for power designs.
• High Ripple Capability – Low-frequency ripple current of 1.15 A (120 Hz) and high-frequency ripple current of 1.645 A (100 kHz) to support sustained ripple stresses in power conversion circuits.
• Thermal and Endurance Performance – Rated for operation from −25°C to 105°C with an endurance rating of 2000 hours at 105°C under DC bias plus rated ripple current.
• Compact Snap‑in Package – Radial, can-type snap-in construction (φ35 × 25 mm) for secure mounting and space-efficient layout; tray packing for production handling.
• Compliance and Production – RoHS compliant and listed as mass production status, supporting volume deployment and regulatory needs.

Typical Applications

• General-purpose power filtering – Bulk capacitance and 400 V rating for smoothing and energy storage in power conversion and high-voltage power rails.
• Industrial power supplies – Handles sustained ripple current and elevated operating temperature (−25°C to 105°C) for robust long-term operation.
• Compact equipment designs – φ35 × 25 mm case offers a smaller footprint suitable for equipment down‑sizing where space savings are required.

Unique Advantages

• Compact high-voltage capability: 330 µF at 400 V in a φ35 × 25 mm package reduces board area for high-voltage bulk capacitance.
• Strong ripple handling: Rated ripple currents of 1.15 A (120 Hz) and 1.645 A (100 kHz) support designs with significant AC stress without frequent replacement.
• Elevated temperature endurance: 2000 hours at 105°C under rated conditions provides predictable life for high-temperature environments.
• Predictable electrical performance: Specified tan δ (0.15 at 20°C, 120 Hz) and leakage current figures enable reliable design margining and simulation.
• Secure, production-friendly packaging: Snap-in radial can and tray packing simplify assembly and support volume manufacturing workflows.
• Regulatory readiness: RoHS compliance supports deployment in regions and products requiring restricted-substance adherence.
