LGG2W331MELC30

The LGG2W331MELC30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGG series, engineered for compact, high‑voltage power applications. It combines a 330 µF capacitance with a 450 V rating and a snap‑in radial can package to support high ripple environments while enabling equipment downsizing.

Designed for general‑purpose use where high voltage, elevated temperature endurance and compact footprint matter, the part is offered in tray packing and is in mass production. The LGG family is specified for 105 °C operation and features an ultra‑smaller‑sized case (one rank smaller than LGN) to help reduce board area.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 450 V rated voltage, suitable for high‑voltage filtering and energy storage in power circuits.
• High‑temperature endurance — Rated to operate from −25 °C to 105 °C with a specified life of 2000 hours at 105 °C under DC bias plus rated ripple current.
• Snap‑in radial can package — Snap‑in terminal type (radial, can − snap‑in) allows secure PCB mounting and easy insertion for power supply assemblies; size φ35 × 30 mm provides a compact footprint.
• Ripple current capability — Handles 1.2 A at 120 Hz (low frequency) and 1.716 A at 100 kHz (high frequency) to support smoothing and decoupling in high‑ripple environments.
• Leakage and dissipation — Leakage current specified at 1150 µA; tangent of loss angle (tan δ) max 0.20 at 450 V (measured at 120 Hz, 20 °C), enabling predictable dissipation characteristics.
• Tolerance and stability — Capacitance tolerance ±20% at 120 Hz, 20 °C, with defined impedance ratio and endurance limits per the LGG series specification.
• RoHS compliant & production ready — Conforms to RoHS and is available in tray packing for volume assembly; product status: mass production.

Typical Applications

• Power supply filtering: Bulk and smoothing capacitors in high‑voltage power supplies where 450 V rating and high ripple capability are required.
• Industrial power electronics: Energy storage and decoupling in converters and inverters that operate at elevated temperatures up to 105 °C.
• UPS and backup systems: High‑voltage charge/discharge support where robust leakage and ripple performance are needed.

Unique Advantages

• High‑voltage capability: 450 V rating enables use in higher‑voltage power rails without derating the capacitor selection.
• Compact, space‑saving package: LGG series offers an ultra‑smaller‑sized case (one rank smaller than LGN) in a φ35 × 30 mm snap‑in can to reduce PCB area.
• Robust ripple handling: Specified ripple currents of 1.2 A (120 Hz) and 1.716 A (100 kHz) support both low‑ and high‑frequency ripple environments.
• High‑temperature reliability: Endurance of 2000 hours at 105 °C under rated conditions provides predictable long‑term performance in hot operating environments.
• Defined leakage and dissipation: Leakage current and tan δ specifications allow engineers to model standby losses and thermal behavior accurately.
• Production readiness: RoHS compliance and tray packing with mass production status simplify procurement and assembly for volume designs.
