LGW2G331MELA50

The LGW2G331MELA50 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGW series. It provides 330 µF capacitance at a 400 V rating and is designed for general-purpose applications that require high ripple current handling at elevated temperatures.

Engineered for sustained operation at up to 105°C, this polarized, radial can (snap‑in) capacitor delivers extended endurance under rated ripple current conditions and is RoHS compliant.

Key Features

• High Voltage / Capacitance — 330 µF rated at 400 V, suitable where substantial energy storage and voltage handling are required.
• Snap‑In Terminal Package — Radial, can‑style snap‑in mounting for secure PCB installation and straightforward assembly.
• 105°C Operating Temperature — Rated for operation up to 105°C, supporting designs exposed to elevated ambient temperatures.
• High Ripple Current Endurance — Withstands 3000 hours of application of rated ripple current at 105°C, providing long‑term stability under continuous ripple stress.
• Measured Ripple Current — Specified ripple current performance: 2.12 A at 120 Hz and 3.032 A at 50 kHz, enabling reliable AC ripple handling across frequency ranges.
• Polarized Electrolytic — Polarized design for DC filtering and energy‑storage roles; follow polarity marking during assembly.
• Leakage Current Specification — Meets leakage current criterion I ≤ 3√CV (µA) after 5 minutes application of rated voltage at 20°C, per datasheet guidance.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Size: L: 5 × D: 2.5 cm (radial can), balancing capacitance with a compact board area for snap‑in mounting.

Typical Applications

• General‑purpose power filtering — Use where 400 V, 330 µF capacitance and robust ripple handling at up to 105°C are required for smoothing and decoupling.
• Industrial power electronics — Suitable for circuits needing durable electrolytic energy storage and sustained ripple endurance under elevated temperatures.
• AC/DC conversion and DC link — Polarized, high‑voltage capacitance supports energy buffering and ripple absorption in power conversion stages.

Unique Advantages

• Long ripple‑endurance: Designed to withstand 3000 hours of rated ripple current at 105°C, reducing the need for early replacement in high‑stress installations.
• Broad frequency ripple capability: Rated ripple current values at both 120 Hz and 50 kHz demonstrate usable performance across low and high ripple frequencies.
• High temperature rating: 105°C operating temperature supports deployments in hotter environments while maintaining specified performance.
• Practical snap‑in mounting: Radial snap‑in package simplifies PCB retention and mechanical stability for power modules and assemblies.
• Standards‑based leakage behavior: Leakage current follows the datasheet formula I ≤ 3√CV (µA), providing predictable behavior after voltage application.
• Regulatory compliance: RoHS compliance supports use in regions and products requiring restricted substance adherence.
