LGN2V331MELA40

The LGN2V331MELA40 is a Nichicon LGN series aluminum electrolytic capacitor in a snap‑in terminal, smaller‑sized can. It provides 330 µF capacitance at a 350 V rating and is designed for general purpose power applications that require high operating temperature capability and sustained ripple handling.

Engineered for demanding thermal environments, this part supports continuous operation up to 105°C and is manufactured to withstand 3000 hours of rated ripple current at 105°C, offering predictable performance for industrial and power electronic designs.

Key Features

• Capacitance & Voltage — 330 µF capacitance with a 350 V rated voltage suitable for higher‑voltage DC bus and power supply applications.
• High Temperature Endurance — Rated for operation to 105°C and specified to withstand 3000 hours of D.C. bias plus rated ripple current at 105°C.
• Ripple Current Capability — Rated ripple currents of 1.2 A at 120 Hz and 1.716 A at 100 kHz, supporting steady AC ripple handling across common power frequencies.
• Smaller Snap‑In Package — Snap‑in radial can package (L: 4 × D: 2.5 cm) that is one rank smaller in case size than the LGU series, conserving chassis space while delivering robust performance.
• Wide Operating Range — Polarized capacitor with an operating temperature range of −25°C to +105°C (for the 350 V rating), aligning with the LGN series temperature specifications.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Power conversion / DC bus smoothing — Provides bulk capacitance and ripple absorption on 350 V rails for power supplies and converters.
• Industrial power electronics — Designed for use where sustained ripple handling and high temperature endurance are required, such as in motor drive and control power stages.
• Pulse and energy buffering — 330 µF capacitance with rated ripple capability supports transient load buffering and energy smoothing in general purpose power systems.

Unique Advantages

• Proven thermal endurance — Specified to endure 3000 hours at 105°C with D.C. bias plus rated ripple current, enabling predictable long‑term performance in hot operating environments.
• High voltage capability — 350 V rating allows deployment on higher‑voltage DC rails without series stacking.
• Measured high‑frequency ripple performance — Defined ripple current values at both 120 Hz (1.2 A) and 100 kHz (1.716 A) to help designers evaluate AC loss and thermal stress across frequencies.
• Space‑efficient snap‑in form factor — Smaller case size than LGU series offers a compact footprint while retaining snap‑in mechanical robustness for chassis mounting.
• Regulatory readiness — RoHS compliance supports use in assemblies that require restricted‑substance conformance.
