LGN2E331MELA25

The LGN2E331MELA25 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGN series designed for general-purpose power applications. It provides 330 µF capacitance at a 250 V rating in a compact radial can with snap-in mounting and is specified for operation from −40°C to 105°C.

Engineered for reliable performance under elevated temperatures, this part withstands 3000 hours of rated ripple current at 105°C and is RoHS compliant, making it suitable for demanding power supply filtering and energy-storage roles where durability and compact sizing are priorities.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance at a 250 V rated voltage, with tolerance ±20% (120 Hz, 20°C).
• High Temperature Endurance — Designed to meet series endurance: capacitance change within ±20% and leakage/tan δ within specified limits after 3000 hours at 105°C under rated ripple and DC bias.
• Compact Snap-in Package — Radial can, snap-in terminal type with a smaller case size (one rank smaller than LGU) for space-constrained board designs; nominal size L: 2.5 × D: 2.5 cm.
• Wide Operating Range — Specified operating temperature range −40°C to +105°C for reliable operation across common thermal environments.
• Ripple Current Capability — Rated ripple current: 1.2 A at 120 Hz (low frequency) and 1.8 A at 100 kHz (high frequency), supporting load smoothing and decoupling tasks.
• Low Leakage — Meets LGN series leakage specification (I ≤ 3/√C μA after 5 minutes’ application of rated voltage at 20°C).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized Design — Electrolytic, polarized capacitor for DC power applications.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction on DC power rails in general-purpose power supplies and converters.
• Energy Storage for Power Electronics — Local energy reserve for transient loads and decoupling in industrial and commercial power subsystems.
• Control and Drive Circuits — Filtering and stabilization in motor control, inverter, and drive electronics where elevated temperature endurance is required.

Unique Advantages

• Compact footprint: One rank smaller case than LGU-series parts, enabling denser board layouts without sacrificing capacitance.
• High-temperature reliability: Endurance specified for 3000 hours at 105°C under rated ripple current provides predictable aging and performance in hot environments.
• Dual-frequency ripple performance: Rated ripple current data at both 120 Hz and 100 kHz supports design validation across low- and high-frequency power systems.
• Industry-standard mounting: Snap-in radial can simplifies PCB assembly for high-current, high-reliability power modules.
• Regulatory-ready: RoHS compliance ensures deployment in regions and products requiring restricted-substance conformance.
