LGN2G331MELA45

The LGN2G331MELA45 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGN series, designed for general purpose applications that require high-voltage, high-temperature performance. This smaller-sized snap-in can delivers 330 µF at 400 V with polarized construction and radial can packaging.

Engineered for sustained operation at elevated temperatures, the part is rated for operation up to 105°C and is specified to withstand 3000 hours of rated ripple-current application at 105°C. The product is RoHS compliant.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance at a rated voltage of 400 V, with a tolerance of ±20% (–20% ~ 20%).
• High-temperature endurance: Endurance specified for 3000 hours at 105°C under D.C. bias plus rated ripple current, with capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial value after the test.
• Snap-in radial can package: Snap-in terminal type, radial can (snap-in) mounting for robust board retention and straightforward installation.
• Ripple current capability: Rated ripple current of 1.44 A at 120 Hz (low frequency) and 2.059 A at 100 kHz (high frequency), supporting sustained AC stress in powered circuits.
• Operating temperature and stability: Specified operating range of –25°C to +105°C for the 400 V rating; low-temperature impedance behavior is characterized in the datasheet.
• Leakage and loss characteristics: Leakage current rating defined as I ≤ 3/√(µA) after 5 minutes’ application of rated voltage at 20°C; tan δ (loss tangent) max. 0.15 for rated voltages up to 420 V (measured at 120 Hz, 20°C).
• Compact footprint: Smaller-sized case (one rank smaller than LGU) with dimensions approximately L: 4.5 × D: 2.5 cm for space-constrained designs.
• Regulatory status: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power modules: Suitable where a 400 V, 330 µF snap-in electrolytic capacitor is needed for general-purpose power circuitry.
• High-temperature assemblies: Applicable in equipment requiring sustained performance at up to 105°C with specified ripple-current endurance.
• Panel or chassis-mounted power equipment: Snap-in terminal configuration provides secure mechanical mounting for radial-can installations in general-purpose systems.

Unique Advantages

• Long high-temperature endurance: Specified to withstand 3000 hours of rated ripple current at 105°C, supporting durable operation under thermal stress.
• High-voltage capability: 400 V rated voltage allows use in higher-voltage general-purpose circuits where increased DC blocking and energy storage are required.
• Measured ripple performance: Explicit low- and high-frequency ripple current ratings (1.44 A at 120 Hz; 2.059 A at 100 kHz) help predict thermal and electrical behavior under AC loading.
• Smaller case size: One rank smaller than LGU and compact physical dimensions (L: 4.5 × D: 2.5 cm) reduce board area for space-constrained designs.
• Clear electrical characterization: Leakage current and tan δ specifications (I ≤ 3/√µA after 5 minutes; tan δ max. 0.15 at relevant voltages) enable predictable selection and margining.
• RoHS compliance: Meets restricted substance requirements for regulated markets and assemblies.
