LLG2G331MELA35

The LLG2G331MELA35 is a Nichicon LLG series aluminum electrolytic capacitor: a 330 µF, 400 V, snap-in terminal, radial can designed for general-purpose applications. It delivers high-voltage bulk capacitance in a compact, snap-in package and is RoHS compliant (2011/65/EU, (EU)2015/863).

Targeted at designs where equipment downsizing and reliable power handling are important, the LLG2G331MELA35 combines specified ripple current capability and endurance performance for stable operation in demanding environments.

Key Features

• Capacitance & Voltage  330 µF nominal capacitance with a 400 V rated voltage and ±20% capacitance tolerance (measured at 120 Hz, 20°C).
• Compact Snap-in Package  Radial, snap-in terminal construction in the LLG series; one rank smaller case size than LLS to support equipment downsizing and secure PCB mounting.
• Temperature Range & Endurance  Rated for operation from –25°C to +85°C with an endurance specification of 2000 hours at 85°C under DC bias plus rated ripple current (capacitance change within ±20%, tan δ ≤ 200% of initial spec, leakage current ≤ initial specified value).
• Ripple Current Capability  Specified ripple current of 1.7 A at 120 Hz and 2.431 A at 100 kHz, supporting AC ripple handling in power circuits.
• Electrical Loss and Low-Temperature Behavior  Maximum tan δ of 0.15 for 160–400 V (measured at 120 Hz, 20°C). Impedance stability at low temperature: Z(–25°C)/Z(+20°C) up to 8 for the 400 V rating (measured at 120 Hz).
• Leakage Current and Reliability  Initial leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20°C; shelf-life and endurance limits defined to preserve performance after high-temperature storage and application of voltage treatment.
• Regulatory Compliance  RoHS compliant to 2011/65/EU and (EU)2015/863.

Typical Applications

• General-Purpose Power Circuits  Suitable for applications requiring 330 µF at 400 V in a snap-in form factor for bulk capacitance and filtering.
• Equipment Downsizing  Compact case size (one rank smaller than LLS) for designs that require reduced board space without sacrificing voltage rating.
• Power Modules and Subassemblies  Fits into power subassemblies where specified ripple current handling and endurance at 85°C are required.

Unique Advantages

• High-voltage bulk capacitance in a compact form: 330 µF at 400 V delivers substantial energy storage while using a smaller case than comparable LLS parts.
• Snap-in mounting for secure assembly: Radial snap-in terminals enable reliable mechanical retention and straightforward PCB installation.
• Defined ripple performance: Rated ripple currents at both 120 Hz and 100 kHz provide clear guidance for thermal and electrical design.
• Endurance and predictable aging: 2000 hours at 85°C endurance specification with measurable limits on capacitance change, tan δ, and leakage current supports lifetime planning.
• Low-temperature impedance characterization: Documented impedance ratio at –25°C helps designers account for performance across the specified temperature range.
• Regulatory clarity: RoHS compliance to current directives supports regulatory requirements for many electronic products.
