LGG2G391MELC30

The LGG2G391MELC30 is a snap-in terminal type aluminum electrolytic capacitor from Nichicon’s LGG series. It provides 390 µF capacitance at a 400 V rating in an ultra-smaller-sized snap-in can designed for general-purpose applications.

Engineered for compact power designs, this component combines a high voltage rating with defined ripple-current capability and long-term endurance, making it suitable for applications that require stable DC bulk capacitance in a snap-in package.

Key Features

• Capacitance & Voltage: 390 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Snap-in Package & Compact Size: Snap-in radial can package in a φ35 × 30 mm (D × L) form factor; LGG series is specified as an ultra-smaller-sized option for equipment downsizing.
• Ripple Current Performance: Low-frequency ripple current 1.55 A at 120 Hz and high-frequency ripple current 2.216 A at 100 kHz, enabling handling of AC ripple in powered systems.
• Thermal Range & Endurance: Rated operating temperature −25°C to +105°C with 2000 hours endurance at 105°C under DC bias plus rated ripple current as specified.
• Electrical Loss & Leakage: Tangent of loss angle (tan δ) max 0.15 (measured at 20°C, 120 Hz) and specified leakage current of 1,180 µA.
• Polarized, Tray Packaging & Production Status: Polarized snap-in termination, supplied in tray packing and listed as mass production; RoHS compliant.

Typical Applications

• General-purpose power circuits: Provides DC bulk capacitance and ripple smoothing where a 390 µF, 400 V snap-in electrolytic capacitor is required for general-purpose use.
• Industrial power modules: Used in equipment that benefits from a compact, high-voltage snap-in capacitor with defined ripple-current and endurance characteristics.
• Power supply filtering: Suited to general-purpose filtering roles requiring a polarized aluminum electrolytic in a snap-in can format.

Unique Advantages

• Compact, space-saving package: LGG series offers an ultra-smaller-sized case (one rank smaller than LGN), enabling equipment downsizing while maintaining 400 V capability.
• Defined ripple handling: Specified low- and high-frequency ripple currents (1.55 A @ 120 Hz, 2.216 A @ 100 kHz) provide clear design parameters for thermal and ripple management.
• High-temperature endurance: Rated for 2000 hours at 105°C under DC bias plus ripple current, supporting long-term performance in hotter operating environments.
• Measurable electrical characteristics: tan δ specified at 0.15 (20°C, 120 Hz) and a specified leakage current of 1,180 µA for predictable circuit behavior.
• Manufacturing-friendly packaging: Tray packing supports automated assembly and handling for production environments.
• Regulatory compliance: RoHS compliant as part of the LGG series specifications.
