LGGW6471MELB45

The LGGW6471MELB45 is a snap-in, aluminum electrolytic capacitor from Nichicon's LGG series, offering 470 µF capacitance at a 420 V rating in a compact φ30 × 45 mm can. Designed for general-purpose use, it targets equipment where high-voltage bulk capacitance, compact size and robust thermal endurance are required.

This part combines snap-in mounting for secure chassis or PCB assemblies with industry-oriented electrical characteristics—notably a wide operating temperature range appropriate for the 400–450 V category and long-term endurance at elevated temperatures.

Key Features

• Capacitance and Voltage: 470 µF rated at 420 V for high-voltage bulk energy storage and smoothing.
• Snap-in Radial Can Package: Snap-in terminal type and radial can package provide reliable mechanical retention and fast assembly for high-current applications.
• Compact Dimensions: φ30 × 45 mm (L: 4.5 × D: 3.0 cm) case size—part of the LGG series designed one rank smaller than the LGN series to support equipment downsizing.
• Temperature Range and Endurance: Rated for use from –25°C to +105°C (400–450 V category) with endurance specified as 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability: Rated ripple current of 1.86 A at 120 Hz (low frequency) and 2.66 A at 100 kHz (high frequency) to support real-world ripple conditions.
• Electrical Stability: Capacitance tolerance ±20% at 120 Hz/20°C; leakage current limited by I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ max 0.15 for the 160–420 V range.
• RoHS Compliant: Meets RoHS directive requirements.

Typical Applications

• Industrial Power Supplies: Provides bulk filtering and energy storage where 420 V DC-link and snap-in mounting are needed.
• Power Conversion Equipment: Suitable for mains-side smoothing and DC-link use in general-purpose converters and inverters.
• Commercial and Industrial Electronics: Fits compact assemblies that require a high-voltage electrolytic capacitor with proven endurance at elevated temperatures.

Unique Advantages

• High-voltage bulk capacitance: 470 µF at 420 V supplies substantial energy storage for high-voltage circuits without increasing part count.
• Space-saving LGG form factor: One rank smaller than LGN-series cases, enabling equipment downsizing while retaining required capacitance.
• Designed for elevated-temperature operation: Endurance rated 2000 hours at 105°C under DC bias plus ripple current supports long-term reliability in hot operating environments.
• Robust ripple handling: Specified ripple currents at both 120 Hz and 100 kHz allow designers to assess performance across common frequency ranges.
• Clear electrical limits and stability: Defined leakage current formula, tan δ and impedance stability at low temperature provide measurable parameters for system-level design.
• Regulatory compliance: RoHS compliant for use in environments requiring restricted substance adherence.
