LGG2G471MELA50

The LGG2G471MELA50 is a snap-in terminal type aluminum electrolytic capacitor designed for general-purpose applications requiring high voltage and compact sizing. It delivers 470 µF at a 400 V rating with a -25°C to 105°C operating range and a 2000 h endurance at 105°C.

Part of Nichicon’s LGG series, this component targets designs where smaller case size and reliable high-voltage bulk capacitance are required—suited for equipment downsizing while remaining RoHS compliant and available in mass production.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 400 V provides substantial bulk energy storage for high-voltage circuits.
• Snap-in Mounting — Snap-in terminal (radial, can - snap-in) for secure panel or chassis installation and straightforward assembly in power subsystems.
• High Endurance — 2000 hours life at 105°C under rated conditions, with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Low Loss (tan δ) — 0.15 maximum tan δ (DF) at 20°C, 120 Hz, supporting stable AC performance under rated conditions.
• Ripple Current Capability — 1550 mA at 120 Hz (low frequency) and 2216.5 mA at 100 kHz (high frequency), enabling handling of significant AC ripple in power applications.
• Leakage Current — Specified leakage current of 1300 µA (I ≤ 3√CV formula applies in datasheet) after rated-voltage application, aiding predictable design margins.
• Compact Dimensions — Size φ25 × 50 mm supports equipment downsizing; LGG series is marketed as “Ultra-Smaller-Sized” with one rank smaller case than LGN.
• Polarized Aluminum Electrolyte — Polarized construction for DC bulk filtering and smoothing in power circuits.
• Packaging & Production — Tray packing and mass production status for predictable procurement and board-level handling.
• Regulatory — RoHS compliant as stated in product data.

Typical Applications

• General-purpose power systems — Provides high-voltage bulk capacitance for DC link, filtering, and energy storage in general-purpose power electronics.
• Equipment downsizing projects — Compact φ25 × 50 mm snap-in package helps reduce board footprint while maintaining 400 V capability.
• High-voltage assemblies — Suited for assemblies that require polarized aluminum electrolytic bulk capacitors with defined ripple and leakage specifications.

Unique Advantages

• High-voltage bulk capacitance: 470 µF at 400 V supports applications needing substantial energy storage at elevated voltages.
• Compact, snap-in form factor: Ultra-smaller-sized LGG series case (one rank smaller than LGN) enables more compact power module layouts.
• Clear endurance specification: 2000 h at 105°C with post-test limits for capacitance, tan δ, and leakage current provides predictable long-term behavior.
• Measured ripple performance: Specified ripple currents at both 120 Hz and 100 kHz let designers size thermal and ripple-handling margins accurately.
• Controlled dielectric loss: Low tan δ (0.15 max at 20°C, 120 Hz) helps maintain efficient AC performance in filtering applications.
• Production-ready packaging: Tray packing and mass production status support volume manufacturing and supply planning.
