LGG2W471MELB45

The LGG2W471MELB45 is an aluminum electrolytic capacitor from Nichicon’s LGG series featuring a snap-in terminal, 470 µF capacitance and a 450 V rated voltage. It is designed as an ultra-smaller-sized snap-in can to support equipment downsizing while providing high-voltage bulk capacitance for general-purpose applications.

Key value propositions include a compact φ30×45 mm can (L: 4.5 × D: 3 cm), 105°C endurance rating with defined lifetime data, and RoHS compliance — all intended for reliable performance in higher-voltage, general-purpose circuits.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 450 V rated voltage, suitable where substantial high-voltage bulk capacitance is required.
• High-temperature Endurance — Rated for operation up to 105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Operating Temperature Range — –25°C to +105°C for the 400–450 V range, matching the 450 V rating.
• Snap-in Radial Can Package — Snap-in terminal type in a compact radial can (φ30×45 mm / L: 4.5 × D: 3 cm) for board-mounted bulk capacitance.
• Specified Ripple Current — Rated ripple current of 1.55 A at 120 Hz and 2.216 A at 100 kHz to guide thermal and ripple handling in designs.
• Leakage and Loss Characteristics — Leakage current defined by I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) maximum 0.20 at 450 V (measured at 120 Hz, 20°C).
• Compact Series Design — LGG series is specified as “ultra-smaller-sized” and one rank smaller in case size than LGN, supporting equipment downsizing efforts.
• RoHS Compliant — Conforms to RoHS requirements as indicated in product data.

Typical Applications

• General-purpose power supplies — Provides high-voltage bulk capacitance and smoothing for general-purpose equipment requiring 450 V rated capacitors.
• Equipment downsizing — Compact φ30×45 mm snap-in can supports reduced board footprint and smaller power assemblies.
• High-voltage industrial and commercial circuits — Suited for general-purpose high-voltage filtering and energy storage where 470 µF at 450 V is needed.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage designs without stacking multiple components.
• 105°C lifetime data: Endurance specified at 2000 hours at 105°C gives a measurable reliability figure for thermal-stressed applications.
• Compact snap-in form factor: Ultra-smaller-sized LGG series design and snap-in mounting help save PCB area and simplify mechanical retention.
• Defined ripple performance: Published ripple current values at both 120 Hz and 100 kHz allow accurate thermal and ripple budgeting in power designs.
• Predictable electrical behavior: Leakage current formula and tan δ limits at rated conditions support component selection and margining.
• Regulatory compliance: RoHS compliance supports use in regulated product lines and global shipments.
