LGC2H471MELC45

The LGC2H471MELC45 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGC series optimized for long life and compact installations. It delivers 470 µF at a 500 V rating with polarized snap‑in mounting and is designed for general‑purpose power applications where equipment downsizing and high temperature endurance are required.

Key value propositions include a high 500 V rating, a 105°C operating temperature capability with 5,000 hours endurance at that temperature, and an ultra‑smaller case size—one rank smaller than the LGX series—making it suitable for space‑constrained designs.

Key Features

• Capacitance and Voltage: 470 µF rated capacitance at 500 V for bulk energy storage and smoothing in high‑voltage circuits.
• High‑Temperature Long Life: Rated for –40°C to +105°C with endurance specified as 5000 hours at 105°C under DC bias plus rated ripple current.
• Compact Snap‑In Package: Radial snap‑in can package (size L: 4.5 × D: 3.5 cm) designed for secure PCB mounting and equipment downsizing; one rank smaller case than LGX.
• Rated Ripple Current: Specified ripple current of 2.02 A at 120 Hz and 2.889 A at 50 kHz for handling AC ripple within rated limits.
• Electrical Stability: Capacitance tolerance ±20% at 120 Hz, 20°C; leakage current defined by I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ ≤ 0.25 at 120 Hz, 20°C.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies: Bulk energy storage and smoothing in high‑voltage power supplies up to 500 V where compact size is required.
• General‑Purpose Industrial Equipment: Filtering and decoupling in industrial electronics that require long‑life operation at elevated temperatures.
• Downsized Equipment Designs: Replacement or redesigns targeting reduced enclosure size—benefits from the ultra‑smaller case (one rank smaller than LGX).

Unique Advantages

• High Voltage Capability: 500 V rating enables use in higher‑voltage power rails without series stacking.
• Proven High‑Temperature Endurance: Endurance specified for 5000 hours at 105°C supports reliable operation in thermally demanding environments.
• Space‑Saving Form Factor: Ultra‑smaller case size (one rank smaller than LGX) and 4.5 × 3.5 cm dimensions help reduce PCB real estate and cabinet volume.
• Robust Ripple Handling: Rated ripple currents at 120 Hz and 50 kHz demonstrate capability to manage AC stress across common operating frequencies.
• Clear Electrical Limits: Leakage current and dissipation factor (tan δ ≤ 0.25) are specified for predictable behavior during design and testing.
• Regulatory Compliance: RoHS compliance supports use in regions requiring restricted‑substance adherence.
