LGY1J472MELB40

The LGY1J472MELB40 is a snap‑in terminal aluminum electrolytic capacitor in Nichicon’s LGY series designed for long‑life industrial applications. It delivers 4.7 mF (4700 µF) capacitance at a 63 V rating in a compact φ30 × 40 mm can with snap‑in mounting and tray packing.

Engineered for general purpose power filtering and industrial power supplies—including ballast applications—this part emphasizes dependable ripple handling and extended endurance, supporting target environments from ‑40°C to 105°C.

Key Features

• Capacitance and Voltage — 4.7 mF (4700 µF) nominal capacitance with a rated voltage of 63 V and a capacitance tolerance of ±20%.
• Long Life Endurance — Rated for 5000 hours at 105°C with performance requirements defined for capacitance change, tangent of loss angle (tan δ), and leakage current after endurance testing.
• High Ripple Current Capability — Low frequency ripple current 2.6 A at 120 Hz and high frequency ripple current 2.99 A at 50 kHz, supporting demanding AC ripple environments.
• Controlled Dissipation Factor — tan δ specified at 0.25 (measurement condition: 20°C, 120 Hz) for the 63 V rating, enabling predictable AC loss behavior.
• Robust Temperature Range — Operating from ‑40°C to 105°C for reliable performance across wide ambient conditions.
• Mounting and Packaging — Snap‑in radial can package (φ30 × 40 mm) supplied in tray packing for straightforward assembly and inventory handling.
• Leakage Current — Specified leakage current of 1630 µA (after standard voltage application conditions).
• RoHS Compliant — Conforms to RoHS directive requirements as noted in the product series documentation.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in high‑reliability power modules where long endurance at elevated temperatures is required.
• Ballast Applications — Designed for use in ballast circuits as indicated in the LGY series documentation, providing stable filtering under continuous ripple stress.
• General Purpose Power Filtering — Capacitor for DC link, bulk filtering and decoupling in general purpose designs that require substantial capacitance and ripple handling.

Unique Advantages

• Extended High‑Temperature Endurance: 5000 hours at 105°C provides predictable aging behavior and longer service intervals in hot operating environments.
• High Ripple Handling: Rated ripple currents of 2.6 A (120 Hz) and 2.99 A (50 kHz) reduce heating and stress in high‑ripple circuits, improving reliability under load.
• Compact High‑Capacitance Form Factor: 4700 µF in a φ30 × 40 mm snap‑in can enables high energy density in a small footprint for power assemblies.
• Predictable AC Loss: tan δ specified at 0.25 (20°C, 120 Hz) for the 63 V variant supports design margining for dissipation and thermal management.
• Wide Operating Temperature Range: ‑40°C to 105°C supports deployment across varied ambient conditions without derating outside documented limits.
• Production Ready: Product is listed as mass production and supplied in tray packing for volume manufacturing workflows.
