LGU1J472MELA

The LGU1J472MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, offering 4700 µF capacitance at a 63 V rating. It is a polarized, radial can (snap‑in) component designed for general‑purpose power applications that require high capacitance, elevated temperature endurance and robust ripple handling.

Engineered for continuous operation up to 105°C with a 3000‑hour endurance rating, this part is suited to designs where sustained ripple current and long life under thermal stress are important—while maintaining RoHS compliance and tray packing for production workflows.

Key Features

• Capacitance & Tolerance — 4700 µF (4.7 mF) with a tolerance of −20% to +20% at 20°C, 120 Hz, providing substantial bulk capacitance for energy smoothing and decoupling.
• Voltage Rating — Rated for 63 V operation, suitable for mid‑voltage power rails and storage applications requiring this voltage headroom.
• High Temperature Endurance — Rated life of 3000 hours at 105°C when subjected to D.C. bias plus rated ripple current, supporting extended operation in elevated ambient conditions.
• Ripple Current Capability — Low‑frequency ripple current of 2.97 A (120 Hz) and high‑frequency ripple current of 3.416 A (50 kHz), enabling effective handling of both mains‑related and switching noise.
• Loss and Leakage Characteristics — Loss tangent (tan δ) of 0.25 measured at 20°C, 120 Hz, and specified leakage current of 1630 µA after voltage application, allowing designers to size for dissipation and standby leakage.
• Thermal Range — Operating temperature −40°C to +105°C to cover a broad set of industrial and commercial environments.
• Package & Mounting — Snap‑in radial can (φ25 × 50L, nominal L: 5 × D: 2.5 cm) for secure PCB mounting and efficient assembly; supplied in tray packing and available in mass production quantities.
• Regulatory — RoHS compliant, meeting EU restrictions on hazardous substances.

Typical Applications

• Power Supplies — Bulk capacitance and rated ripple current make this capacitor suitable for smoothing and energy buffering on mid‑voltage DC rails.
• Industrial Power Electronics — Designed for applications operating at elevated temperatures and continuous ripple, such as motor drives and control power sections.
• Switch‑Mode Power Converters — High ripple current handling at both low and high frequencies supports filtering and decoupling in switching regulator outputs and input stages.
• General Purpose Electronic Equipment — Use where durable bulk capacitance and long life at 105°C are required for reliable operation across a wide temperature range.

Unique Advantages

• Long life at elevated temperature: 3000 hours endurance at 105°C provides predictable aging behavior for designs exposed to high thermal stress.
• Robust ripple performance: Specified ripple currents of 2.97 A (120 Hz) and 3.416 A (50 kHz) allow handling of both mains and switching noise without premature degradation.
• High bulk capacitance in a compact can: 4700 µF in a φ25 × 50L package delivers significant energy storage for space‑constrained power boards.
• Wide operating temperature: −40°C to +105°C supports deployment across diverse environmental conditions.
• Production‑ready packaging: Tray packing and mass production status simplify procurement and assembly planning.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for global products.
