LGU1K472MELC

The LGU1K472MELC is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in, radial can package. It offers 4700 µF capacitance at an 80 V rated voltage and is designed for general‑purpose power applications requiring high ripple current handling and extended endurance.

Engineered for robust performance, this part combines a compact φ35 × 35 mm footprint with high ripple current capability and a wide operating temperature range, making it suitable for industrial and commercial power electronics where reliable bulk capacitance is needed.

Key Features

• High Capacitance — 4700 µF (4.7 mF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C for bulk energy storage and smoothing.
• 80 V Rated Voltage — Designed for up to 80 V DC systems, enabling use in higher‑voltage power rails.
• High Ripple Current Capability — 3.5 A at 120 Hz (low frequency) and 4.025 A at 50 kHz (high frequency) to support high‑stress power filtering and decoupling.
• 105°C Endurance — Rated lifetime of 3000 hours at 105°C under specified conditions, supporting long service life in elevated‑temperature environments.
• Wide Temperature Range — Operating from −40°C to +105°C for use across a broad set of ambient conditions.
• Snap‑In Radial Can Package — φ35×35L dimensions with snap‑in terminals for secure PCB mounting and high current handling; packaged in trays for mass production.
• Leakage Current — Specified leakage current of 1830 µA after rated voltage application, suitable for power system calculations and standby considerations.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Power Supplies — Bulk smoothing and filtering on higher‑voltage DC rails where 4700 µF and an 80 V rating are required.
• Industrial Power Electronics — Energy buffering and ripple absorption in converters and motor drive assemblies operating within the −40°C to +105°C range.
• Backup and Energy Storage Modules — Bulk capacitance for charge/discharge cycles that benefit from high ripple current capability and 3000 h endurance at 105°C.

Unique Advantages

• High ripple tolerance: 3.5 A (120 Hz) and 4.025 A (50 kHz) ripple ratings reduce heating and extend service life in high‑stress filtering roles.
• Extended high‑temperature life: 3000 hours at 105°C provides predictable endurance for designs exposed to elevated operating temperatures.
• Compact snap‑in form factor: φ35 × 35 mm can with snap‑in terminals simplifies PCB installation and supports robust mechanical retention for high‑current connections.
• Clear electrical parameters: Defined leakage current (1830 µA) and ±20% capacitance tolerance enable accurate system modeling and BOM decisions.
• Production ready: Tray packing and mass production status support volume assembly and procurement needs.
• Regulatory compliance: RoHS compliance helps meet environmental and regulatory requirements for commercial and industrial products.
