LGU1K472MELB

The LGU1K472MELB is a snap‑in aluminum electrolytic capacitor from Nichicon's LGU series, offering 4.7 mF (4700 µF) capacitance at a rated voltage of 80 V. It is a radial, can‑style, snap‑in terminal capacitor designed for general‑purpose electronic equipment requiring high ripple handling and long endurance.

Key value propositions include a broad operating temperature range (−40 °C to 105 °C), rated performance for 3000 hours at 105 °C, and robust ripple current capability across low and high frequencies—making it suitable for demanding power applications within its specified ratings.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance, suitable for bulk energy storage and smoothing within the specified rating.
• Snap‑In Radial Package — Snap‑in terminal, radial can package (φ30 × 45L) for secure panel/PCB mounting and mechanical stability in assemblies.
• High Endurance — Rated for 3000 hours at 105 °C under specified conditions, meeting the LGU series’ endurance criteria for long‑term operation at elevated temperature.
• High Ripple Current Capability — Low‑frequency ripple current of 3.52 A at 120 Hz and high‑frequency ripple current of 4.048 A at 50 kHz, supporting sustained AC ripple stress within rating.
• Controlled Losses — Dissipation factor (tan δ) of 0.2 measured at 20 °C and 120 Hz (for the 80 V rating), providing predictable loss characteristics for power designs.
• Leakage Current — Specified leakage current of 1830 µA (after rated voltage applied for 5 minutes at 20 °C), enabling designers to account for standby and leakage budgets.
• Wide Temperature Range — Operates from −40 °C to 105 °C, matching the LGU series’ specified category temperature range for 16 to 250 V parts.
• Compliance & Packaging — RoHS‑compliant and supplied in tray packing; part is in mass production.

Typical Applications

• General‑purpose power supplies — Bulk smoothing and ripple handling within 80 V rated systems where high ripple current and extended endurance are required.
• Industrial electronic modules — Power filtering and energy storage in industrial control and support circuits operating across −40 °C to 105 °C.
• Commercial electronics — Use in general electronic equipment that requires a reliable radial snap‑in capacitor with documented endurance and ripple specifications.

Unique Advantages

• Long endurance at elevated temperature — 3000 hours at 105 °C provides predictable lifetime performance for designs exposed to sustained heat.
• High ripple handling across frequencies — Specified ripple currents at 120 Hz and 50 kHz allow designers to size components with clear AC stress limits.
• Clear electrical characterization — Quantified tan δ (0.2 at 20 °C, 120 Hz) and leakage current values support accurate thermal and loss budgeting in power systems.
• Robust mechanical mounting — Snap‑in radial can package (φ30 × 45L) offers secure installation for board and chassis configurations.
• Regulatory compliance — RoHS‑compliant construction supports environmental requirements for commercial and industrial products.
• Production readiness — Tray packing and mass production status simplify procurement and integration for volume projects.
