LGU1C473MELC

The LGU1C473MELC is a Nichicon LGU-series aluminum electrolytic capacitor in a snap-in terminal format, rated 16 V with 47,000 µF (47 mF) capacitance and ±20% tolerance. It is designed for general-purpose use where high bulk capacitance, high ripple handling and long endurance at elevated temperature are required.

Key attributes include a low-frequency tanδ of 0.50 (measured at 20°C, 120 Hz), rated ripple current capability and a guaranteed endurance of 3000 hours at 105°C, making it suitable for demanding power-filtering and bulk energy storage roles in industrial and commercial electronics.

Key Features

• Capacitance & Voltage – 47,000 µF (47 mF) nominal capacitance at a rated voltage of 16 V with ±20% tolerance, providing substantial bulk energy storage for smoothing and hold-up.
• Snap-in Radial Package – Radial, can-type snap-in mounting for secure mechanical retention and straightforward PCB assembly; packaged in trays and available in mass production quantities.
• High Ripple Current Capability – Rated ripple current of 5.53 A at 120 Hz and 6.359 A at higher frequency, supporting applications with significant AC ripple on DC rails.
• Low Loss Characteristics – Tangent of loss angle (tanδ) specified at 0.50 maximum (20°C, 120 Hz), enabling predictable ESR-related performance for power applications.
• Leakage Current – Specified leakage current of 2,600 µA, measured under rated conditions, for predictable standing loss in held or standby states.
• High-Temperature Endurance – Designed to withstand 3,000 hours of applied rated ripple current at 105°C with limits on capacitance change, tanδ and leakage current as specified.
• Operating Temperature Range – Specified for operation from −40°C to +105°C to support a broad range of environmental conditions.
• RoHS Compliant – Meets RoHS requirements for lead-free assembly environments.

Typical Applications

• General-purpose power filtering – Bulk smoothing and decoupling in power supplies and DC buses where large capacitance and ripple handling are required.
• High-ripple environments – DC link or intermediate bus filtering where elevated ripple currents are present, leveraging the part’s specified ripple current ratings.
• High-temperature electronics – Long-life applications that operate up to 105°C and require 3,000-hour endurance under rated ripple current.

Unique Advantages

• Substantial bulk capacitance: 47,000 µF provides significant energy storage per capacitor, reducing the number of parts needed for bulk filtering.
• High ripple tolerance: Rated ripple currents at both low and high frequencies enable reliable performance where AC components are present on DC rails.
• Long endurance at elevated temperature: 3,000 hours at 105°C under rated ripple current supports extended field life in warm operating environments.
• Predictable electrical behavior: Specified tanδ and leakage current figures allow engineers to budget ESR-related losses and standby leakage precisely.
• Production-ready supply: Tray packing and mass production status simplify procurement and assembly planning for higher-volume programs.
