LGY2A472MELC50

The LGY2A472MELC50 is a Nichicon LGY-series large-can, snap-in aluminum electrolytic capacitor rated at 4700 µF (4.7 mF) and 100 V. It is a snap-in terminal, radial can design intended for general-purpose power applications where high ripple tolerance and long operational life at elevated temperatures are required.

Designed for industrial power-supply and ballast use, the part combines high-voltage capability, significant ripple-current handling and a long endurance rating to support dependable performance in demanding environments.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) nominal capacitance with a rated voltage of 100 V and a capacitance tolerance of -20% to +20%.
• High Ripple-Current Capability — Low-frequency ripple current 3.2 A at 120 Hz and high-frequency ripple current 3.68 A at 50 kHz, enabling effective smoothing and filtering under heavy AC ripple conditions.
• Long Life Endurance — Rated for 5000 hours at 105°C with specified endurance criteria for capacitance, tan δ and leakage current after the endurance test.
• Electrical Loss and Leakage — Tangent of loss angle (tan δ) 0.2 (measured at 20°C, 120 Hz) and leakage current specified at 2050 µA for this part.
• Wide Operating Temperature Range — Specified for -40°C to +105°C to accommodate a broad range of industrial operating environments.
• Package & Mounting — Snap-in terminal radial can (φ35 × 50 mm) for secure PCB mounting; supplied in tray packing for handling and assembly.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing on high-voltage DC rails where high ripple current capability and long life at 105°C are required.
• Ballasts — Designed for ballast applications called out in the LGY series, providing stable capacitance and endurance under sustained ripple conditions.
• General-Purpose Power Filtering — DC link smoothing and power-filtering in industrial equipment and other general-purpose circuits that require a 100 V, high-capacitance snap-in solution.

Unique Advantages

• Long operational life: 5000 hours at 105°C provides predictable endurance for designs expected to operate at elevated temperatures.
• High-voltage capability: 100 V rating enables use on higher DC rails without compromising capacitance.
• Robust ripple performance: 3.2 A (120 Hz) and 3.68 A (50 kHz) ripple-current ratings reduce heating and support reliable filtering under heavy ripple loads.
• Wide ambient range: -40°C to +105°C operating range accommodates demanding industrial temperature profiles.
• Serviceable form factor: Snap-in radial can (φ35 × 50 mm) simplifies board mounting for large-capacitance, high-voltage applications.
• RoHS compliant: Simplifies regulatory compliance for assemblies requiring restricted-substance conformity.
