LGY1V472MELA25

The LGY1V472MELA25 is a Nichicon LGY series aluminum electrolytic capacitor in a snap‑in terminal radial can. It delivers 4.7 mF (4700 µF) capacitance at a 35 V rating in a compact φ25×25L package suitable for board-mounted power applications.

Designed for long-life operation, this snap‑in capacitor is specified for 5000 hours at 105°C and is RoHS compliant, making it a practical choice for industrial power supplies, ballast equipment, and general-purpose power-filtering roles where dependable long-term performance is required.

Key Features

• Capacitance & Voltage: 4.7 mF (4700 µF) rated at 35 V for bulk energy storage and smoothing.
• Long-life Endurance: Rated for 5000 hours at 105°C under rated ripple conditions, providing extended operational life in high-temperature environments.
• Ripple Current Performance: Low-frequency ripple current 1.8 A (120 Hz) and high-frequency ripple current 2.07 A (50 kHz) to support demanding power supply ripple loads.
• Dielectric Loss (tan δ): tanδ (DF) 0.35 measured at 20°C, 120 Hz, indicating the specified dissipation characteristic at the rated voltage.
• Leakage Current: Leakage current specified at 1210 µA after voltage application, for predictable standby and bias behavior.
• Operating Range: Wide operating temperature from −40°C to +105°C to accommodate industrial temperature profiles.
• Package & Mounting: Snap‑in terminal, radial can package (φ25×25L) for robust board attachment and tray packing for assembly handling.
• Capacitance Tolerance: ±20% (at 120 Hz, 20°C), matching common power-electronic design allowances.
• RoHS Compliant: Meets RoHS directive requirements for environmentally conscious designs.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and filtering in industrial supplies where long-life ripple endurance at elevated temperatures is required.
• Ballast Equipment: Energy storage and ripple handling in ballast circuits as indicated for the LGY series.
• General Purpose Power Filtering: Decoupling and energy reservoir duties in general-purpose electronic and power systems.

Unique Advantages

• Designed for long-term high-temperature operation: 5000 hours rated life at 105°C supports reliability targets in hot environments.
• High ripple capability: 1.8 A (120 Hz) and 2.07 A (50 kHz) ripple ratings accommodate both low- and high-frequency ripple conditions.
• Compact snap-in format: φ25×25L radial can with snap‑in terminals provides secure PCB mounting and straightforward mechanical retention.
• Predictable electrical characteristics: Specified tanδ (0.35 at 35 V, 120 Hz, 20°C) and defined leakage current enable accurate power-supply performance modeling.
• Regulatory compliance: RoHS compliance supports environmental requirements for commercial and industrial products.
