LGY1V392MELZ30

The LGY1V392MELZ30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGY series, offering 3.9 mF (3900 µF) nominal capacitance at a 35 V rating. Designed for board-level power applications, it delivers high ripple-current capability and long life performance in a compact radial can package.

Targeted at industrial power electronics and ballast applications, this polarized capacitor combines a 105°C rated operating temperature, a 5000-hour endurance at 105°C, and RoHS compliance to support reliable, long-term operation in demanding environments.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance rated at 35 V with ±20% tolerance (measured at 120 Hz, 20°C).
• High-temperature endurance — Qualified for 5000 hours of operation at 105°C when subjected to rated DC bias plus rated ripple current, meeting the LGY series long-life requirements.
• Ripple current capability — Handles 1.6 A rms at 120 Hz (low frequency) and 1.84 A at 50 kHz (high frequency), supporting demanding smoothing and filtering duty in power circuits.
• Electrical characteristics — Low-frequency tangent of loss angle tanδ = 0.35 (max.) at 35 V (120 Hz, 20°C) and leakage current specified at 1100 µA for this part.
• Package & mounting — Snap-in terminal radial can (22 mm diameter × 30 mm length) for secure board retention and robust current paths.
• Operating range & polarization — Polarized capacitor rated for −40°C to +105°C operation, suitable for sustained high-temperature use.
• Compliance & logistics — RoHS compliant, supplied in tray packing, and in mass production status for consistent availability.

Typical Applications

• Industrial power supplies — Bulk smoothing and output filtering where sustained ripple handling and elevated temperature endurance are required.
• Ballast circuits — Energy storage and filtering in ballast and lamp-driver applications as noted for the LGY series.
• Power modules and converters — Decoupling and energy buffering for board-level power electronics needing reliable ripple performance.

Unique Advantages

• Long life at elevated temperature — 5000-hour endurance at 105°C reduces maintenance and replacement frequency in high-heat installations.
• High ripple-current handling — 1.6 A (120 Hz) and 1.84 A (50 kHz) ratings support heavy smoothing loads without compromising performance.
• Compact, board-friendly form — 22 mm × 30 mm radial snap-in can provides a high-capacitance solution in a space-efficient package for PCB mounting.
• Predictable electrical behavior — Specified tanδ and leakage current figures allow precise thermal and loss budgeting in power designs.
• Regulatory compliance — RoHS-compliant construction supports deployment where restricted-substance conformance is required.
