LGY1J182MELA25

The LGY1J182MELA25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGY series, engineered for long-life operation in demanding power applications. It delivers 1.8 mF capacitance at a 63 V rating in a compact φ25 × 25 mm can, with a polarized snap-in mounting style suited to high-reliability assemblies.

Designed for industrial power supplies and ballast equipment, this part emphasizes extended endurance and dependable ripple handling, backed by a 5000-hour life rating at 105°C and RoHS compliance.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) rated at 63 V, ±20% tolerance for bulk energy storage and decoupling in power circuits.
• Long-life Endurance — Rated for 5000 hours at 105°C under the specified ripple and DC bias conditions, providing predictable life for industrial applications.
• High Ripple Current Capability — Handles 1.60 A at 120 Hz (low frequency) and 1.84 A at 50 kHz (high frequency) to support heavy ripple loads in power converters and ballasts.
• Thermal & Environmental Range — Operates from −40°C to +105°C and is RoHS compliant.
• Electrical Loss & Leakage — Specified tangent of loss angle (tan δ) of 0.25 at 20°C and 120 Hz for the 63 V rating, and a leakage current value of 1010 µA as supplied.
• Package & Mounting — Radial, snap-in can (φ25 × 25 mm) for secure PCB retention; supplied in tray packing for production handling.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and ripple suppression where extended high-temperature endurance and high ripple capability are required.
• Ballast Equipment — Energy storage and ripple handling in lamp ballast circuits, leveraging the LGY series’ long-life design.
• General Purpose Power Filtering — Decoupling and bulk capacitance in industrial and commercial power electronics that demand stable performance over time and temperature.

Unique Advantages

• Extended High-Temperature Lifetime: 5000 hours at 105°C ensures predictable performance and reduced maintenance cycles in hot operating environments.
• Robust Ripple Handling: Rated ripple currents of 1.60 A (120 Hz) and 1.84 A (50 kHz) accommodate both low- and high-frequency ripple in switch-mode and magnetic ballast circuits.
• Compact Snap-In Package: φ25 × 25 mm radial can with snap-in terminals provides reliable PCB retention and easy assembly for medium-density power boards.
• Measurable Electrical Characteristics: Specified tan δ (0.25 at 63 V, 120 Hz, 20°C) and defined leakage current (1010 µA) support predictable design verification and margining.
• RoHS Compliant: Meets environmental directives for use in regulated markets.
