LGY1K272MELA40

The LGY1K272MELA40 is a snap‑in terminal aluminum electrolytic capacitor designed for long‑life industrial power applications. It delivers 2700 µF capacitance at an 80 V rating in a radial can with snap‑in mounting, tailored for high‑reliability power filtering and energy‑smoothing roles.

Built for continuous operation to 105°C, the part supports sustained ripple handling and long endurance (5000 hours at 105°C), making it suitable for industrial power supplies, ballast systems and other general purpose power electronics where stable capacitance, ripple tolerance and longevity are required. The device is RoHS compliant and supplied in tray packing for production deployment.

Key Features

• Capacitance & Voltage: 2700 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance, providing bulk energy storage for mid‑voltage power rails.
• Snap‑in Radial Can: Snap‑in terminal type in a radial/Can package (φ25 × 40 mm) for secure PCB mounting and straightforward assembly in power modules.
• High Temperature Endurance: Rated operating range –40°C to +105°C with a specified endurance of 5000 hours at 105°C under rated ripple and DC bias.
• Ripple Current Capability: 2.2 A at 120 Hz (low frequency) and 2.53 A at 50 kHz (high frequency), enabling effective smoothing of both mains‑frequency and higher frequency ripple components.
• Leakage & Dissipation: Specified leakage current of 1390 µA and tan δ of 0.20 at 20°C/120 Hz (for the 80 V rating), supporting predictable loss and self‑heating behavior in designs.
• Manufacturing & Packaging: Tray packing and mass production status for reliable supply in volume production runs.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and output filtering where sustained ripple handling and long life at elevated temperatures are required.
• Ballasts: Designed for ballast applications called out in the series documentation, providing stable capacitance and endurance under continuous ripple stress.
• General Purpose Power Electronics: Use in general power filtering, smoothing and decoupling functions across industrial and commercial power systems.

Unique Advantages

• Long‑life specification: 5000 hours at 105°C endurance rating supports designs requiring extended operating life under thermal and ripple stress.
• Dual‑frequency ripple performance: Rated ripple current values for both 120 Hz and 50 kHz let designers assess performance across mains and higher frequency switching environments.
• High voltage margin: 80 V rating enables use on mid‑voltage rails while maintaining a compact φ25 × 40 mm package footprint.
• Predictable electrical loss: Specified tan δ (0.20 at 20°C/120 Hz) and measured leakage current provide clear parameters for thermal and leakage budgeting.
• Production‑ready packaging: Tray packing and mass production status simplify procurement and assembly planning for OEM production runs.
