LGY1K682MELC45

The LGY1K682MELC45 is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LGY long‑life assurance series. It delivers 6.8 mF capacitance at an 80 V rated voltage in a radial, can-style snap‑in package.

Designed for industrial power electronics, this part is suited to applications that require dependable performance under elevated temperature and sustained ripple stress—Nichicon specifies a 5000‑hour ripple endurance at 105°C. The capacitor is RoHS compliant.

Key Features

• Capacitance and Voltage: 6.8 mF nominal capacitance with an 80 V rated voltage, suitable for bulk energy storage and filtering in high‑voltage power circuits.
• Long‑life Endurance: Specified to withstand 5000 hours of rated ripple current at 105°C, providing longevity under sustained thermal and electrical stress.
• Wide Operating Temperature: Rated for –40°C to +105°C operation, enabling use across a broad range of industrial environments.
• High Ripple Handling: Rated ripple current of 3.5 A at 120 Hz and 4.025 A at 50 kHz, supporting power supply filtering and ripple absorption in high‑stress applications.
• Mounting and Package: Snap‑in terminal, radial can package (snap‑in) for secure PCB retention and simplified assembly in power modules and chassis‑mounted systems.
• Tolerance and Polarization: Capacitance tolerance of –20% to +20%; polarized device—observe polarity in circuit installation.
• Physical Size: Package dimensions L: 4.5 × D: 3.5 cm with a maximum seated height of 1.772 inch, aiding layout planning for power supply assemblies.
• RoHS Compliance: Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and output filtering where sustained ripple endurance at elevated temperature is required.
