LGU1H682MELC

The LGU1H682MELC is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series. It delivers high capacitance (6800 µF / 6.8 mF) at a 50 V rating in a radial, snap‑in can package designed for general‑purpose electronic applications.

Engineered for sustained operation at elevated temperatures, this part offers a combination of high ripple current capability, low leakage, and 3000 hours endurance at 105°C—making it suitable where bulk energy storage and robust power filtering are required.

Key Features

• High Capacitance: 6800 µF (6.8 mF) nominal capacitance for bulk energy storage and filtering in power systems.
• 50 V Rated Voltage: Designed and rated for 50 V operation with ±20% capacitance tolerance at 120 Hz, 20°C.
• Snap‑In Radial Can Package: φ35 × 30 mm can with snap‑in terminals for secure board mounting and easy installation; tray packing for production use.
• Ripple Current Performance: 3.31 A at 120 Hz (low frequency) and 3.8065 A at 50 kHz (high frequency) to handle AC ripple stress in power circuits.
• Low Leakage: Rated leakage current of 1740 µA (measured after voltage application at 20°C) to minimize standby losses.
• Loss‑Angle (tan δ): tan δ of 0.30 max at 20°C and 120 Hz, specified for the 50 V rating.
• Wide Operating Temperature and Endurance: -40°C to +105°C operating range with 3000 hours endurance at 105°C under rated ripple and DC bias per LGU series specifications.
• RoHS Compliant: Meets RoHS directive requirements for lead‑free manufacturing and environmental compliance.

Typical Applications

• Power Supplies and Converters: Bulk capacitance and high ripple current capability support smoothing and energy buffering in DC power stages.
• Industrial Equipment: Robust temperature endurance and snap‑in mounting suit general‑purpose industrial electronics requiring long operational life at elevated temperatures.
• General‑Purpose Electronic Systems: Useful wherever high capacitance, defined leakage, and reliable ripple handling are needed in board‑level power designs.

Unique Advantages

• High Bulk Energy Density: 6800 µF in a compact φ35 × 30 mm can provides significant capacitance without excessive board area.
• Reliable High‑Temperature Endurance: 3000 hours rated life at 105°C supports designs exposed to sustained thermal stress.
• Designed for Ripple Duty: Specified ripple current values at both low and high frequencies reduce risk of overheating and extend service life under AC bias conditions.
• Predictable Electrical Behavior: Specified tan δ and leakage current give clear parameters for thermal and loss budgeting in power designs.
• Production‑Ready Packaging: Tray packing and snap‑in terminations simplify assembly for volume manufacturing.
• Regulatory Compliance: RoHS compliance supports use in lead‑free production environments.
