LGU1H682MELA

The LGU1H682MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, designed for general‑purpose power applications requiring high capacitance in a compact radial can. It delivers 6.8 mF at 50 V with a wide operating temperature range and robust endurance characteristics for reliable bulk energy storage and smoothing.

Built for applications that demand sustained ripple handling and long life at elevated temperatures, this part combines a snap‑in mounting style with a 105°C rated temperature capability and RoHS compliance.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) rated at 50 V, suitable for bulk filtering and energy storage.
• High‑temperature Endurance — Rated life of 3000 hours at 105°C with DC bias plus rated ripple current applied; meets LGU series endurance criteria.
• Ripple Current Performance — Rated ripple current of 3.37 A at 120 Hz and 3.876 A at 50 kHz, supporting sustained AC stress in power supply rails.
• Electrical Losses — Tangent of loss angle (tan δ) 0.30 (measured at 120 Hz, 20°C for the 50 V rating), enabling predictable ESR-related behavior.
• Leakage Current — Specified leakage current of 1740 µA, measured after standard voltage application conditions.
• Robust Packaging & Mounting — Radial, snap‑in can package for secure board retention; supplied in tray packing for handling and assembly.
• Wide Temperature Range — Operational from −40°C to +105°C, suitable for environments that require extended temperature tolerance.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling on 50 V rails where high capacitance and ripple endurance are required.
• Industrial Power Modules — Energy reservoir and ripple management in motor drives, inverters, and control power supplies operating up to 105°C.
• Telecom and Server Power — Bulk capacitance for intermediate bus or standby supplies that demand long life and stable performance under sustained ripple.

Unique Advantages

• Long High‑Temperature Life: 3000 hours at 105°C under rated ripple current helps extend equipment service intervals and reduces maintenance frequency.
• High Capacitance Density: 6.8 mF in a φ25×45L can provides significant energy storage in a compact footprint for space‑constrained designs.
• Snap‑in Mechanical Reliability: Snap‑in terminals provide secure board retention for high‑vibration and high‑current assemblies.
• Predictable Ripple Handling: Specified ripple currents at both low and high frequencies allow reliable thermal and lifetime planning in power designs.
• RoHS Compliance: Reduces material compliance risk for global product deployments.
