LGU1H682MELB

The LGU1H682MELB is a Nichicon LGU series snap‑in aluminum electrolytic capacitor specified for general‑purpose applications. It delivers 6.8 mF (6800 µF) capacitance at a 50 V rating in a radial snap‑in can designed for high ripple endurance.

Engineered for elevated operating stress, this part supports continuous operation to 105 °C with rated ripple current endurance and is RoHS compliant, making it suitable where sustained capacitance, ripple handling and long life are required.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance with a 50 V rated voltage and tolerance of ±20% at 120 Hz, 20 °C.
• High Ripple Capability — Low‑frequency ripple current of 3.39 A at 120 Hz and high‑frequency ripple current of 3.898 A at 50 kHz, supporting sustained AC superposition applications.
• Thermal Endurance — Rated for continuous operation from −40 °C to 105 °C with a guaranteed endurance of 3000 hours at 105 °C under rated ripple conditions.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.30 (measurement condition: 20 °C, 120 Hz), useful for evaluating dissipation in designs.
• Leakage Current — Specified leakage current of 1740 µA after rated voltage application, measurable per the datasheet condition.
• Package & Mounting — Radial snap‑in can (φ30 × 35L mm), tray packed for handling and PCB snap‑in mounting for secure mechanical fit and straightforward assembly.
• Compliance — RoHS compliant, supporting regulatory requirements for lead‑free processes.

Typical Applications

• General‑purpose power supplies — Bulk energy storage and smoothing where high capacitance and sustained ripple handling are required.
• Industrial power electronics — Filtering and decoupling in assemblies that operate across −40 °C to 105 °C and require long endurance at elevated temperature.
• DC bus and energy buffering — Applications that need large capacitance and measurable ripple current capability for transient energy demands.

Unique Advantages

• Long thermal life: 3000 hours endurance at 105 °C under rated ripple current provides predictable durability in high‑temperature environments.
• Strong ripple performance: High specified ripple currents at both low and high frequencies reduce voltage ripple and support stable operation under AC stress.
• High bulk capacitance: 6.8 mF nominal value supplies substantial energy storage in a compact φ30 × 35 mm can for space‑sensitive designs.
• Snap‑in mounting: Radial snap‑in terminals simplify mechanical retention and assembly into power electronics boards.
• Clear electrical characterization: Specified tan δ and leakage current values enable straightforward thermal and loss budgeting in designs.
• Regulatory readiness: RoHS compliance supports integration into lead‑free manufacturing flows.
