LKG1H682MESCBK

The LKG1H682MESCBK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, engineered for audio equipment. It combines a 6800 µF capacitance with a 50 V rating in a φ35 × 40 mm can to support power storage and smoothing needs in high‑grade audio systems.

Designed with audio fidelity in mind, this snap‑in capacitor offers measurable characteristics—such as low‑frequency ripple handling and defined loss tangent—useful for designers of amplifiers, speaker systems and audio power supplies requiring stable DC filtering and energy reserve.

Key Features

• Electrolytic Core Aluminum electrolytic construction providing 6800 µF nominal capacitance for bulk energy storage and filtering in audio circuits.
• Rated Voltage 50 V working voltage suitable for common audio power supply rails and amplifier circuits.
• Snap‑in Mounting & Package Snap‑in terminal, radial can package (φ35 × 40 mm; L: 4 × D: 3.5 cm) for secure chassis or PCB mounting in rack and enclosure designs.
• Audio‑focused Design Part of the LKG series developed for high‑grade audio equipment, prioritizing fidelity‑oriented performance characteristics.
• Ripple & Loss Characteristics Low frequency ripple current of 3.95 A (120 Hz) and specified tan δ (DF) of 0.3 measured at 20°C, 120 Hz to help predict behavior in power filtering roles.
• Leakage & Tolerance Specified leakage current 1740 µA and capacitance tolerance ±20% (at 120 Hz, 20°C) for predictable DC bias and sizing considerations.
• Operating Range & Endurance Rated for −40°C to +85°C with 1000 hours endurance at 85°C, enabling use in audio equipment operating across typical indoor environmental ranges.
• Regulatory RoHS compliant.
