LKG1H682MESAAK

The LKG1H682MESAAK from Nichicon is a snap‑in, aluminum electrolytic capacitor specified at 6800 µF and 50 V, designed for high‑grade audio equipment. As a TYPE‑I (AK) "Gold Tune" variant in the LKG series, it is intended to prioritize high‑fidelity sound quality in audio applications.

This component offers a compact φ25 × 45 mm can in a radial snap‑in package, RoHS compliance, and documented endurance and leakage characteristics suitable for audio power supply and signal‑chain designs. Note: this part is designated End Of Life.

Key Features

• Capacitance and Voltage — 6.8 mF (6800 µF) rated at 50 V for bulk energy storage in audio power systems.
• Tolerance and Polarization — ±20% capacitance tolerance and polarized construction for predictable system-level behavior.
• Low Loss Design — Specified tan δ of 0.3 (measurement at 120 Hz, 20°C) to support audio fidelity in signal‑sensitive circuits.
• Ripple Handling — Rated ripple current of 3.3 A at 120 Hz, suitable for smoothing and reservoir duties in audio power supplies.
• Temperature and Endurance — Operating range −40°C to +85°C with endurance rated at 1000 hours at 85°C per series specifications.
• Package and Mounting — Radial, can-type snap‑in package (φ25 × 45 mm) for secure chassis or board mounting in audio equipment assemblies.
• Leakage Current Specification — Series leakage definition: after 5 minutes at rated voltage and 20°C, leakage current not to exceed 3√(C·V) µA, providing predictable loss characteristics.
• Compliance — RoHS compliant in accordance with the LKG series declaration.

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk energy storage and power smoothing to support clean, stable supply rails for amplifier stages.
• Audio Power Supplies — Reservoir and filter capacitor for reducing ripple and maintaining steady DC during dynamic audio loads.
• Preamp and Signal‑Chain Support — Low‑loss, high‑capacitance solutions where preservation of audio character is prioritized.

Unique Advantages

• Audio‑Focused Design — TYPE‑I "Gold Tune" grade tailored for high‑grade audio equipment to emphasize sound quality.
• High Capacitance in a Compact Can — 6800 µF in a φ25 × 45 mm package enables substantial energy storage without excessive board area.
• Predictable Ripple and Endurance — 3.3 A ripple rating at 120 Hz and 1000‑hour endurance at 85°C support reliable operation in audio power rails.
• Engineered Loss Characteristics — Specified tan δ and defined leakage behavior aid designers in maintaining audio performance targets.
• Snap‑in Mounting for Secure Assembly — Radial snap‑in configuration simplifies mechanical retention in chassis and power modules.
• Regulatory Compliance — RoHS compliance supports modern manufacturing and environmental requirements.
