LKG1E681MESYCK

The LKG1E681MESYCK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for audio equipment applications. It combines a 680 µF capacitance at 25 V with a radial snap‑in can package for board-level power filtering and decoupling in audio systems.

Designed with audio performance in mind, the LKG series prioritizes tone quality and high‑grade audio characteristics while offering engineered electrical stability and mechanical mounting suited to systems that require reliable smoothing and low‑frequency energy storage.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20%.
• Audio‑Oriented Design — Part of the LKG series developed for high‑grade audio equipment and intended to preserve audio fidelity in power supply and signal smoothing roles.
• Dissipation Factor (tan δ) — tan δ = 0.22 measured at 20°C, 120 Hz, supporting predictable AC loss characteristics in audio circuits.
• Ripple & Leakage — Low‑frequency ripple current of 650 mA (120 Hz) and leakage current specified at 390 µA, suitable for power filtering in audio amplifier circuits.
• Reliability & Endurance — Rated lifetime of 1000 hours at 85°C with endurance specifications for capacitance, tan δ, and leakage current after the test.
• Operating Range — Temperature range from −40°C to +85°C for broad environmental tolerance.
• Package & Mounting — Radial, snap‑in can package (φ20 × 20 mm) for secure board mounting and straightforward assembly; supplied in tray packing.
• RoHS Compliant — Conforms to applicable RoHS requirements.

Typical Applications

• Audio Power Supplies — Bulk smoothing and decoupling for amplifier rails and preamplifier power sections to help maintain stable supply under dynamic audio loads.
• High‑Fidelity Audio Equipment — Filtering and energy storage in high‑grade audio systems where component selection targets sound quality.
• Mixing Consoles & Signal Processing — Local supply filtering for analog stages to reduce low‑frequency ripple and support consistent performance.

Unique Advantages

• Purpose‑Built for Audio: LKG series design emphasis on tone quality aligns the capacitor’s electrical characteristics with audio system requirements.
• Compact Snap‑In Form Factor: φ20 × 20 mm radial snap‑in package provides robust mechanical retention and simplifies placement in power sections.
• Predictable Loss Characteristics: Specified tan δ at 20°C/120 Hz (0.22) enables designers to account for AC loss in filter and coupling applications.
• Low Leakage and Ripple Handling: 390 µA leakage and 650 mA ripple current rating at 120 Hz help maintain stable bias and filter performance under load.
• Endurance Under Load: 1000‑hour rating at 85°C offers defined long‑term behavior for systems operating in elevated temperatures.
• Regulatory Compliance: RoHS compliance supports use in designs requiring restricted‑substance conformance.
