LKG1K681MESZCK

The LKG1K681MESZCK is a snap‑in terminal aluminum electrolytic capacitor tailored for audio equipment. It is part of Nichicon’s LKG series and is configured as a TYPE‑III (Super Through) audio grade component intended to prioritize high tone quality in high‑fidelity audio designs.

This capacitor delivers 680 µF at 80 V with performance characteristics aimed at audio applications: rated ripple handling of 2.25 A (120 Hz), low leakage, a 1000‑hour endurance at 85 °C, and an operating temperature range from ‑40 °C to 85 °C. The part is supplied in a radial, snap‑in can (φ22 × 35 mm) and is RoHS compliant. The part is listed as End Of Life/Discontinued.

Key Features

• Electrical Performance — 680 µF capacitance with ±20% tolerance and an 80 V rated voltage for higher‑voltage audio circuits.
• Audio Grade Construction — LKG series TYPE‑III (CK) grade targeting high tone quality for HD audio equipment, using design choices intended to prioritize sound fidelity.
• Loss and Leakage — Specified tangent of loss angle (tanδ) of 0.2 at 20 °C/120 Hz and a measured leakage current of 690 µA, supporting stable low‑loss operation in audio signal environments.
• Ripple Current Capability — Low‑frequency ripple current rating of 2.25 A at 120 Hz to handle power variation in audio power supplies and related circuits.
• Endurance and Temperature Range — Rated for 1000 hours at 85 °C with operating range from ‑40 °C to 85 °C, providing predictable life and stability under defined thermal stress.
• Package and Mounting — Radial, snap‑in can (φ22 × 35 mm) for secure board mounting; supplied in tray packing for handling and assembly.
• Compliance — RoHS compliant per the product data.

Typical Applications

• High‑fidelity audio amplifiers — Used where tone quality and stable power filtering are important for audio performance.
• Professional audio equipment — Specified for use in HD audio systems that prioritize sonic characteristics and long‑term stability.
• Audio component manufacturing — Suitable for assembly into audio power sections requiring snap‑in mounting and defined electrical endurance.

Unique Advantages

• Audio‑focused grade (TYPE‑III – Super Through) — Component coding (CK) aligns this part with Nichicon’s highest tone‑quality grade in the LKG series.
• High voltage capability — 80 V rating enables use in higher‑voltage portions of audio power networks.
• Robust ripple handling — 2.25 A ripple current at 120 Hz addresses low‑frequency power variations common in audio systems.
• Predictable endurance — 1000‑hour rating at 85 °C gives a clear specification for lifetime planning and thermal derating.
• Low loss and leakage — Specified tanδ and measured leakage current support low‑distortion, stable operation in audio paths.
• Snap‑in mechanical retention — Radial, snap‑in can offers secure panel/board mounting and efficient assembly handling.

Why Choose LKG1K681MESZCK?

LKG1K681MESZCK is positioned for designers and manufacturers of high‑grade audio equipment who need a defined combination of capacitance, voltage headroom, ripple capability, and audio‑centric construction. The TYPE‑III (Super Through) designation and the LKG series design choices emphasise tonal quality while providing measurable electrical endurance and stability.

This part is appropriate for projects where specifying vendor‑documented performance (capacitance, tanδ, leakage, ripple current, and 1000‑hour endurance at 85 °C) is important to system behavior and lifetime planning. RoHS compliance and tray packaging facilitate integration into production lines where these attributes are required.
