LKG2A681MESYAK

The LKG2A681MESYAK is a snap‑in aluminum electrolytic capacitor from Nichicon's LKG series, engineered for audio equipment and HD audio applications. It delivers 680 µF capacitance at a 100 V rating in a compact snap‑in radial can (φ20x30L) with Type‑I (Gold Tune) audio‑grade characteristics.

Key electrical attributes include a low‑frequency ripple current of 1.7 A (120 Hz), low leakage current (780 µA), and an endurance rating of 1000 hours at 85°C. Note: this part is listed as End Of Life.

Key Features

• Capacitance & Tolerance — 680 µF with ±20% tolerance (measured at 120 Hz, 20°C), suitable where sizable bulk capacitance is required.
• Rated Voltage — 100 V rating for higher headroom in power supply and audio circuits.
• Audio‑Grade Design — LKG series specified "For Audio Use" and the suffix AK indicates TYPE‑I (Gold Tune) grade intended for high‑tone quality audio equipment.
• Ripple & Loss — Low frequency ripple current 1.7 A at 120 Hz and tangent of loss angle (tan δ) 0.25 (measured at 20°C, 120 Hz) for predictable AC behavior in audio power stages.
• Leakage Current — Specified leakage current of 780 µA, measured after rated voltage application.
• Endurance & Temperature — 1000 hours endurance at 85°C; operating temperature range −40°C to 85°C.
• Package & Mounting — Snap‑in radial can package (φ20x30L) with snap‑in mounting for secure board attachment; physical size approximately L: 3 × D: 2 cm and maximum seated height 1.181 inch.
• Compliance — RoHS compliant.

Typical Applications

• High‑fidelity audio equipment — Designed for use in audio devices where tonal quality and stable filtering are important.
• HD audio systems — Suited to audio subsystems in consumer and professional HD audio equipment that require audio‑grade capacitors.
• Audio power supplies — Bulk filtering and decoupling in power rails for amplifiers and preamps where 100 V rating and ripple handling are required.

Unique Advantages

• Audio‑oriented electrochemistry — Part of the LKG series with TYPE‑I (Gold Tune) grade, prioritizing tonal quality for audio applications.
• High voltage capability — 100 V rating provides extra margin for higher‑voltage audio power stages and extended headroom.
• Measured AC performance — Specified ripple current (1.7 A at 120 Hz) and tan δ values enable reliable selection for low‑frequency filtering tasks.
• Compact snap‑in package — Radial, snap‑in can (φ20x30L) offers a space‑efficient solution with secure mounting for chassis or PCB assemblies.
• Endurance data provided — 1000 hours at 85°C endurance specification supports design planning for lifecycle and reliability expectations.
• Regulatory compliance — RoHS compliant for designs requiring restricted‑substance conformity.
