LKG1H681MESZCK

The LKG1H681MESZCK is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LKG series, specified at 680 µF and 50 V. It is designed for audio equipment and HD audio applications where component selection prioritizes sound quality and stable performance.

Key electrical and reliability attributes include a loss tangent (tanδ) of 0.22, a rated operating range of −40 °C to +85 °C, and an endurance specification of 1000 hours at 85 °C. The part is supplied in a radial can with snap‑in mounting and tray packing for production handling.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C).
• Audio‑focused design — Part of the LKG series developed for audio use; described in the series documentation as intended for high‑grade audio equipment and HD audio needs.
• Electrical loss — Specified tangent of loss angle (tanδ) of 0.22 (measurement frequency 120 Hz at 20 °C).
• Reliability & Endurance — Endurance defined as 1000 hours at 85 °C with post‑test limits: capacitance change within ±20%, tanδ up to 200% of initial specified value, and leakage current ≤ initial specified value.
• Leakage current specification — After 5 minutes at rated voltage and 20 °C, leakage current is specified as not more than 3√(C·V) µA (C in µF, V in V) per series documentation.
• Temperature range — Operation from −40 °C to +85 °C, suitable for typical audio equipment ambient conditions noted in the datasheet.
• Package & Mounting — Radial can, snap‑in terminal type (φ22 × 25 L profile) for secure board mounting; supplied in tray packing for handling and assembly.
• RoHS compliant — The product is RoHS directive compliant as indicated in the series documentation.

Typical Applications

• High‑fidelity audio equipment — Specified for use in designs where high tone quality and audio fidelity are priorities.
• HD audio systems — Intended for HD audio equipment as described in the LKG series materials.
• Professional and consumer audio devices — Suited to audio-centric products that call out audio‑grade passive components from the LKG family.

Unique Advantages

• Designed for audio fidelity: Part of the LKG series developed with audio performance in mind, supporting applications that prioritize sound quality.
• Measured loss characteristics: A specified tanδ of 0.22 at 120 Hz (20 °C) provides a defined loss profile for designers to use in performance tradeoffs.
• Conservative endurance rating: 1000 hours at 85 °C with documented post‑test limits gives predictable long‑term behavior in specified environments.
• Clear leakage current criterion: Leakage current limit defined by 3√(C·V) µA after 5 minutes at 20 °C supports predictable bias behavior.
• Production‑friendly packaging: Tray packing and snap‑in radial can format facilitate handling and installation in assembly processes.
• Wide operating temperature: −40 °C to +85 °C range aligns with typical ambient conditions encountered in audio equipment.
