LKG1K681MESACK

The LKG1K681MESACK is a polarized aluminum electrolytic capacitor in a snap‑in radial can designed for audio equipment. It delivers 680 µF capacitance at an 80 V rated voltage and is optimized where high‑fidelity audio performance and reliable power handling are required.

Its construction and electrical characteristics — including a specified tan δ and ripple current rating — make it suitable for smoothing and bulk energy storage in audio power supplies and related circuitry operating across a broad temperature range.

Key Features

• Capacitance & Tolerance — 680 µF nominal capacitance with ±20% tolerance (120 Hz, 20 °C).
• Rated Voltage — 80 V working voltage for higher‑rail audio and power supply designs.
• Loss Characteristics — tan δ 0.2 (measurement at 120 Hz, 20 °C) to quantify dielectric loss for audio applications.
• Ripple Current Handling — 2.15 A (120 Hz), supporting smoothing and decoupling under AC ripple conditions.
• Leakage Current — 690 µA specified leakage, measured after rated voltage application conditions.
• Operating Range & Endurance — −40 °C to +85 °C operating temperature with a rated endurance of 1000 hours at 85 °C.
• Package & Mounting — Snap‑in radial can (φ25 × 30 mm length) for board mounting and mechanical stability.
• RoHS Compliant — Conforms to RoHS directive as indicated in product documentation.

Typical Applications

• Professional and Consumer Audio Equipment — Bulk energy storage and smoothing in power supplies for amplifiers, preamps, and DACs where sound quality is a priority.
• Audio Power Supplies — Filtering and ripple attenuation on higher‑voltage rails up to 80 V, taking advantage of the capacitor’s rated ripple current.
• High‑Fidelity Signal Systems — Use in systems that demand consistent electrical characteristics across −40 °C to +85 °C and extended endurance at elevated temperature.

Unique Advantages

• High Voltage Capability: 80 V rating enables use on higher rail audio power supplies without up‑rating multiple lower‑voltage parts.
• Audio‑Focused Design: Series design and documentation indicate prioritization of tone quality and fidelity for audio equipment applications.
• Robust Ripple Handling: 2.15 A ripple current (120 Hz) helps maintain stable DC rails under AC loading typical in audio amplifiers.
• Operating Temperature & Endurance: −40 °C to +85 °C range with 1000‑hour endurance at 85 °C supports long‑term operation in varied environments.
• Compact Snap‑In Form Factor: φ25 × 30 mm snap‑in can provides a secure board mounting option and a small footprint for dense assemblies.
• Regulatory Compliance: RoHS compliance aligns with modern environmental requirements for electronic assemblies.
