LKG2A681MESZAK

The LKG2A681MESZAK is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKG series, designed for audio equipment and high-fidelity applications. This radial can package provides 680 µF capacitance at a 100 V rating with a compact φ22 × 25 mm profile for board-level power filtering and energy storage.

Built for audio-focused designs, the part combines a 1000-hour endurance at 85 °C, polarized construction, and a ripple-current rating suited to typical low-frequency power-supply environments.

Key Features

• Capacitance and Tolerance — 680 µF nominal capacitance with ±20% tolerance (specified at 120 Hz, 20 °C).
• Voltage Rating — 100 V rated working voltage for higher headroom in audio power supply circuits.
• Ripple Current — 1.75 A ripple-current rating at 120 Hz, supporting smoothing and decoupling in low-frequency power stages.
• Leakage Current — Specified leakage current listed as 780 µA, consistent with electrolytic capacitor behavior at rated conditions.
• Endurance and Temperature — 1000 hours lifetime at 85 °C; operating temperature range from −40 °C to +85 °C for a wide set of ambient conditions.
• Package and Mounting — Radial, snap-in can (φ22 × 25L) for secure board mounting and straightforward assembly into power modules and amplifier chassis.
• Polarized — Designed for polarized circuit use typical of power supply and smoothing applications in audio equipment.
• RoHS Compliant — Meets applicable RoHS requirements as stated for the LKG series.

Typical Applications

• High‑fidelity audio amplifiers — Bulk reservoir and power-supply smoothing where stable capacitance and rated voltage support low-frequency dynamics.
• Professional audio equipment — Power decoupling and energy storage in mixing consoles, preamps, and audio processing racks.
• Consumer audio electronics — Power-stage filtering in receivers and integrated amplifiers that require rated voltage headroom and reliable endurance.

Unique Advantages

• Audio-oriented design — Part of the LKG series developed with priority on sound quality for audio equipment applications.
• High voltage capability — 100 V rating provides design margin in higher-voltage audio and power-supply topologies.
• Compact snap-in form factor — φ22 × 25 mm radial can with snap-in terminals simplifies chassis and PCB integration while maintaining a robust mechanical mount.
• Endurance at elevated temperature — 1000 hours at 85 °C supports long-term operation in typical equipment enclosures.
• Ripple handling for power stages — 1.75 A ripple-current rating (120 Hz) supports smoothing duties in transformer-rectifier and similar supplies.
• Regulatory alignment — RoHS compliance aligns the component with common environmental requirements.
