LKG2A681MESABK

The LKG2A681MESABK is a Nichicon LKG series aluminum electrolytic capacitor in a snap‑in, radial can package designed for audio applications. It delivers 680 µF capacitance at a 100 V rating with polarized terminals and a compact φ25 × 30 mm form factor.

Optimized for audio equipment, this TYPE‑II (BK) grade from the LKG family targets high‑fidelity sound applications while providing robust ripple handling, defined lifetime at elevated temperature, and RoHS compliance.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 100 V for bulk energy storage and decoupling in audio power supply circuits.
• Tolerance — ±20% capacitance tolerance (at 120 Hz, 20 °C) for predictable filtering performance.
• Ripple Current — 2.1 A ripple current rating at 120 Hz to support power conditioning under AC ripple loads.
• Leakage Current — Listed leakage current of 780 µA; series specification limits leakage to ≤ 3√CV (μA) after 5 minutes at 20 °C.
• Temperature & Lifetime — Operating range −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C.
• Package & Mounting — Radial, snap‑in can package (φ25 × 30 mm) for secure PCB mounting in power/audio assemblies.
• Audio‑Focused Grade — TYPE‑II (BK) grade within the LKG series, specified for audio use and tuned for high‑fidelity equipment.
• Regulatory — RoHS compliant as noted in the series documentation.

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk supply smoothing and decoupling in power stages where audio quality is prioritized.
• Professional Audio Equipment — Power conditioning for mixers, studio monitors, and other equipment calling out audio‑grade capacitors.
• Audio Power Supplies — Reservoir and filter capacitor in power supply sections where elevated voltage rating and ripple capability are required.

Unique Advantages

• Audio‑Oriented Design: TYPE‑II (BK) grade tailored for high‑fidelity audio applications, supporting sonic performance goals specified by the LKG series.
• High Voltage Headroom: 100 V rating provides margin for higher‑voltage audio power rails and robust transient handling.
• Compact Snap‑In Form Factor: φ25 × 30 mm radial snap‑in can simplifies board layout and secures mechanical mounting in chassis applications.
• Measured Ripple Capability: 2.1 A ripple current (120 Hz) supports typical audio power supply ripple conditions without excessive heating.
• Defined Endurance: 1000 hours at 85 °C endurance rating gives a clear expectation of life under elevated temperature operation.
• Regulatory Compliance: RoHS compliance supports use in products requiring restricted‑substance conformity.
