LKG1K122MESYBK

The LKG1K122MESYBK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, specified at 1.2 mF (1200 µF) and 80 V. It is designed for audio equipment and high‑grade audio applications where reliable power filtering and tone quality are priorities.

Built for through‑hole snap‑in mounting, this part delivers audio‑focused performance with a compact radial can package and an operating temperature range of −40 °C to +85 °C. It carries RoHS compliance and an endurance rating of 1000 hours at 85 °C.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance, suited for higher‑voltage rail filtering in audio power stages.
• Audio‑Focused Design — Part of the LKG series specified “For Audio Use” and aligned with the series’ Gold Tune grade (TYPE‑II, code BK) for prioritized tone quality in high‑fidelity equipment.
• Electrical Loss & Ripple — Specified tangent of loss angle (tan δ) 0.25 and rated ripple current of 2.45 A at 120 Hz, supporting steady performance under AC ripple loads.
• Leakage Current — Specified leakage current of 920 µA (manufacturer condition references apply), aiding predictable bias behavior in audio circuits.
• Package & Mounting — Radial, snap‑in can package (φ20 × 50 mm nominal dimensions) for secure board retention and straightforward through‑hole assembly.
• Reliability & Thermal Endurance — Endurance specified as 1000 hours at 85 °C; capacitive change, tan δ and leakage current limits are defined for post‑endurance verification.
• Environmental Compliance — RoHS compliant.

Typical Applications

• High‑Fidelity Audio Equipment — Bulk and rail filtering where audio tone quality and stable supply decoupling are important.
• Professional Audio Power Supplies — Energy storage and ripple smoothing in amplifier and preamplifier power sections.
• Studio and Broadcast Gear — Use in systems requiring predictable endurance at elevated temperatures and consistent electrical characteristics over time.

Unique Advantages

• Audio‑oriented grade: The LKG series and the BK grade designation align this part with design priorities for high‑grade audio equipment and tone quality.
• High voltage capability: An 80 V rating supports higher rail designs without needing parallel capacitors or additional spacing for voltage headroom.
• Measured AC handling: A rated ripple current of 2.45 A at 120 Hz provides defined performance for power supply ripple conditions common in audio circuits.
• Endurance at elevated temperature: Qualified for 1000 hours at 85 °C, enabling predictable long‑term behavior in warm operating environments.
• Snap‑in mechanical retention: Radial snap‑in construction simplifies through‑hole assembly and secures the part against mechanical stress on the PCB.
• Regulatory compliance: RoHS compliance supports use in markets requiring restricted‑substance conformance.
