LKG1V122MESACK

The LKG1V122MESACK from Nichicon is an aluminum electrolytic capacitor in the LKG series, featuring a snap‑in (lug) terminal and a polarized radial can package. It provides 1.2 mF (1200 µF) capacitance at a 35 V rated voltage and is engineered for audio equipment applications where capacitor characteristics influence tonal quality.

Key electrical characteristics include a low loss angle (tan δ = 0.22), ripple current handling of 1.4 A at 120 Hz, specified leakage current of 610 µA, and an endurance rating of 1000 hours at 85 °C. The part is RoHS compliant and is listed as End of Life.

Key Features

• Electrical Capacity — 1.2 mF (1200 µF) nominal capacitance with ±20% tolerance, suitable for energy storage and smoothing in audio power rails.
• Voltage Rating — 35 V rated voltage for mid‑rail audio and power supply applications.
• Low Loss — tan δ = 0.22 (measurement reference: 120 Hz at 20 °C), supporting low dissipation in audio circuits.
• Ripple Handling — 1.4 A ripple current specification at 120 Hz to tolerate dynamic load currents in amplifier and power stages.
• Leakage Current — Specified leakage current of 610 µA, enabling predictable bias behavior after voltage application.
• Reliability & Lifetime — Endurance rating of 1000 hours at 85 °C; designed to meet the LKG series endurance characteristics after restoration to 20 °C.
• Package & Mounting — Radial can with snap‑in/lug terminals for secure chassis or PCB mounting in compact footprints (φ25 × 25L case).
• Environmental Compliance — RoHS compliant, meeting applicable directive requirements noted for the LKG series.
• Audio‑Centric Design — Part of Nichicon’s LKG family developed for high‑grade audio equipment, prioritizing fidelity and tonal quality.

Typical Applications

• High‑fidelity audio amplifiers — Bulk energy storage and power‑supply smoothing where low loss and ripple handling preserve audio performance.
• Preamp and DAC power rails — Decoupling and reservoir capacitance to stabilize supply voltages and reduce noise in sensitive audio circuits.
• Audio power supplies — Filtering and smoothing in regulated or unregulated supplies used in consumer and professional audio equipment.
• High‑grade audio equipment chassis — Snap‑in mounting simplifies secure installation in compact audio assemblies and enclosures.

Unique Advantages

• Audio‑focused construction: Part of the LKG family designed specifically for audio equipment, providing characteristics aligned with high‑fidelity applications.
• Predictable loss and leakage: Specified tan δ and leakage current values facilitate repeatable circuit behavior and easier tuning of analog audio stages.
• Robust ripple capability: 1.4 A ripple current rating at 120 Hz supports demanding amplifier power rails and transient loads.
• Endurance at elevated temperature: 1000 hours at 85 °C endurance rating gives a measurable reliability baseline for thermal design and life‑cycle planning.
• Snap‑in mounting for secure installation: Radial, snap‑in can simplifies mounting in audio chassis or board assemblies where mechanical stability is required.
• Regulatory compliance: RoHS compliance aligns the component with common electronics regulatory requirements.
