LKG2A222MESAAK

The LKG2A222MESAAK from Nichicon is an aluminum electrolytic capacitor in a snap‑in radial can designed specifically for audio equipment. It provides high capacitance (2.2 mF) at a 100 V rating with a compact φ25 × 45 mm package for power‑supply and filtering applications in high‑fidelity audio designs.

Engineered as part of the LKG series (TYPE‑I / Gold Tune), this snap‑in component combines low loss (tan δ 0.25), a rated ripple current of 3.2 A (120 Hz), and specified endurance performance to support reliable operation in demanding audio systems across −40 °C to +85 °C.

Key Features

• High Capacitance & Voltage: 2.2 mF (2200 µF) capacitance at a 100 V rated voltage for energy storage and bulk filtering in audio power rails.
• Audio‑Grade Design: Part of Nichicon’s LKG series and specified as TYPE‑I (Gold Tune) for applications prioritizing high‑fidelity sound quality.
• Low Dissipation: Specified tan δ of 0.25 (measurement at 120 Hz, 20 °C) to minimize loss and heating in audio circuits.
• Ripple & Leakage: Rated ripple current of 3.2 A at 120 Hz and a listed leakage current figure of 1400 µA for predictable performance in power filtering.
• Robust Endurance: Designed for 1000 hours at 85 °C with defined limits on capacitance change, tan δ, and leakage after endurance testing.
• Package & Mounting: Snap‑in radial can (φ25 × 45 mm; size L: 4.5 × D: 2.5 cm) for secure chassis or board mounting in compact audio assemblies.
• Operating Range & Compliance: −40 °C to +85 °C operating temperature range and RoHS compliant.

Typical Applications

• High‑Fidelity Audio Amplifiers: Bulk energy storage and decoupling for power stages where low loss and reliable ripple handling are required.
• Professional Audio Equipment: Power supply filtering in studio and pro‑audio gear where sustained performance and endurance at elevated temperatures matter.
• Consumer High‑End Audio Systems: Supply smoothing and transient support for systems that prioritize sound quality and stable DC rails.

Unique Advantages

• Audio‑Focused Specification: LKG series TYPE‑I designation targets high tone quality and fidelity requirements in audio applications.
• High Energy Density: 2.2 mF at 100 V delivers substantial charge capacity in a compact φ25 × 45 mm package for space‑constrained designs.
• Low Loss Operation: tan δ of 0.25 reduces internal dissipation, supporting cooler operation and consistent audio performance.
• Reliable Ripple Handling: 3.2 A ripple current rating at 120 Hz supports aggressive smoothing demands in audio power supplies.
• Endurance‑Specified: 1000 hours at 85 °C endurance rating with defined post‑test limits gives designers a clear reliability target for thermal stress.
• Regulatory Compliance: RoHS compliance supports use in designs requiring restricted‑substance conformance.
