LKG1K222MESAAK

The LKG1K222MESAAK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series designed for audio equipment. It delivers 2200 µF of polarized capacitance at an 80 V rated voltage with a low loss tangent (tan δ) targeted for high‑tone quality applications.

Packaged in a radial, snap‑in can (φ25 × 35 mm), this component is specified for -40°C to +85°C operation, 1000 hours endurance at 85°C, and is RoHS compliant. Note: this part is listed as End of Life.

Key Features

• Capacitance & Voltage — 2200 µF capacitance rated at 80 V provides bulk energy storage for power rails and audio coupling in high‑voltage audio circuits.
• Tolerance — ±20% capacitance tolerance (120 Hz, 20°C) for predictable design margins.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.25, supporting applications where tone quality and low dissipation are important.
• Ripple Handling — Rated ripple current 2.75 A at 120 Hz to support smoothing and decoupling under AC ripple conditions.
• Leakage Current — Initial leakage current specified at 1250 µA, measured per product specifications after standard voltage application.
• Thermal & Reliability — Operating range -40°C to +85°C with endurance of 1000 hours at 85°C (meets specified capacitance, tan δ, and leakage limits after endurance).
• Mechanical & Mounting — Radial snap‑in can package (φ25 × 35 mm) for secure chassis/PCB mounting; supplied in tray packing.
• Environmental — RoHS compliant.

Typical Applications

• High‑fidelity audio amplifiers — Bulk storage and power smoothing where the LKG series’ audio‑oriented characteristics support tone quality.
• Professional audio equipment — Power supply decoupling and reservoir applications in mixers, preamps, and studio gear operating up to 80 V.
• Audio power supplies — Filtering and ripple suppression at 120 Hz with the specified 2.75 A ripple rating.

Unique Advantages

• Audio‑targeted design — Part of Nichicon’s LKG family developed for audio use, providing specifications (tan δ and capacitance) aligned to high‑tone applications.
• High‑voltage capability — 80 V rating enables use in higher‑voltage audio and power circuits without series stacking.
• Robust ripple performance — 2.75 A ripple current rating at 120 Hz supports effective smoothing under AC load conditions.
• Verified endurance — 1000 hours at 85°C endurance ensures retained capacitance and controlled tan δ and leakage after high‑temperature stress.
• Secure snap‑in mounting — Radial snap‑in can simplifies mechanical retention in chassis or PCB assemblies.
• RoHS compliance — Conforms to RoHS directive requirements for restricted substances.
