LKG2A122MESYAK

The LKG2A122MESYAK from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor engineered for audio equipment. It belongs to the LKG series and is specified for high‑fidelity audio use with a compact φ20 × 45 mm can‑type snap‑in package.

Key electrical characteristics include 1.2 mF capacitance at 100 V rating, low frequency ripple current capability and a measured tanδ of 0.25 (120 Hz, 20°C). Note: this part is listed as End Of Life.

Key Features

• Electrical Capacity: 1.2 mF (1200 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C, providing significant low‑frequency energy storage.
• High Voltage Rating: 100 V rated voltage for applications requiring increased DC headroom.
• Low Loss: Tangent of loss angle (tanδ) 0.25 measured at 20°C, 120 Hz, supporting lower dielectric losses in audio signal paths.
• Ripple Handling: Low frequency ripple current 2.3 A at 120 Hz for sustained ripple filtering performance in power supply applications.
• Leakage Current: Specified leakage current of 1030 µA after rated voltage application and dwell, useful for design budgeting of standby currents.
• Reliability / Life: Endurance specified as 1000 hours at 85°C with defined post‑test limits for capacitance, tanδ and leakage current.
• Mechanical / Mounting: Snap‑in radial can (φ20 × 45 mm), tray packed for board assembly and service‑friendly installation.
• Temperature Range & Compliance: Rated for −40°C to +85°C operating range and RoHS compliant.
• Audio‑Grade Series: Part of the LKG series designed for high‑grade audio equipment; TYPE‑I (AK) grade denotes the Gold Tune, low‑profile tone quality variant.

Typical Applications

• High‑Fidelity Audio Amplifiers: Energy reservoir and power supply smoothing where large capacitance and 100 V withstand are required.
• Professional Audio Equipment: Power filtering and decoupling in mixers, preamps and audio processing racks that prioritize sound quality.
• Audio Power Supplies: Low‑frequency ripple handling and bulk storage for regulated and discrete power stages in audio systems.

Unique Advantages

• Substantial Energy Storage: 1200 µF capacitance gives designers usable bulk capacitance for low‑frequency filtering in audio power rails.
• High DC Headroom: 100 V rating supports designs requiring higher supply voltages or larger safety margins.
• Designed for Audio Fidelity: LKG series TYPE‑I (Gold Tune) construction targets tone quality and low loss characteristics relevant to audio paths.
• Robust Ripple Performance: 2.3 A ripple current rating at 120 Hz helps maintain stable filtering under AC ripple stress.
• Proven Endurance: 1000‑hour endurance at 85°C with specified post‑test limits provides measurable reliability parameters for life planning.
• RoHS Compliant: Meets RoHS directive requirements for restricted substances.
