LKG2A122MESAAK

The LKG2A122MESAAK is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKG series, developed specifically for audio equipment. This TYPE-I (AK) "Gold Tune" grade component is intended for high‑fidelity audio applications where stable filtering and power decoupling at elevated voltages are required.

Key electrical characteristics include 1.2 mF capacitance at 100 V rated voltage, a low-frequency ripple current rating of 2.35 A (120 Hz), and a rated operating range of −40 °C to +85 °C with 1000 hours endurance at 85 °C.

Key Features

• Audio‑Grade Design (TYPE‑I, Gold Tune) — Engineered for high‑grade audio equipment with emphasis on tone quality and fidelity as described in the LKG series documentation.
• Electrical Capacity — 1.2 mF (1200 µF) capacitance at 100 V provides substantial energy storage for power supply smoothing and decoupling in audio circuits.
• Ripple Handling — Low frequency ripple current 2.35 A at 120 Hz supports filtering of mains‑related ripple in audio power rails.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.25 (measured at 20 °C, 120 Hz), enabling predictable dissipation behavior in design calculations.
• Leakage and Tolerance — Leakage current listed at 1030 µA and capacitance tolerance ±20% (120 Hz, 20 °C) for accurate performance planning.
• Robust Thermal Endurance — Rated for −40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C, aligning with long‑term stability requirements.
• Snap‑in Package — Radial can, snap‑in mounting simplifies board installation and mechanical retention for power assemblies; size φ25 × 30 mm length for compact placements.
• RoHS Compliant — Meets RoHS directive requirements as noted in product documentation.

Typical Applications

• Audio Power Supplies — Bulk smoothing and decoupling on amplifier power rails where 100 V rating and high capacitance are required.
• High‑Fidelity Amplifiers — Energy storage and ripple suppression in high‑grade audio amplifiers to support consistent output under dynamic loads.
• Audio Signal/Power Modules — Use in modular audio equipment assemblies that require snap‑in mounting and reliable long‑term operation at elevated temperatures.

Unique Advantages

• Audio‑tuned Grade: The TYPE‑I (AK) "Gold Tune" designation indicates series design emphasis on tone quality for high‑grade audio equipment.
• High Voltage Capability: 100 V rated voltage enables use in higher‑headroom audio power supplies and designs that require elevated DC bus voltages.
• High Capacitance Density: 1200 µF in a φ25 × 30 mm can provides substantial charge storage in a compact snap‑in package.
• Predictable Ripple Performance: Specified 2.35 A ripple current at 120 Hz supports design margining for mains‑frequency smoothing tasks.
• Thermal Endurance: 1000 h at 85 °C endurance rating and −40 °C to +85 °C operating range give designers defined lifetime behavior under thermal stress.
• Regulatory Compliance: RoHS compliance helps meet environmental requirements for commercial audio equipment.
