LKG2A821MESAAK

The LKG2A821MESAAK is a snap‑in, large‑can aluminum electrolytic capacitor from Nichicon’s LKG series, optimized for audio equipment. It provides 820 µF capacitance at a 100 V rating in a radial snap‑in can (φ25 × 25 mm) intended for high‑fidelity audio applications.

Designed as a TYPE‑I (Gold Tune) grade in the LKG family, this capacitor combines a low‑profile, audio‑focused electrolyte formulation with electrical characteristics suitable for power smoothing and decoupling in audio power and signal systems.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 100 V rated voltage, providing bulk energy storage for audio power rails.
• Audio‑Grade Type — Designated TYPE‑I (AK) in the LKG series (Gold Tune), indicating the low‑profile, high‑tone‑quality electrolyte formulation specified for audio equipment.
• Loss and Frequency Performance — Tangent of loss angle (tanδ) of 0.25 measured at 20°C, 120 Hz (at 100 V), offering defined dissipation characteristics for audio applications.
• Ripple Current Handling — Low‑frequency ripple current rating of 1.8 A at 120 Hz, suitable for smoothing power supply ripple in audio amplifiers and related circuits.
• Leakage Current — Specified leakage current of 850 µA, enabling predictable bias conditions in high‑voltage audio systems.
• Reliability & Endurance — Endurance rated for 1000 hours at 85°C with defined limits on capacitance change, tanδ, and leakage after the endurance test.
• Package & Mounting — Radial, snap‑in can package (φ25 × 25 mm) with tray packing for PCB snap‑in mounting and straightforward mechanical retention.
• Temperature Range — Operates across –40°C to +85°C, accommodating common environmental conditions for professional audio equipment.
• RoHS Compliant — Meets RoHS directive requirements as stated for the LKG series.

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk smoothing and power decoupling on amplifier supply rails to support low‑noise, high‑power audio stages.
• Audio Power Supplies — Energy storage and ripple suppression in regulated or unregulated power supplies for audio systems.
• Studio and Pro‑Audio Equipment — Power reservoir and decoupling in mixers, preamplifiers, and outboard gear where stable supply rails are required.
• Passive/Active Crossovers and Filters — DC blocking and supply conditioning roles where the specified capacitance and voltage ratings are needed.

Unique Advantages

• Audio‑Focused Electrolyte: TYPE‑I (Gold Tune) designation indicates a formulation targeted at high‑tone‑quality performance suited for HD audio designs.
• High Voltage Capability: 100 V rating enables use in higher‑voltage audio power architectures and reserve headroom for peak conditions.
• Predictable Dissipation: Specified tanδ (0.25 at 20°C, 120 Hz) delivers consistent dissipation characteristics for design margin calculations.
• Robust Ripple Handling: 1.8 A ripple current rating at 120 Hz supports effective smoothing in power supplies for demanding audio loads.
• Endurance at Elevated Temperature: 1000‑hour rating at 85°C with defined recovery limits provides measurable long‑term behavior for thermal stress scenarios.
• Compact Snap‑In Form Factor: φ25 × 25 mm radial snap‑in can offers a compact, mechanically secure option for PCB mounting in audio chassis.
