The LKG2A122MESZBK is a snap‑in, large‑can aluminum electrolytic capacitor from Nichicon’s LKG series, designed specifically for audio equipment. It combines a 1.2 mF capacitance and a 100 V rated voltage in a radial, snap‑in can package suitable for high‑fidelity audio applications.

Key value propositions include a focus on audio performance and robustness across a wide temperature range, RoHS compliance, and a form factor optimized for snap‑in mounting. Note: this part is End Of Life.

Key Features

• Capacitance & Voltage – 1.2 mF (1200 µF) nominal capacitance with a 100 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• Audio‑focused design – Part of the LKG series developed for high‑grade audio equipment and HD audio needs, prioritizing high‑fidelity sound quality as described in the series documentation.
• Low‑frequency ripple capability – Rated low‑frequency ripple current of 3.0 A at 120 Hz, supporting demanding ripple conditions in audio power circuits.
• Loss characteristics – Tangent of loss angle (tan δ) specified at 0.25 (measured at 20°C, 120 Hz, 100 V), providing a quantified dissipation characteristic for audio designers.
• Leakage current – Leakage current reported as 1030 µA for this part.
• Temperature & endurance – Operating temperature range of −40°C to +85°C with 1000 hours rated endurance at 85°C per the series specification.
• Impedance stability at low temperature – Series impedance ratios: Z(−25°C)/Z(+20°C) = 4 and Z(−40°C)/Z(+20°C) = 12, providing guidance for low‑temperature performance.
• Package & mounting – Radial, snap‑in can package (φ22 × 50 mm) supplied in tray packing for board assembly.
• Environmental – RoHS compliant.

Typical Applications

• High‑grade audio equipment – Designed for use in devices where priority is given to high‑fidelity sound quality.
• HD Audio systems – Suited to audio applications described in the LKG series materials as meeting HD audio sound quality needs.
• Boards requiring snap‑in radial cans – Applicable where a snap‑in, large‑can aluminum electrolytic capacitor is preferred for assembly and mechanical stability.

Unique Advantages

• High voltage capability: The 100 V rating enables use on higher DC rails within audio equipment designs.
• Substantial stored energy: 1.2 mF capacitance provides significant bulk capacitance for audio power stages.
• Measured ripple capacity: 3.0 A low‑frequency ripple current rating (120 Hz) supports demanding ripple environments.
• Quantified dissipation: tan δ specified at 0.25 (20°C, 120 Hz, 100 V) gives precise loss information for thermal and audio performance assessments.
• Wide operating range and defined endurance: −40°C to +85°C operating range with a 1000‑hour endurance rating at 85°C for predictable long‑term behaviour.
• RoHS compliance: Meets RoHS directive requirements noted for the LKG series.
