LKG1K122MESCCK

The LKG1K122MESCCK is an aluminum electrolytic, snap‑in (lug) terminal capacitor from Nichicon's LKG series, engineered for audio equipment. It delivers 1.2 mF (1200 µF) capacitance at an 80 V rating in a compact radial can (φ35 × 25 mm).

Designed with audio performance in mind, this Type‑III (CK) variant incorporates gold‑plated terminal features from the LKG family and targets applications requiring high voltage headroom, robust ripple handling, and stable operation across –40 °C to +85 °C.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance, suitable for higher‑voltage audio circuits and power rails.
• Audio‑Grade Construction — Type‑III (CK) grading in the LKG series indicates the series’ high‑tone quality design and adoption of gold‑plated terminal features intended for audio applications.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.2, measured at 120 Hz and 20 °C, supporting low dissipation in signal and power filtering roles.
• Ripple Current Capability — Rated ripple current of 2.95 A at 120 Hz, enabling effective smoothing and decoupling in demanding audio power supplies.
• Leakage Performance — Leakage current specified at 920 µA (per product specification after rated voltage application and standard test conditions), aiding predictable bias performance.
• Reliability & Lifetime — Endurance rating of 1000 hours at 85 °C with capacitance change within ±20% and stable tan δ and leakage characteristics after endurance testing.
• Package & Mounting — Radial, snap‑in can (φ35 × 25 mm) intended for snap‑in mounting and supplied in tray packing for board assembly workflows.
• Operating Range — Rated for operation from –40 °C to +85 °C, providing stability across typical audio equipment environmental conditions.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Power supply filtering for audio amplifiers — Provides bulk energy storage and smoothing on high‑voltage rails in professional and consumer audio amplifiers.
• Decoupling and rail stabilization — Smooths transient loads and reduces ripple on power rails feeding sensitive analog stages.
• High‑fidelity audio equipment — Used in systems where sound quality and stable power delivery are prioritized, leveraging the LKG series’ audio‑focused design.
• Professional audio electronics — Suitable for mixing consoles, studio gear, and high‑grade playback equipment requiring reliable high‑voltage capacitors.

Unique Advantages

• High voltage capability: 80 V rating gives extra headroom for high‑voltage audio circuits and power supply designs.
• Audio‑focused terminal finish: TYPE‑III (CK) designation reflects LKG series features such as gold‑plated terminal adoption, targeted at tone quality and low contact drag.
• Strong ripple handling: 2.95 A ripple current at 120 Hz supports demanding smoothing duties in power supplies and amplifier rails.
• Compact, snap‑in form factor: φ35 × 25 mm radial can with snap‑in terminals provides a space‑efficient solution for through‑hole PCB mounting.
• Durability under elevated temperature: 1000‑hour endurance at 85 °C ensures predictable long‑term behavior in warmer enclosure environments.
• Industry‑friendly compliance: RoHS compliance supports environmental requirements for commercial and professional equipment.
