LKG1C123MESCCK

The LKG1C123MESCCK is an aluminum electrolytic, snap‑in (radial can) capacitor from Nichicon’s LKG series, specifically developed for audio equipment. It delivers large bulk capacitance in a compact φ35 × 45 mm package and is designed to meet high‑tone quality requirements for HD audio and high‑grade audio systems.

Key electrical characteristics include 12,000 µF capacitance at 16 V, a measured tanδ of 0.25 (20 °C, 120 Hz), and a low‑frequency ripple current rating suitable for demanding audio applications. The part is rated for operation from −40 °C to +85 °C with a 1,000‑hour endurance at 85 °C.

Key Features

• Bulk Capacitance: 12,000 µF nominal capacitance with ±20% tolerance, delivering substantial energy storage for audio circuits that require sustained low‑frequency response.
• Rated Voltage: 16 V working voltage suitable for low‑voltage audio power stages and correlating power domains.
• Audio‑Grade Design (TYPE‑III / Super Through): Series and part coding indicate a TYPE‑III "Super Through" audio grade with gold‑tune characteristics and gold‑plated terminal adoption focused on tone quality.
• Loss and Ripple Performance: tanδ = 0.25 measured at 20 °C, 120 Hz, and a low‑frequency ripple current rating of 3.7 A (120 Hz), supporting stable performance under audio ripple conditions.
• Leakage Current: Specified leakage current of 1310 µA, provided for predictable bias and recovery behavior in audio circuits.
• Robust Endurance and Temperature Range: Rated for −40 °C to +85 °C with 1000 h endurance at 85 °C, enabling sustained operation in typical electronic enclosures and studio equipment.
• Package & Mounting: Snap‑in radial can (φ35 × 45 mm) for secure chassis or PCB mounting in through‑hole assemblies; supplied in tray packing.
• RoHS Compliant: Conforms to RoHS requirements as indicated in the product data.

Typical Applications

• High‑Grade Audio Equipment — Intended for use in high‑fidelity and HD audio systems where coloration and tone quality are important design considerations.
• Audio Power Stages — Provides large bulk capacitance for power reservoirs and decoupling in amplifier and preamplifier circuits within audio products.
• Studio and Consumer Receivers — Suitable for use in playback and amplification gear that prioritize consistent tonal performance over extended operating periods.

Unique Advantages

• High Bulk Energy Storage: 12,000 µF capacitance supplies substantial stored energy, reducing low‑frequency sag in audio power delivery.
• Audio‑Focused Construction: LKG series TYPE‑III (Super Through) grade with gold‑tune characteristics targets high‑tone quality needs for HD audio designs.
• Measured Loss Characteristics: Specified tanδ of 0.25 at 20 °C/120 Hz gives engineers a verifiable metric for dissipation and AC performance in audio bands.
• Designed for Ripple Handling: 3.7 A ripple current rating (120 Hz) supports typical low‑frequency ripple conditions found in audio power supplies.
• Temperature and Endurance Specified: −40 °C to +85 °C operating range with 1000 h endurance at 85 °C supports reliable operation in controlled electronic environments.
• Secure Snap‑In Mounting: Radial snap‑in can (φ35 × 45 mm) simplifies mechanical retention for through‑hole audio assemblies.
