LKG1K122MESZAK

The LKG1K122MESZAK is an aluminum electrolytic capacitor in a radial snap‑in can package, specifically from Nichicon's LKG series designed for audio equipment. It provides 1,200 µF capacitance at an 80 V rated voltage with polarized terminals and snap‑in mounting for secure chassis installation.

This part targets high‑fidelity audio applications where stable bulk capacitance, elevated voltage capability, and robust ripple handling are required. Key electrical characteristics include a rated ripple current of 1.95 A at 120 Hz, leakage current around 920 µA, and an operational temperature range of -40 °C to +85 °C with 1,000 hours endurance at 85 °C.

Key Features

• Capacitance & Voltage — 1,200 µF rated capacitance at 80 V provides substantial energy storage for audio power stages and supply filtering.
• Packaging & Mounting — Radial, snap‑in can package for secure chassis or board mounting in power modules and audio enclosures.
• Temperature & Endurance — Designed for operation from -40 °C to +85 °C with a rated lifetime of 1,000 hours at 85 °C.
• Ripple Current — Rated ripple current of 1.95 A at 120 Hz, suitable for low‑frequency power conditioning in audio systems.
• Leakage Current — Leakage current approximately 920 µA (typical product data); datasheet provides the standard limit of ≤ 3√(C·V) μA after 5 minutes at 20 °C.
• Audio‑Focused Series Design — Part of the LKG family developed for audio use with series attributes that prioritize high tone quality and fidelity.
• RoHS Compliant — Meets RoHS directive requirements as stated for the LKG series.

Typical Applications

• High‑grade audio amplifiers — Bulk energy storage and smoothing for amplifier power supplies where audio fidelity is a priority.
• HD audio playback systems — Used in audio equipment designed for high tone quality and low‑noise performance consistent with the LKG series focus.
• Audio equipment chassis assemblies — Snap‑in radial can package simplifies mechanical mounting in racks and enclosures.

Unique Advantages

• High voltage capability: 80 V rating supports higher‑voltage audio power rails and increases design headroom compared with lower‑voltage electrolytics.
• Substantial capacitance in a compact can: 1,200 µF provides significant bulk storage in a φ22 × 30 mm form factor (L: 3 × D: 2.2 cm), helping stabilize supply rails.
• Robust ripple handling: 1.95 A ripple current at 120 Hz supports low‑frequency power conditioning common in audio power supplies.
• Wide operating range and proven endurance: Rated for -40 °C to +85 °C with 1,000 hours endurance at 85 °C for reliable operation in equipment enclosures.
• Series design tuned for audio: LKG series engineering emphasizes tone quality and high‑fidelity use cases, aligning component selection with audio system requirements.
• Regulatory compliance: RoHS compliance supports environmental and regulatory needs for modern electronics manufacturing.
