LKG1C122MESZCK

The LKG1C122MESZCK is a snap‑in aluminum electrolytic capacitor from Nichicon's LKG series, specified at 1,200 µF and 16 V. It is designed for audio equipment and the LKG series emphasizes high‑fidelity sound performance in demanding audio applications.

This part combines a compact snap‑in radial can package with audio‑focused electrical characteristics — low loss (tan δ), high low‑frequency ripple capability, and defined endurance at elevated temperature — making it suitable for use where reliable power filtering and audio performance are required.

Key Features

• Capacitance & Tolerance — 1,200 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C.
• Rated Voltage — 16 V DC rating for mid‑rail audio and low‑voltage power systems.
• Low Loss — tan δ = 0.25 measured at 20 °C, 120 Hz to support low dissipation in audio signal and power circuits.
• Low‑Frequency Ripple Handling — 950 mA ripple current specified at 120 Hz, suitable for smoothing and filtering in audio power supplies.
• Leakage Current — 410 µA (specified value) after rated conditions.
• Endurance — 1,000 hours at 85 °C with performance limits defined for capacitance, tan δ and leakage current.
• Operating Range — Rated for −40 °C to +85 °C operating temperature range.
• Package & Mounting — Radial, snap‑in can (snap‑in terminal type) supplied in tray packing for board assembly.
• Audio Grade — TYPE‑III (Super Through) — Part suffix "CK" denotes the TYPE‑III grade within the LKG series, targeted at higher tone‑quality requirements per series documentation.
• Polarized — Electrolytic, polarized capacitor for DC power applications.
• RoHS Compliant — Meets RoHS requirements as stated in the product information.

Typical Applications

• High‑fidelity audio equipment — Filtering and energy storage in power supplies where low loss and audio performance are prioritized.
• Audio amplifiers — Bulk decoupling and smoothing on amplifier rails to support stable, low‑noise power delivery.
• Studio and consumer audio electronics — Use in systems that require reliable long‑term operation at elevated temperatures with controlled electrical characteristics.

Unique Advantages

• Audio‑focused design: The LKG series is developed specifically for audio use, with characteristics chosen to support high‑fidelity performance.
• Measured low loss: Specified tan δ at standard measurement conditions (20 °C, 120 Hz) helps minimize dissipation in critical audio circuits.
• Robust ripple capability: 950 mA ripple current at 120 Hz provides effective smoothing for low‑frequency power fluctuations common in audio power supplies.
• Defined endurance: 1,000 hours at 85 °C gives a clear expectation of long‑term performance under elevated operating temperatures.
• Compact snap‑in form factor: Radial snap‑in can in tray packing simplifies mechanical retention and board assembly for power sections in audio equipment.
• Regulatory compliance: RoHS compliance supports use in designs targeting regulatory adherence in applicable regions.
