LKG1C123MESYAK

The LKG1C123MESYAK is a snap‑in aluminum electrolytic capacitor in the Nichicon LKG series, specified at 12,000 µF and 16 V. It is part of a family developed for audio equipment and HD audio applications where high capacitance and stable low‑frequency performance are required.

Key electrical and environmental characteristics include a low‑frequency ripple current rating of 2.25 A (120 Hz), a tangent of loss angle (tanδ) of 0.35 measured at 20 °C/120 Hz, leakage current specified at 1,310 µA, and an operating temperature range from −40 °C to +85 °C. The unit is supplied in a radial, snap‑in can (φ20 × 40 mm) package and is RoHS compliant.

Key Features

• High Capacitance: 12,000 µF nominal capacitance for bulk energy storage and low‑frequency smoothing in power rails.
• Rated Voltage: 16 V working voltage suitable for common audio power supply rails and intermediate DC bussing.
• Electrical Performance: Tanδ 0.35 (20 °C, 120 Hz) and leakage current 1,310 µA provide documented dissipation and leakage characteristics for design verification.
• Ripple Current Capability: Low‑frequency ripple current rated at 2.25 A (120 Hz) to support audio power amplifier and supply filtering demands.
• Temperature and Endurance: Specified operating range −40 °C to +85 °C with endurance of 1,000 hours at 85 °C under rated voltage, enabling conservative lifetime planning.
• Mounting and Package: Snap‑in radial can package (φ20 × 40 mm) for secure PCB attachment and high current handling in vertical assemblies.
• Capacitance Tolerance: ±20% at 120 Hz, 20 °C for predictable design margins.
• Regulatory Compliance: RoHS compliant, aligning with restricted substance requirements.

Typical Applications

• High‑Fidelity Power Supplies: Bulk energy storage and smoothing on audio amplifier power rails where high capacitance and 2.25 A ripple capability reduce low‑frequency ripple.
• Audio Amplifiers and Preamps: Supply decoupling and reservoir capacitance in systems designed for HD audio performance.
• Professional Audio Equipment: Use in mixers, powered speakers, and studio gear that require reliable filtering across −40 °C to +85 °C operating conditions.

Unique Advantages

• Large Energy Density: 12,000 µF provides substantial bulk capacitance in a compact φ20 × 40 mm can for tight board layouts.
• Audio‑Focused Design: LKG series development emphasizes audio performance, supporting use in high‑grade and HD audio equipment.
• Documented Endurance: 1,000 hours at 85 °C under rated voltage offers a measurable basis for life‑expectancy calculations.
• Robust Ripple Handling: 2.25 A (120 Hz) low‑frequency ripple rating helps maintain stable supply rails in demanding audio applications.
• Assembly‑Friendly Mounting: Snap‑in radial can format simplifies mechanical retention and PCB installation for vertical power modules.
• Regulatory Alignment: RoHS compliance supports designs requiring restricted‑substance conformity.
