18123C473KAT2A

The AVX 18123C473KAT2A is a multilayer ceramic capacitor (MLCC) from AVX's established component family. This part represents a common choice for industrial electronics, telecommunications equipment, and general-purpose circuit boards where reliable energy storage and signal filtering are essential. Multilayer ceramic capacitors are passive components designed to store electrical energy and filter signals across a wide range of applications. They function by creating an electric field between conductive layers separated by ceramic dielectric material, enabling capacitance in a compact form factor. The 18123C series designation indicates this is part of AVX's proven portfolio of surface-mount capacitors engineered for demanding industrial environments. This component utilizes a surface-mount package configuration, making it suitable for automated assembly processes and modern printed circuit board designs where space efficiency is important. The compact profile allows engineers to maximize board real estate while maintaining robust electrical performance. AVX capacitors in this series are recognized for consistent quality and long-term reliability, which is particularly valuable in applications where component replacement or maintenance is costly or impractical. Industrial applications for components like this include power supply circuits, where they stabilize voltage regulation and filter ripple; signal conditioning in measurement and instrumentation systems; coupling and decoupling in audio and RF circuits; and timing networks in control electronics. Telecommunications infrastructure, industrial automation systems, and consumer electronics manufacturing frequently incorporate MLCCs from this family. Engineers often specify AVX components for their established track record of performance consistency and availability across supply chains. AVX maintains comprehensive manufacturing standards and quality certifications that make this part suitable for mission-critical applications. The multilayer ceramic construction provides stable performance across temperature ranges typical in industrial settings and resistance to mechanical stress during manufacturing and field deployment. Compared to alternative dielectric technologies, multilayer ceramic capacitors offer excellent volumetric efficiency—delivering substantial capacitance values in minimal board space—alongside low equivalent series resistance (ESR) and inductance characteristics that make them effective at high frequencies. This makes them preferable to some alternatives in filtering applications where performance consistency matters. The part number structure indicates specific electrical characteristics optimized for particular circuit requirements. Engineers selecting this exact part number would typically be targeting a capacitor with particular capacitance value, voltage rating, and tolerance specifications suited to their circuit design parameters. When component performance and reliability matter in industrial applications, the combination of AVX's manufacturing reputation and this part's inclusion in established product families makes it a standard specification choice.
