0805YA180FAT2A

The 0805YA180FAT2A is a thin-film chip capacitor manufactured by AVX, supplied in the widely-used 0805 surface-mount package. This component belongs to the general category of high-stability, precision capacitors designed for applications where reliable performance and minimal drift over time are critical requirements. Thin-film capacitors like this model are constructed using vacuum-deposited metallic films on a ceramic substrate, which gives them superior stability compared to conventional thick-film alternatives. The 0805 package format is one of the most prevalent in modern electronics, offering a compact footprint measuring approximately 2.0mm by 1.25mm, making it ideal for dense circuit board layouts while remaining easy to handle and place using standard automated assembly equipment. The "YA" designation within this part number indicates this is a ceramic capacitor with specific electrical characteristics optimized for general-purpose coupling, decoupling, and filtering applications across consumer, industrial, and telecommunications equipment. Engineers frequently specify thin-film capacitors from established manufacturers like AVX when circuit designs require predictable capacitance values, low equivalent series resistance (ESR), and stable performance across typical operating temperature ranges. Common application areas for capacitors in this product family include signal conditioning circuits, power supply filtering, high-frequency coupling and decoupling networks, and timing circuits where capacitor value stability directly impacts circuit performance. The 0805 package makes these components particularly suitable for portable equipment, industrial control modules, audio electronics, and any space-constrained design where miniaturization is important without sacrificing reliability. Designers often choose AVX thin-film capacitors in this series when they need predictable parasitic behavior, low dielectric absorption, and consistent performance over extended operational life. Compared to larger package alternatives, the 0805 format reduces board area and assembly costs while maintaining the electrical characteristics required for precision applications. For engineers designing equipment destined for industrial or harsh environments, the thin-film construction provides better moisture resistance and temperature stability than many ceramic alternatives. The specific part number 0805YA180FAT2A represents a particular capacitance value within AVX's standard 0805 thin-film lineup. This component would typically be selected by design engineers who have determined that this exact capacitance value, combined with the reliability and stability characteristics of AVX's thin-film technology, best satisfies their circuit requirements. Procurement of this specific manufacturer and part number ensures consistent performance across production batches and design revisions.
