1206YA103KAT2A

The 1206YA103KAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, packaged in the industry-standard 1206 surface-mount form factor. This component belongs to the Y5V dielectric class, which is commonly selected for applications where cost-effectiveness and compact board space are priorities, rather than the most stable or precise capacitive performance across temperature ranges. Multilayer ceramic capacitors in the 1206 package are among the most widely used passive components in modern electronics, suitable for high-volume manufacturing environments. The 1206 size (approximately 3.2 mm × 1.6 mm) provides a practical balance between component density and ease of handling during automated assembly. This particular part is designed for surface-mount placement on printed circuit boards, making it ideal for consumer electronics, industrial control systems, power supplies, automotive electronics, and telecommunications equipment. The Y5V dielectric classification indicates this capacitor is optimized for general-purpose applications rather than precision filtering or timing circuits. Y5V capacitors exhibit capacitance variation with temperature and applied voltage, making them well-suited for bulk energy storage, power supply decoupling, and general signal coupling applications. They are typically employed in non-critical filtering roles where moderate capacitance stability is acceptable and cost reduction is valued. Engineers typically specify the 1206YA103KAT2A when designing circuits that require a compact, reliable capacitor for mainstream industrial and commercial applications. The part's small package size enables tight PCB layouts while maintaining standard reel-and-tape packaging compatible with pick-and-place assembly equipment. AVX's manufacturing reputation ensures consistent quality and availability, which is important for production lines requiring dependable component supply. This capacitor is commonly found in power distribution networks, where it provides localized charge storage to support transient current demands on digital and analog circuits. It is also frequently used in input and output filtering stages of DC-DC converters, in EMI suppression circuits, and in general decoupling applications throughout industrial control boards. When selecting alternatives to this part, engineers must consider the specific electrical requirements of their circuit, including required capacitance value, voltage rating, operating temperature range, and acceptable capacitance tolerance. While other dielectric classes or package sizes might offer improved stability or different cost profiles, the 1206YA103KAT2A represents a proven choice in applications where the Y5V class performance characteristics align with design objectives.
