1206YC222KAT2A

The AVX 1206YC222KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and coupling applications in electronic circuits. This component belongs to AVX's established Y5V dielectric family, which is recognized in the industry for delivering high capacitance density in a compact form factor. The part number designator "1206" refers to the industry-standard Surface Mount Device (SMD) package size of 1.2mm × 0.6mm, making it suitable for space-constrained PCB layouts common in modern consumer electronics, telecommunications equipment, and industrial control systems. This small footprint allows designers to achieve high component density while maintaining reliable automated assembly processes. The Y5V dielectric material in this capacitor provides a relatively high capacitance value in a small physical volume, making it particularly valuable when board space is limited. However, capacitance in Y5V ceramics exhibits greater temperature dependence compared to more stable dielectric classes, which is an important consideration during the design phase. This characteristic makes Y5V capacitors ideal for applications where temperature stability is less critical or where the circuit design compensates for capacitance variation. Multilayer ceramic capacitors like the 1206YC222KAT2A are widely used in power supply bypassing and decoupling roles, where they suppress high-frequency noise near integrated circuit power pins. They are also commonly employed in signal coupling circuits, filtering applications, and general energy storage functions in consumer electronics, automotive systems, industrial instrumentation, and communications equipment. Engineers typically specify this exact part when they require a standard, cost-effective MLCC in the 1206 package with the capacitance value indicated in the part number. AVX MLCCs in this family have established quality standards and reliable performance records across numerous applications. The combination of proven design, established supply chain presence, and predictable electrical behavior makes this part a dependable choice for designs requiring a high-volume, general-purpose ceramic capacitor. Designers selecting this component should verify that the Y5V dielectric characteristics and the 1206 package dimensions align with their circuit requirements, thermal environment, and manufacturing capabilities. The part is suitable for standard reflow soldering processes used in modern electronics manufacturing.
