1206CA681MAT1A

The 1206CA681MAT1A is a ceramic multilayer capacitor manufactured by AVX, housed in the widely-adopted 1206 surface-mount package. This component belongs to the CA series family, which represents a mainstream line of general-purpose ceramic capacitors designed for reliable performance across consumer electronics, industrial control systems, and telecommunications equipment. Ceramic capacitors in the 1206 package are among the most common passive components in modern electronics. The 1206 designation refers to the physical dimensions of the chip, making it large enough to handle moderate capacitance and voltage requirements while remaining compatible with standard automated assembly equipment. This size strikes a practical balance between performance density and ease of installation in high-volume manufacturing environments. The CA series from AVX is engineered for applications requiring stable performance over temperature and voltage ranges typical of industrial and commercial-grade electronics. These capacitors use ceramic dielectric material, which offers several advantages for general-purpose applications: good frequency response, compact form factor, and cost-effectiveness. They are commonly specified in power supply filtering, signal coupling, timing circuits, and noise suppression applications where designers need reliable performance without exotic material requirements. Engineers typically select the 1206CA681MAT1A when they need a capacitor that balances several practical considerations. The 1206 package provides better volumetric efficiency than smaller packages like 0805 or 0603, which matters when designers need to meet specific capacitance targets without consuming excessive board space. Compared to larger packages, the 1206 remains compatible with standard pick-and-place assembly, avoiding hand-assembly costs and manufacturing delays. The CA series positioning makes this part suitable for applications where mid-range performance ceramic capacitors are appropriate, rather than demanding specialized high-voltage, high-temperature, or ultra-low-ESR variants. This component would typically appear in industrial control boards, power distribution modules, consumer appliances, and communication interface circuits. Its ceramic construction means it performs predictably in the voltage and temperature ranges encountered in standard industrial and commercial equipment. The part number suffix "MAT1A" indicates AVX's specific internal configuration and lead plating standard, ensuring consistent performance and compatibility with RoHS and other material compliance requirements. For engineers and procurement specialists sourcing components, the 1206CA681MAT1A represents a standardized, readily-available solution from an established manufacturer—factors that simplify supply chain management and support long-term production runs.
