1206CA680JAT1A

The 1206CA680JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the established leaders in passive component production. This component is housed in a 1206 surface-mount package, a standard size widely adopted across industrial and consumer electronics applications where moderate capacitance values and compact board real estate are required. Multilayer ceramic capacitors like this part serve as fundamental building blocks in modern electronic circuits. They function to store electrical charge, filter noise, decouple power supplies, and stabilize voltage rails across countless industrial control systems, consumer devices, and embedded applications. The 1206 package size represents a common middle ground in the MLCC landscape—larger than 0805 packages, offering improved current-handling capability, yet smaller than 1210 packages, making it suitable for space-constrained designs that still demand reliable performance. The "680J" designation in the part number indicates the capacitance value and voltage rating class. AVX's CA series represents a mature, proven platform for general-purpose capacitance applications across industrial, automotive, and telecommunications sectors. Components in this family are recognized for consistent performance and broad availability, making them practical choices for both new designs and legacy system maintenance. Engineers typically specify this exact part number when designing circuits that require a specific capacitance value in the 1206 footprint, with voltage and temperature characteristics suited to general industrial use. The AVX brand carries established reliability credentials and traceability documentation valuable in regulated industries or military applications. Designers often select parts from proven series like the CA line to reduce qualification risk and leverage existing supply chain relationships. Common applications include power supply decoupling in microcontroller-based systems, noise filtering in analog signal processing circuits, timing circuit stabilization, and general energy storage functions across industrial equipment, test instruments, and embedded systems. The 1206 package provides sufficient lead spacing for standard automated assembly processes and allows reasonable repair or rework capability if required during manufacturing or field service. When selecting this particular part, engineers benefit from AVX's manufacturing consistency, the established design history of the CA series, and the availability across multiple distribution channels. The 1206 footprint also ensures compatibility with standard PCB assembly processes and equipment calibrated for conventional surface-mount component sizes, reducing production complexity and cost compared to less common package options.
