12106D226KAT2A

The AVX 12106D226KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and energy storage applications across industrial and commercial electronics. As a surface-mount component in the 1206 package size, this capacitor offers a compact footprint suitable for modern printed circuit board layouts where space efficiency is critical. Multilayer ceramic capacitors represent one of the most widely deployed passive components in electronics manufacturing. They are valued for their reliability, cost-effectiveness, and ability to perform consistently across a broad range of operating conditions. The 1206 package format—measuring approximately 3.2mm by 1.6mm—provides a practical balance between miniaturization and ease of handling during assembly processes. This size is standard across consumer, industrial, and automotive applications, making it a staple in board designs where moderate capacitance values are needed without requiring surface area that larger packages would demand. The "D" designation in AVX's numbering scheme typically indicates a specific dielectric material class, which influences the capacitor's temperature stability, voltage rating, and capacitance characteristics. Engineers selecting this particular part number would generally be looking for a capacitor suitable for mainstream power distribution, AC coupling, or transient filtering tasks where performance and reliability are expected across standard industrial temperature ranges. Common applications for components of this type include power supply bypass networks, high-frequency signal conditioning, EMI filtering, and general decoupling on mixed-signal circuit boards. The compact 1206 form factor makes it particularly popular in space-constrained designs where designers must pack multiple decoupling capacitors near integrated circuits or where board real estate is at a premium. Advantages of specifying the AVX 12106D226KAT2A over alternative solutions typically center on AVX's manufacturing consistency, established supply chain reliability, and proven performance in high-volume production environments. Engineers often select components from established manufacturers when designing products intended for mass manufacturing, as this reduces qualification risk and simplifies long-term sourcing. The standardized package and material composition also facilitate straightforward integration with automated assembly processes and standard printed circuit board fabrication methods. This capacitor would typically be encountered in industrial control systems, telecommunications equipment, data acquisition modules, and various embedded systems where ceramic capacitor performance and size constraints align with the 1206 format. Its role, while appearing passive, is essential to proper circuit function and system reliability across diverse temperature and operational scenarios.
