12063G155ZAT2A

The 12063G155ZAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a leading supplier of passive electronic components. This part belongs to the 1206 package family, one of the most widely used surface-mount capacitor form factors in modern electronics manufacturing. Multilayer ceramic capacitors are fundamental passive components found in virtually every category of electronic equipment. They store electrical charge and are essential for filtering, decoupling, timing, and signal coupling applications across industrial control systems, telecommunications infrastructure, automotive electronics, consumer devices, and countless other domains. The 1206 package size represents a practical middle ground in the MLCC landscape—larger than the smaller 0603 or 0402 packages, which means it typically offers higher capacitance values and voltage ratings, yet remains compact enough for high-density circuit board layouts. The "G155" designation in this part number indicates this capacitor is part of AVX's established ceramic dielectric formulation and capacitance class. AVX's G-series capacitors are engineered to deliver stable performance across standard industrial temperature ranges, making them suitable for applications where reliability and predictable behavior are essential. The specific ceramics material class determines how capacitance changes with temperature, voltage, and frequency—considerations that design engineers carefully evaluate when selecting components for precision circuits. Engineers select this exact part number over alternatives for several reasons. First, the 1206 package offers a proven balance between performance and board space efficiency. Second, AVX's quality and consistency make this part suitable for applications requiring high reliability and traceability. Third, the G-series formulation provides capacitance stability characteristics that work well in many standard industrial and commercial applications. For designers working with established design guidelines or those upgrading existing products, specifying a proven part like this reduces development risk compared to qualifying entirely new components. The multilayer construction of ceramic capacitors provides excellent frequency response characteristics, making them effective at high frequencies while also handling DC blocking and power supply smoothing tasks. The 1206 package's moderate size also facilitates automated assembly processes, helping manufacturers maintain cost-effectiveness in volume production. This capacitor is commonly stocked by distributors because its combination of package size, performance class, and proven reliability makes it a standard choice across multiple industries and equipment categories. Design engineers familiar with the 1206 form factor and AVX's product quality often specify this part when their circuit requirements align with its capabilities.
