1206CA391JAT2A

The AVX 1206CA391JAT2A is a capacitor designed for general-purpose applications in industrial and commercial electronics. This component belongs to the thick-film chip capacitor category, featuring a 1206 surface-mount package that is widely standardized across the electronics industry. The 1206 package designation refers to physical dimensions of 3.2mm × 1.6mm, making it a moderately sized surface-mount component suitable for automated assembly on printed circuit boards. This package size represents a practical balance between component density and ease of handling, assembly, and rework—characteristics that make it popular in cost-sensitive production environments while remaining accessible for manual repair when needed. As a thick-film capacitor from AVX's established product lines, this part is typically used in coupling, decoupling, filtering, and bypass applications across various industrial control systems, telecommunications equipment, power supplies, and consumer electronics platforms. Thick-film chip capacitors generally offer reliable performance in mainstream temperature and voltage operating ranges, making them suitable for equipment that operates in typical industrial environments without extreme thermal or electrical stress. Engineers typically specify this exact part number when design requirements call for a compact, standard-package capacitor with proven manufacturing consistency and broad supplier availability. The 1206 format integrates seamlessly with high-volume PCB assembly processes, reducing setup costs and production complexity compared to selecting non-standard components. Additionally, the established nature of this part number in the industry means that long-term sourcing stability is generally achievable—an important consideration for equipment manufacturers planning extended production runs or long-term product support. The AVX brand carries recognition for manufacturing quality in the capacitor segment, which influences specification decisions when reliability and consistent electrical performance matter for the end application. For engineers choosing between competing part numbers, factors such as exact capacitance value, voltage rating, and temperature stability—all tied to specific part suffixes within a manufacturer's numbering scheme—would drive the decision toward this particular variant. Designers working on retrofit or replacement scenarios also benefit from the standardized nature of 1206 capacitors, as this package is documented across numerous reference designs and existing bill-of-materials archives. Whether supporting new product development or maintaining and updating legacy systems, this part represents a reliable solution within the broader landscape of general-purpose industrial capacitors.
