12061A391FAT2A

The 12061A391FAT2A is a thin-film capacitor manufactured by AVX, a recognized producer of passive electronic components for demanding industrial and aerospace applications. This component belongs to the 1206 package family, which represents one of the most widely adopted surface-mount capacitor formats in modern electronics manufacturing. Thin-film capacitors are precision components designed to deliver stable capacitance values with exceptionally low tolerance ranges and minimal drift over temperature and time. Unlike their ceramic or electrolytic counterparts, thin-film units achieve this stability through vacuum-deposited metal layers on a polymer substrate, making them ideal for applications where consistency and reliability are non-negotiable. The 1206 package size—measuring approximately 3.2mm by 1.6mm—allows for high-density PCB layouts while remaining large enough to handle reasonable power dissipation for most signal-level applications. AVX thin-film capacitors in the 1206 format are commonly specified in precision analog circuits, filtering networks, timing applications, and test instrumentation where capacitance accuracy directly impacts system performance. Engineers frequently select thin-film capacitors for AC coupling, biasing networks, and frequency-dependent circuits in audio and RF applications due to their low dielectric absorption and excellent frequency response characteristics. The technology also provides superior voltage linearity compared to ceramic alternatives, which is critical in precision measurement systems and signal conditioning circuits. This part number designation suggests a specific capacitance value and voltage rating within AVX's thin-film 1206 portfolio. The suffix structure typical of AVX components indicates particular performance characteristics, though the exact electrical specifications should be verified against the component's technical documentation to ensure proper circuit integration. Engineers considering the 12061A391FAT2A would typically evaluate it against other thin-film options or high-stability ceramic alternatives when their application demands predictable performance across operating temperature ranges, extended service life without capacitance degradation, or compliance with military and aerospace reliability standards. The 1206 package size balances component cost against performance, making it economical for production volumes while maintaining the precision characteristics that justify thin-film technology selection. For integration into industrial control systems, medical instrumentation, aerospace electronics, or precision measurement devices, thin-film capacitors provide the long-term stability and performance consistency that justifies their specification despite higher unit costs compared to standard ceramic alternatives. This component represents a proven choice for engineers who prioritize reliability and predictable performance in applications where capacitor aging or tolerance drift could compromise system functionality.
