12103C104KAT2A

The AVX 12103C104KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose energy storage and filtering applications across a wide range of electronic equipment. This component is part of the established 1210 package family, which represents a common surface-mount footprint measuring 12.7mm by 10.2mm, making it suitable for space-conscious PCB layouts while offering reasonable capacitive performance. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronics, serving critical roles in power supply filtering, decoupling, signal coupling, and noise suppression throughout industrial and commercial applications. The 1210 case size provides a middle ground between smaller 0805 and 0603 packages and larger formats, allowing designers to achieve moderate capacitance values without excessive board real estate consumption. AVX is a well-established manufacturer known for producing reliable ceramic capacitors across numerous market segments. Their MLCC products are widely specified in industrial control systems, telecommunications equipment, consumer electronics, automotive applications, and medical devices where proven performance and consistent quality are essential requirements. Engineers typically select the 12103C104KAT2A when they need a dependable, standard-value ceramic capacitor in a compact surface-mount package for mainstream applications. The part designation follows standard AVX naming conventions, with the numerical portion indicating its physical dimensions and electrical characteristics. This component would be chosen in situations where cost-effectiveness and proven reliability are prioritized, and where the performance characteristics of ceramic dielectric technology meet the circuit requirements. Common reasons to specify this exact part include design continuity with existing products, established supplier relationships, proven performance history in production environments, and the extensive availability of this standard component across the distribution channel. The 1210 package format also provides good solderability and mechanical robustness on production assembly lines, reducing manufacturing risk compared to smaller alternatives. The ceramic dielectric chemistry used in AVX MLCCs generally offers stable performance across commercial temperature ranges, making these capacitors suitable for both indoor industrial environments and controlled manufacturing applications. Their relatively low equivalent series resistance and inductance make them effective at high-frequency filtering and decoupling tasks. For engineers working on product designs, refresh cycles, or manufacturing optimization, this part represents a mature, well-documented choice that simplifies qualification, reduces design risk, and ensures straightforward sourcing throughout the product lifecycle. The 1210 package format remains relevant in modern equipment despite advances in smaller alternatives, particularly where reliable performance and manufacturing ease are valued.
