1210GC181KAT1A

The 1210GC181KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading producers of passive electronic components. This component belongs to the 1210 package family, which refers to its physical dimensions in metric notation (12.0mm × 10.0mm), making it a relatively compact surface-mount device suitable for modern PCB assembly processes. Multilayer ceramic capacitors like this part are fundamental building blocks in electronic circuits, used to store electrical energy, filter signals, couple or decouple AC signals, and stabilize power supplies. The ceramic dielectric material provides stable capacitance across a range of operating conditions, making MLCCs reliable choices for both consumer and industrial applications. The "GC" designation in AVX's product line typically indicates this capacitor operates with X7R or similar temperature-compensated ceramic material, which offers relatively stable capacitance performance across temperature variations. This characteristic makes it well-suited for applications where thermal stability is important, such as in automotive electronics, industrial control systems, power management circuits, and telecommunications equipment. The 1210 case size represents a middle ground in the MLCC world—larger than smaller packages like 0603 or 0805, but more compact than larger formats. This sizing allows engineers to achieve reasonable capacitance values while maintaining efficient use of PCB real estate. The surface-mount configuration enables automated assembly, reducing manufacturing costs and assembly time compared to through-hole alternatives. Engineers typically specify this exact part when they need a capacitor with the specific capacitance value encoded in the part number, combined with AVX's quality standards and reliable supply chain. The 1210 package is particularly common in applications requiring moderate to higher capacitance values—situations where smaller packages would be impractical, but where the largest MLCC formats are unnecessary. Common application areas include power supply filtering, signal coupling in audio circuits, bypass capacitors in digital logic circuits, and timing networks. The choice of AVX as a manufacturer often reflects design requirements around component reliability, temperature performance consistency, and adherence to industry standards. AVX MLCCs are widely specified in aerospace, medical device, and automotive applications where component traceability and consistent performance are critical. For specific electrical parameters including exact capacitance value, voltage rating, tolerance, and temperature coefficient for this part number, consultation of the detailed component specification documentation is recommended.
