12061A561KAT4A

The AVX 12061A561KAT4A is a thin-film capacitor belonging to the 1206 surface-mount package family, representing a compact, high-reliability component suitable for precision analog and RF applications. This component is manufactured by AVX, a recognized supplier of electronic capacitors for demanding industrial and aerospace environments. Thin-film capacitors in the 1206 package offer engineers a combination of small footprint and stable electrical performance, making them ideal for applications where board space is constrained but precision capacitance values are critical. The 1206 designation refers to the imperial dimensions of the component (0.126 × 0.063 inches), allowing for efficient automated assembly and integration into modern printed circuit boards. Components from this series are commonly specified in RF filtering, signal conditioning, impedance matching networks, and precision measurement instrumentation. Their thin-film construction provides superior frequency stability and lower distortion compared to conventional ceramic capacitors, making them particularly valuable in applications where signal integrity must be maintained across temperature variations and over extended operational lifetimes. The "561" designation embedded in the part number indicates a specific capacitance value in the pF or nF range depending on series conventions. Engineers often select AVX thin-film capacitors when tight tolerance requirements, predictable aging characteristics, or low equivalent series resistance (ESR) become design drivers. Applications include test and measurement equipment, communications infrastructure, medical diagnostic devices, and military electronics where performance consistency and reliability cannot be compromised. Thin-film capacitors manufactured by AVX typically demonstrate excellent temperature coefficients and minimal capacitance drift over time, which is essential in precision circuits requiring long-term stability. The surface-mount format allows for automated placement on production lines, reducing assembly costs and improving consistency in high-volume manufacturing scenarios. Engineers might specify this exact part number when design requirements call for documented traceability, when the application operates in harsh environments (high vibration, thermal cycling, or radiation exposure), or when existing qualified designs already employ AVX components. The consistent performance characteristics of AVX thin-film capacitors make them particularly attractive for military, aerospace, and medical device manufacturers where component qualification and documentation are essential. The 1206 package size also provides a practical balance between component density and handling ease during repair and rework operations, an important consideration for complex assemblies requiring field maintenance or engineering diagnostics.
