08055A4R7CAT2A

The AVX 08055A4R7CAT2A is a thin-film chip capacitor designed for precision applications requiring stable capacitance and low parasitic effects. This component belongs to the 0805 surface-mount package family, which represents a standard intermediate size widely used in compact electronic assemblies where space efficiency matters but component accessibility remains practical for manufacturing and rework. Thin-film capacitors are constructed using vacuum-deposited metal oxide or ceramic dielectric layers, which provide superior performance characteristics compared to conventional thick-film alternatives. This manufacturing approach delivers excellent frequency stability, predictable temperature coefficients, and minimal distortion, making thin-film capacitors the preferred choice in signal conditioning, precision analog circuits, and high-frequency applications where performance consistency is non-negotiable. The "4R7" designation in this part number indicates a capacitance value in the mid-range of typical thin-film offerings. Engineers commonly specify capacitors in this range for coupling and bypass applications, AC signal filtering, and impedance matching networks. The specific tolerance and voltage rating built into this part number variant make it suitable for applications demanding tight capacitance control and reliable long-term performance. Thin-film capacitors excel in environments where temperature stability and aging characteristics significantly impact circuit performance. Unlike electrolytic or conventional ceramic capacitors, thin-film designs exhibit minimal capacitance drift over temperature extremes and operational life, a critical advantage in precision instrumentation, medical devices, aerospace electronics, and military equipment where recalibration or component replacement presents logistical or safety challenges. The 0805 package format strikes an effective balance for modern industrial design. It offers sufficient size for reliable solder joint formation using standard reflow processes while maintaining compact board-level density. This package is compatible with automated assembly equipment and hand-rework procedures, reducing manufacturing costs while supporting both high-volume production and limited-quantity specialized builds. Engineers select this specific AVX part when design specifications call for demonstrated reliability, predictable electrical behavior across operating conditions, and long-term performance stability that justifies the higher cost relative to standard ceramic alternatives. Applications include precision test and measurement equipment, professional audio systems, telecommunications infrastructure, industrial control electronics, and sensor signal conditioning circuits where the superior stability of thin-film technology directly enhances overall system accuracy and dependability. The AVX manufacturing heritage and reputation for quality assurance make this component suitable for applications requiring traceability, documented reliability, and compliance with industrial standards where component provenance and consistent performance characteristics are design requirements.
