08055A561J4T2A

The AVX 08055A561J4T2A is a thin-film chip capacitor designed for precision applications requiring stable capacitance values and tight tolerance specifications. This component belongs to AVX's established family of 0805 surface-mount capacitors, which are widely used in industrial electronics, instrumentation, and precision signal conditioning circuits where reliability and consistency are paramount. Thin-film capacitors like this part offer superior performance compared to standard ceramic alternatives in applications demanding low distortion, low drift, and predictable electrical behavior across operating conditions. The 0805 package format—measuring approximately 2.0mm by 1.25mm—provides a compact footprint suitable for dense PCB layouts while remaining easy to handle and place with standard automated assembly equipment. This standardized package size ensures compatibility with most industrial manufacturing processes. The "561J" designation in the part number indicates the capacitance value and tolerance band for this device. Thin-film capacitors in this series are commonly specified in filtering applications, including power supply decoupling, AC coupling, and EMI suppression circuits where the stability of the capacitance value is critical to circuit performance. Engineers often choose thin-film construction when working with precision analog circuits, medical instrumentation, aerospace systems, or any application where capacitance drift or non-linearity could compromise system accuracy. The 2A suffix typically indicates RoHS compliance and lead-free construction, which is standard for modern industrial applications and ensures compliance with environmental regulations required by OEMs serving global markets. AVX's manufacturing standards for thin-film capacitors emphasize consistent quality and long-term reliability, making them suitable for mission-critical deployments and applications requiring extended operational life. Engineers select this specific part number when the application demands the particular capacitance value paired with the reliability characteristics of AVX's thin-film technology. Common reasons for specifying this exact component include the need for precise tolerance matching in analog filter networks, requirement for stable performance in temperature-variable environments, or system designs where capacitor aging must be minimized over the product's intended lifespan. This part is compatible with lead-free solder reflow processes and standard PCB assembly workflows common in industrial manufacturing. Its small size and established performance history make it a practical choice for design engineers updating legacy systems or developing new equipment where proven component reliability reduces development risk.
