08055A120JAT2A

The AVX 08055A120JAT2A is a multilayer ceramic capacitor (MLCC) in the compact 0805 surface-mount package format. This component is designed for general-purpose energy storage, filtering, and decoupling applications across a wide range of electronic systems and industrial equipment. Multilayer ceramic capacitors are fundamental passive components used in virtually every modern electronic device. The 0805 package represents one of the most widely standardized sizes in the industry, measuring approximately 2.0mm x 1.25mm, making it suitable for high-density PCB layouts while remaining easy to handle and place with standard automated assembly equipment. This size sits between smaller 0603 packages and larger 1206 packages, offering a practical balance between board space efficiency and capacitance rating capability. The "A" designation in the part number indicates this capacitor uses an X7R dielectric material, which is a temperature-stable ceramic composition. X7R capacitors maintain relatively stable capacitance across operating temperature ranges, typically performing well in both consumer and industrial temperature environments. This makes them ideal for applications where temperature compensation is not critical but stable performance across varying conditions is important. This part is commonly specified in power supply circuits, signal filtering networks, high-frequency decoupling, and general circuit smoothing applications. Engineers often choose AVX MLCCs for demanding industrial and automotive environments due to the manufacturer's reputation for consistent quality and reliable performance under stringent operating conditions. The compact 0805 format allows designers to implement multi-layer decoupling strategies on modern PCBs without consuming excessive real estate. The multilayer construction of this capacitor provides excellent high-frequency characteristics compared to older film or electrolytic alternatives, making it particularly valuable in applications involving digital logic, RF circuits, and switching power supplies. The small parasitic inductance inherent to the surface-mount format contributes to effective noise suppression at higher frequencies. Engineers typically specify this exact part number when they require a proven, standard AVX MLCC in 0805 format as a direct replacement in existing designs, for supply chain continuity, or when the specific electrical characteristics of the 08055A120JAT2A match their circuit requirements. The prevalence of this part number in industry-standard designs and its availability through multiple distribution channels make it a practical choice for both prototype and production volume applications.
