12065C202KAT2A

# Product Description The 12065C202KAT2A is a multilayer ceramic capacitor manufactured by AVX, one of the industry's established suppliers of passive components. This part belongs to the general category of fixed capacitors and is designed to serve filtering, decoupling, and energy storage functions in electronic circuits across industrial and commercial applications. Multilayer ceramic capacitors (MLCCs) like this component are among the most widely used capacitor types in modern electronics due to their small form factor, reliability, and cost-effectiveness. They consist of multiple layers of ceramic dielectric material with alternating metallic electrodes, allowing engineers to achieve relatively high capacitance values in compact packages. The 12065C202KAT2A uses a 1206 surface-mount package, which is a standard footprint approximately 3.2mm × 1.6mm in length and width. This size is ideal for densely populated circuit boards where space efficiency is critical without sacrificing performance. The "202" designation in the part number typically relates to the capacitance value, though exact specifications should be verified against the component datasheet or technical documentation. AVX's capacitor series featuring this package type are commonly found in power supply circuits, where they handle bulk capacitance and transient filtering requirements. They are also frequently specified in signal integrity applications, digital logic boards, telecommunications equipment, and industrial control systems where stable voltage references and noise suppression are essential. Engineers choose this specific part number for several reasons. The 1206 package offers a good balance between component size and current-handling capability compared to smaller packages, making it suitable for applications requiring moderate capacitance with reasonable ripple current ratings. AVX's manufacturing standards ensure consistent quality and long-term reliability in harsh industrial environments. The surface-mount design enables automated assembly, reducing manufacturing costs and assembly time compared to through-hole alternatives. The ceramic dielectric material in MLCCs like this part provides stable performance across a wide temperature range typical of industrial applications. Depending on the specific dielectric class, these capacitors may exhibit predictable capacitance behavior or slightly voltage-dependent characteristics—factors engineers must consider during circuit design. When selecting the 12065C202KAT2A, engineers should review the complete technical specifications, including capacitance tolerance, voltage rating, equivalent series resistance, and temperature coefficient. This ensures the part meets the exact requirements of the target application, particularly in circuits where precision, reliability, and performance stability are non-negotiable.
