08053C121KAT2A

The AVX 08053C121KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and signal coupling applications across a wide range of industrial and commercial electronics. This component represents the type of capacitor found in virtually every modern electronic device, from power supplies and audio equipment to telecommunications infrastructure and industrial control systems. Multilayer ceramic capacitors like this part are constructed using alternating layers of ceramic dielectric material and metal electrodes, which are then stacked and sintered into a single monolithic package. This construction method allows manufacturers to achieve high capacitance values in physically small packages while maintaining stable performance across various operating conditions. The 0805 designation in the part number refers to the imperial package size (approximately 2.0mm × 1.25mm), making it suitable for both through-hole and surface-mount assembly processes, depending on your manufacturing workflow. The "121" designation indicates a capacitance value within the standard industrial range. Capacitors in this general family are typically specified for applications requiring reliable energy storage, AC coupling between circuit stages, power supply filtering, and electromagnetic interference suppression. Engineers commonly choose ceramic capacitors for these roles because they offer excellent frequency response characteristics, low equivalent series resistance (ESR), and compact form factors that help minimize PCB real estate. AVX is a well-established manufacturer known for producing high-reliability passive components used in demanding industrial environments. Components from their standard ceramic capacitor portfolio are specified in applications where consistent performance, long-term stability, and cost-effectiveness are important considerations. The 08053C series reflects a commitment to providing components that meet the electrical and mechanical requirements of modern manufacturing standards. When selecting this specific part number versus alternatives, engineers typically consider package compatibility with existing PCB layouts, the need for proven supplier reliability, and the electrical characteristics required for their particular circuit design. The 0805 package size offers a practical balance between component density and ease of handling during assembly and rework operations. This capacitor would be appropriate for designers working on industrial automation systems, embedded control electronics, power conditioning circuits, and other applications where stable, long-life performance is essential. The ceramic dielectric material provides good voltage handling characteristics and temperature stability suitable for industrial environments.
