12061A221MAT4A

The AVX 12061A221MAT4A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and signal coupling applications in electronic equipment and industrial systems. As a surface-mount component in the 1206 package format, this capacitor offers a compact footprint suitable for modern PCB designs where space efficiency is important while maintaining reliable performance. MLCCs are fundamental passive components used across virtually all electronic applications, from consumer devices to industrial control systems, telecommunications equipment, and automotive electronics. The 1206 package size represents a standard industry format that provides a practical balance between component density and handling characteristics for both automated assembly and manual rework processes. This particular part is suited for applications requiring a moderate capacitance value in a dependable ceramic dielectric construction. The AVX product line of multilayer ceramic capacitors is widely recognized in the electronics industry for consistent quality and reliable performance across commercial and industrial temperature ranges. AVX manufactures these components using established processes that deliver stable capacitance characteristics and predictable electrical behavior over the component's operational life. The ceramic dielectric material provides excellent frequency response, making these capacitors effective for high-frequency filtering applications where traditional electrolytic alternatives may not be suitable. Engineers typically specify this component when designing power supply circuits, signal conditioning networks, or general decoupling applications where the stability and compact size of an MLCC provide clear advantages. The 1206 package strikes a practical middle ground—offering better capacitance density than larger packages while remaining easier to work with in manufacturing and repair compared to smaller 0603 or 0402 formats. The multilayer ceramic construction ensures minimal equivalent series resistance (ESR) in most operating conditions, supporting effective noise suppression and voltage regulation tasks. This part would be selected over alternatives when a designer needs reliable, temperature-stable capacitance in a standard package format without space constraints that would demand ultra-miniature components. The AVX manufacturing standard typically ensures broad compatibility across supply chains and consistent availability, reducing procurement complexity for equipment manufacturers and system integrators managing component inventories. Applications include industrial automation equipment, power management modules, data acquisition systems, and general electronic assemblies where dependable capacitive filtering is required without specialized performance demands that would necessitate film, tantalum, or specialty capacitor technologies.
