0805YA220JAT2A

The 0805YA220JAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the established suppliers of passive electronic components. This part is housed in the 0805 surface-mount package, a widely adopted industry standard that measures approximately 2.0mm x 1.25mm, making it suitable for high-density PCB designs where space efficiency is critical. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, used to store and release electrical energy, filter noise, couple signals, and stabilize power supplies across countless applications. The 0805 package strikes a practical balance between miniaturization and ease of handling, remaining popular in both automated assembly environments and manual rework scenarios. The "YA" designation in this part number indicates the capacitor belongs to AVX's general-purpose ceramic capacitor family, typically designed for standard commercial and industrial applications rather than specialized high-reliability or high-temperature segments. Capacitors in this category are commonly found in consumer electronics, industrial control equipment, telecommunications infrastructure, automotive systems, and general-purpose industrial instrumentation. The "220J" notation suggests this component has a nominal capacitance value of 22nF (0.022µF) with a J-grade tolerance, which typically indicates a tolerance band standard for general-purpose applications. This capacitance value positions it in the range suitable for decoupling power supply pins, AC coupling in signal paths, filtering applications, and timing circuits in digital and analog designs. AVX's MLCC products are manufactured using multiple layers of ceramic dielectric material with interleaved metallic electrodes, a construction method that provides good performance across temperature ranges and frequency spectrums typical of industrial use. The surface-mount termination allows for direct soldering to modern PCB substrates using standard reflow or wave-soldering processes. Engineers might select the 0805YA220JAT2A specifically when they require a reliable, compact ceramic capacitor with proven manufacturing consistency from an established supplier. The 0805 package offers advantages over smaller alternatives (0603, 0402) when component availability, thermal performance, or manual inspection considerations come into play, while remaining more cost-effective and easier to handle than larger packages. This part is particularly suitable for applications where component height is constrained but miniaturization is still important, and where the general-purpose performance characteristics of commercial-grade ceramics adequately meet design requirements.
