1206YA821JAT2A

The 1206YA821JAT2A is a ceramic capacitor manufactured by AVX, one of the leading suppliers of passive components to the electronics industry. This component is housed in a 1206 surface-mount package, a standard form factor widely used in modern PCB assembly processes. The 1206 package provides a good balance between compact size and ease of handling during manufacturing, making it suitable for both manual rework and automated assembly environments. Ceramic capacitors in the 1206 package are fundamental building blocks in contemporary electronic design, serving critical roles in filtering, decoupling, timing, and energy storage applications across diverse industries. They are commonly found in power supply circuits, audio equipment, telecommunications infrastructure, automotive electronics, industrial control systems, and consumer electronics. The compact footprint makes them ideal for space-constrained designs where real estate on the PCB is at a premium. AVX's ceramic capacitor lines are recognized for consistent performance and reliability in demanding applications. The 1206 form factor strikes an important balance for engineers: it is significantly smaller than through-hole components, yet large enough to provide reasonable capacitance values and voltage ratings without excessive cost. This makes the 1206 package a practical choice for mainstream industrial and commercial products where reliability and manufacturability are important considerations. Engineers typically specify ceramic capacitors from established manufacturers like AVX when they require predictable performance, traceability, and compliance with industry standards. AVX components generally meet or exceed specifications relevant to automotive, medical device, aerospace, and industrial applications, depending on the specific product line. The 1206 package itself is well-established in design tools, footprint libraries, and supply chains, reducing integration risk. The exact electrical characteristics and ratings for this particular part number—including capacitance value, voltage rating, temperature coefficient, and tolerance—are determined by the specific designation within AVX's product family. Engineers selecting this component would consult technical documentation to confirm that the electrical and thermal specifications align with their circuit requirements, such as operating temperature range, voltage stress levels, and frequency response needs. For procurement, the established 1206 package ensures broad manufacturing support and multiple qualified suppliers, which can be important for long-term program sustainability and supply chain flexibility. Whether specified for filtering high-frequency noise, decoupling power supplies, or timing applications, the 1206 ceramic capacitor remains a reliable choice in professional electronic design.
