1206SC821KAT1A

The 1206SC821KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established capacitor producers. This component uses the widely recognized 1206 surface-mount package, which measures approximately 3.2mm by 1.6mm, making it suitable for automated pick-and-place assembly on printed circuit boards where space efficiency and production scalability are important. MLCCs like this part are fundamental passive components found across virtually every modern electronic device and industrial system. They serve critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and energy storage in various circuit topologies. The 1206 package size represents a common middle ground in the capacitor landscape—larger than 0603 or 0402 packages but smaller than 1812 or larger formats—offering a practical balance between board space constraints and the handling requirements of modern manufacturing equipment. The "821" designation in this part number indicates a capacitance value in the picofarad range, consistent with AVX's standard naming conventions. This capacitance value is typical for applications requiring relatively low-capacitance filtering, such as high-frequency signal integrity circuits, RF applications, or decoupling for fast-switching digital logic where precise, low-inductance filtering is needed. AVX's 1206 MLCC portfolio is generally characterized by reliable performance across automotive, industrial, telecommunications, and consumer electronics segments. These capacitors are designed to meet established industry standards and typically feature stable performance across specified operating temperature ranges, making them suitable for both commercial and demanding industrial environments. Engineers might specify this exact part number when they require a proven, widely-available capacitor in the 1206 package with this specific capacitance value. AVX's reputation for quality and the extensive use of 1206 MLCCs throughout the industry mean that this component offers excellent availability, consistent manufacturing quality, and straightforward sourcing for volume production. Additionally, the standardized 1206 package ensures compatibility with existing assembly processes and PCB layouts, reducing design risk and simplifying supply chain management. For applications requiring precise electrical performance or operating in extreme conditions, engineers should verify the specific electrical ratings, temperature coefficients, and frequency characteristics against detailed component specifications. The 1206 package is also suitable for both prototype and high-volume production environments, making it a versatile choice across the development lifecycle.
