1812AA200KAT1A

The 1812AA200KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established suppliers of passive electronic components. This capacitor is housed in an 1812 package format, which represents a surface-mount component measuring approximately 0.18 by 0.12 inches (4.5 by 3.2 millimeters). This mid-sized package is commonly used in applications where designers need to balance capacitance value, voltage rating, and board space constraints. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronics, serving critical roles in power supply filtering, signal coupling, decoupling, and timing circuits across a broad range of industrial and commercial equipment. The 1812 footprint is particularly popular in medium-power applications and general-purpose circuit design where engineers require reliable performance without excessive board real estate consumption. The "AA" designation in this part number typically indicates the capacitor's dielectric material class, which affects its temperature stability, capacitance retention, and frequency response characteristics. Capacitors in this family are generally suited for applications requiring stable performance across commercial to industrial temperature ranges. The "200K" notation in the part number relates to the capacitor's rated voltage and capacitance value designation within AVX's naming convention. Engineers typically specify AVX ceramic capacitors for applications where component reliability, consistent performance, and proven manufacturability are important considerations. AVX's ceramic capacitor lines are widely used in telecommunications equipment, automotive electronics, industrial control systems, power management circuits, and consumer electronics where quality and longevity matter. The 1812 package format offers practical advantages for production environments. It provides excellent solder joint reliability, allows for automated pick-and-place assembly, and delivers predictable electrical performance. The surface-mount configuration makes this component ideal for modern PCB designs where through-hole mounting is either impractical or undesirable. When selecting capacitors for specific circuit functions, engineers consider factors including working voltage, capacitance tolerance, temperature coefficient, and ESR (equivalent series resistance). The 1812AA200KAT1A fits into a well-established product family where these parameters are optimized for general industrial and commercial applications requiring dependable energy storage and signal conditioning. This component represents a standard solution for designers who need a proven multilayer ceramic capacitor with established supply chain support and consistent electrical performance characteristics across production batches.
