1812AA182KAT1A

The 1812AA182KAT1A is a multilayer ceramic capacitor manufactured by AVX, one of the industry's established suppliers of passive components. This part number indicates a capacitor in the 1812 package size, which refers to the physical dimensions of 0.180 x 0.120 inches. This standardized surface-mount package is widely used in modern electronics where space efficiency is important but components need to maintain reasonable handling and soldering characteristics. Multilayer ceramic capacitors (MLCCs) like this model are fundamental building blocks in electronics design, serving functions such as decoupling, filtering, energy storage, and signal coupling across countless applications. The 1812 package strikes a practical balance, offering higher capacitance values than smaller packages while remaining compact enough for densely populated circuit boards. AVX's ceramic capacitor lines are recognized for consistent quality and reliable performance in both commercial and industrial environments. The "AA" designation in this part number indicates this is a general-purpose capacitor within AVX's product family, suitable for applications that don't require specialized performance characteristics like high voltage, extreme temperature stability, or piezoelectric suppression features. This makes it an economical choice for mainstream applications where standard performance meets design requirements. Engineers typically specify capacitors from established manufacturers like AVX when reliability and availability are priorities in production environments. Choosing a recognized part number ensures consistent performance across manufacturing runs, easier replacement of components during repair, and broader availability through distribution channels. For industrial applications, equipment manufacturers, and contract electronics assemblers, having access to well-documented, widely stocked components reduces design risk and supply chain complexity. The 1812 package size is frequently found in power supply circuits, audio equipment, telecommunications infrastructure, automotive electronics, and industrial control systems. Its versatility makes it suitable for applications operating at moderate voltage and frequency ranges in stable thermal environments. When selecting between capacitor alternatives, engineers consider package size constraints, required capacitance value, voltage rating, temperature coefficients, and long-term reliability data. The 1812AA182KAT1A's availability from a major manufacturer provides confidence in consistent electrical performance and mechanical reliability, making it a dependable choice for production designs where component consistency matters. For designers working with established platforms or replacement applications, this part number offers proven compatibility and straightforward sourcing.
