1812AA471KAT1A

The 1812AA471KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components. This part belongs to the 1812 package family, which refers to its physical dimensions in metric notation (approximately 4.5mm × 3.2mm × 1.6mm), making it suitable for surface-mount applications on printed circuit boards. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, widely used for energy storage, filtering, decoupling, and signal coupling across numerous applications. The 1812 package size represents a mid-range form factor that balances capacitive performance with board space efficiency, making it a popular choice in designs where compact footprint matters but volume requirements are moderate. AVX's 1812 series capacitors are engineered for reliability in demanding industrial and commercial environments. These components are commonly found in power supply circuits, where they provide bulk capacitance and high-frequency noise filtering. They're also extensively used in audio equipment, telecommunications infrastructure, automotive electronics, medical devices, and general-purpose industrial control systems. The 1812 package's robustness and established manufacturing processes make it a dependable choice for applications requiring long-term stability and consistent performance. Engineers typically specify AVX MLCCs in the 1812 package when they need a cost-effective capacitor solution that doesn't require the size constraints of smaller packages like 0805 or 0603, yet doesn't demand the higher capacitance density or specialized performance of larger packages. This part number's configuration makes it suitable for mainstream industrial applications where performance requirements are well-established and component reliability data is extensive. The 1812 package format also simplifies assembly and rework in manufacturing environments. Its size allows for reliable solder joint formation and accommodates standard pick-and-place equipment used in high-volume production. For maintenance and repair operations, the 1812 package remains accessible and straightforward to replace compared to smaller form factors. AVX has a strong reputation for consistent quality in ceramic capacitor manufacturing, with rigorous process controls that support applications requiring high reliability. Engineers choosing this specific part number can rely on the established track record of the 1812 package family and AVX's manufacturing standards, making it a pragmatic selection for designs where performance margins are well-understood and long-term supply stability is important.
