1812AA470KAT1A

The AVX 1812AA470KAT1A is a multilayer ceramic capacitor (MLCC) in the 1812 surface-mount package format. This component belongs to the general-purpose capacitor category and is designed for use in a wide range of electronic circuits requiring stable capacitance and reliable performance across standard operating conditions. Multilayer ceramic capacitors like this model are fundamental passive components found in virtually every modern electronic device and industrial system. They serve critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and high-frequency applications. The 1812 package designation indicates the physical dimensions (0.18 inches by 0.12 inches, or approximately 4.5mm by 3.2mm), making it a mid-sized surface-mount capacitor suitable for compact circuit board designs while remaining large enough to handle moderate power levels. The AVX 1812AA series represents a robust line of capacitors commonly specified in industrial control systems, power electronics, telecommunications equipment, automotive applications, and consumer electronics. These capacitors are engineered to provide consistent performance in demanding environments where reliability and longevity are essential. The ceramic dielectric material used in this construction offers excellent stability over time and good performance at various frequencies, making them particularly valuable in both DC and AC applications. Engineers typically choose the 1812 package size when they need to balance component density with electrical performance. Compared to smaller packages, the 1812 offers improved voltage handling and capacitance range options. Compared to larger packages, it occupies significantly less board space, allowing for more efficient circuit layouts in space-constrained designs. This size sweet spot makes it a popular choice in mixed-signal circuits, power distribution networks, and precision analog applications. The AVX brand reputation for quality and consistency makes this part number attractive when specification stability across production runs is important. Engineers may select this particular component when they require a well-established, proven design that meets established reliability standards and has demonstrated performance history in similar applications. Typical reasons for specifying this exact part include the need for a mid-range surface-mount ceramic capacitor with proven field reliability, the requirement for standard industrial-grade performance characteristics, or as a replacement component in established designs. The combination of package size, manufacturer reputation, and compatibility with standard pick-and-place manufacturing processes makes this a practical choice for both prototype development and high-volume production scenarios.
