1812SA470KAT1A

The 1812SA470KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established capacitor producers. This component belongs to the 1812 package family, which refers to its physical dimensions in the metric system (approximately 4.5mm × 3.2mm × 2.5mm). The 1812 form factor is a standard surface-mount package widely used in modern electronics where moderate capacitance values and compact board real estate are required. The "SA" designation in this part number indicates the capacitor is part of AVX's general-purpose MLCC series, typically designed for applications requiring stable performance across a range of industrial and consumer electronics environments. These capacitors use ceramic dielectric material, which provides good reliability and consistent electrical characteristics suitable for many circuit applications. MLLCs in the 1812 package size serve multiple functions in electronic systems. They are commonly employed for decoupling and bypassing applications, where they help filter noise and stabilize power supply voltages near integrated circuits and other active components. They also appear in timing circuits, filtering stages, and coupling applications where their compact size and reasonable capacitance density offer practical advantages over larger alternative packages. Engineers typically specify MLLCs from established manufacturers like AVX when they need reliable components with consistent quality across production runs. AVX's reputation for manufacturing standards means designers can depend on stable electrical performance and predictable aging characteristics over the component's operational life. The 1812 package specifically appeals to engineers designing space-constrained assemblies, such as portable equipment, automotive electronics, industrial control modules, and telecommunications infrastructure, where every millimeter of board space matters. The choice of this particular part over alternatives often comes down to matching capacitance value, voltage rating, and temperature stability requirements to specific circuit needs. The ceramic material provides good frequency response characteristics, making these capacitors suitable for both DC bias and AC signal filtering applications across audio, RF, and power distribution circuits. When integrating this component into designs, engineers appreciate the standardization of the 1812 package—it is widely supported by PCB layout tools, assembly equipment, and multiple sourcing options across the component supply chain. This standardization reduces design risk and manufacturing complexity compared to less common package formats.
