1812HC471MAT3A

The 1812HC471MAT3A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, representing a widely used passive component in modern electronic equipment. This capacitor employs a 1812 case size, a standard metric package format that measures 4.5mm x 3.2mm, making it suitable for space-constrained surface-mount applications while providing reasonable capacitance density. Multilayer ceramic capacitors like this model are fundamental building blocks in electronics design, serving critical functions in power supply circuits, signal coupling and decoupling, filtering, and noise suppression. The HC designation in this part number indicates this capacitor belongs to AVX's general-purpose ceramic capacitor family, designed for mainstream industrial and commercial applications rather than specialized high-reliability or military-grade environments. The 1812 package size positions this component in a mid-range segment—larger than compact 0603 or 0805 packages but smaller than bulkier 2220 or 1825 formats. This size offers engineers a practical balance between board space efficiency and handling capability during manufacturing. Surface-mount technology makes these capacitors compatible with automated pick-and-place assembly, reducing labor costs and improving production consistency for medium to high-volume manufacturing runs. Engineers typically specify this exact part when design requirements call for a standard ceramic capacitor in the 1812 footprint without specialized performance demands. Common reasons for choosing this specific component include board redesign compatibility with existing layouts, standardization initiatives within a company's component library, or when standard lead times and broad availability are prioritized over premium alternatives. The 1812 package also provides better tolerance and temperature stability characteristics compared to smaller packages, which can be important in precision analog circuits or systems operating across varied environmental conditions. This capacitor type is extensively found in consumer electronics, industrial control systems, telecommunications equipment, automotive electronics, and computing devices. Applications range from bulk energy storage near power delivery networks to high-frequency signal coupling in RF stages, depending on the specific capacitance and voltage rating selected for the design. For engineers evaluating alternatives, the 1812 package offers a middle ground in the ceramic capacitor selection process. Smaller packages reduce board area but may sacrifice some performance margins; larger packages provide enhanced ratings but consume more PCB real estate. The AVX HC series' reputation for consistency and availability makes it a reliable choice for designers seeking predictable supply chains and proven performance in standard operating conditions.
