1808HA820MAT1A

# Product Description The 1808HA820MAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for use in demanding industrial and commercial electronic applications. This component belongs to the High-Voltage A (HA) series within AVX's extensive capacitor portfolio, and is housed in a compact 1808 surface-mount package format that balances size constraints with electrical performance requirements. Multilayer ceramic capacitors like this part serve as fundamental energy storage and filtering elements across countless circuit topologies. They are commonly specified in power supply designs, signal conditioning circuits, RF applications, and filtering stages where stable capacitance and reliable performance are essential. The HA series designation indicates this capacitor is engineered for higher voltage applications, making it suitable for circuits operating well above standard low-voltage thresholds. The 1808 case size represents a mid-range surface-mount package that offers practical advantages in modern PCB assembly. This footprint allows designers to achieve reasonable component density while maintaining adequate pad spacing for automated manufacturing processes. The package is compatible with standard reflow soldering equipment used in both contract manufacturers and in-house assembly operations, which contributes to this part's widespread adoption across industrial equipment manufacturers. AVX's HA series capacitors are known for their stability across temperature ranges and frequency response characteristics typical of ceramic dielectric technology. Engineers often select parts from this family when designs require capacitors that maintain consistent performance in thermally variable environments common to industrial control systems, automotive electronics, and equipment operating in harsh conditions. The specific part number designation, including the "820" value within the nomenclature, identifies this as a particular capacitance value within AVX's standardized product range. Engineers evaluating this exact part typically do so after determining their circuit requires this specific capacitance rating combined with the voltage rating inherent to the HA series classification. When sourcing the 1808HA820MAT1A, engineers value the established reliability history of AVX components, the predictable sourcing availability of mainstream catalog parts, and compatibility with existing manufacturing processes. This capacitor would be chosen over alternatives when a design specifically calls for the performance characteristics, size constraints, and voltage specifications represented by this particular part number. The 1808 package remains a standard offering across multiple manufacturers, though the HA series represents AVX's particular implementation of this capacitor class, with associated quality and performance characteristics specific to AVX's manufacturing processes.
