1812SA820KAT1A

The 1812SA820KAT1A is a surface-mount ceramic capacitor manufactured by AVX, representing a key component in the 1812 package family. This part number designation indicates a capacitor in the 1812 physical size format, which measures approximately 4.5mm x 3.2mm, making it suitable for compact circuit board layouts where space efficiency is important without requiring the smallest available package footprints. Ceramic capacitors in the 1812 package are widely used across industrial electronics, telecommunications equipment, automotive systems, and consumer electronics applications. Their relatively large surface area compared to smaller packages allows for higher capacitance values and voltage ratings in a reasonably compact form factor. This makes the 1812 package a practical choice in many designs where designers need to balance component density with manufacturing ease and thermal performance. The "SA" designation within AVX's product coding typically indicates this capacitor belongs to a general-purpose ceramic series optimized for standard industrial and commercial applications. Capacitors in this category serve numerous functions within electronic circuits, including power supply filtering, decoupling, coupling, timing, and signal conditioning. The versatility of ceramic capacitors means they appear in power distribution networks, audio circuits, RF applications, and DC-DC converter designs. AVX's ceramic capacitor products are engineered to meet demanding reliability requirements across temperature and voltage operating ranges typical of industrial environments. The 1812 package format offers several practical advantages: it provides adequate lead-to-pad spacing for reliable soldering during automated assembly, generates manageable thermal profiles during operation, and maintains stable electrical characteristics across typical operating conditions found in industrial equipment. An engineer might select the 1812SA820KAT1A specifically when the design requires a ceramic capacitor in this package size with characteristics suited to general-purpose filtering and decoupling roles. The 1812 format offers better capacitive density than smaller packages while remaining compatible with standard surface-mount assembly equipment and board design practices. When board real estate allows for this size, specifying the 1812 package can sometimes provide cost advantages and improved performance margins compared to smaller alternatives. For design engineers and procurement specialists, identifying the correct AVX ceramic capacitor model requires understanding both the physical package constraints of the target application and the electrical requirements the component must satisfy. The 1812SA series provides a reliable foundation for applications requiring stable, proven ceramic capacitor technology in mid-sized packages.
