1812SC101KAT1A

The 1812SC101KAT1A is a multilayer ceramic capacitor manufactured by AVX, a well-established producer of passive components for industrial and commercial electronics. This part represents a mid-range solution in the surface-mount capacitor category, designed for applications requiring reliable energy storage, filtering, and signal coupling in compact form factors. The 1812 designation refers to the physical package size—measuring 1.8 millimeters by 1.2 millimeters—making it a standard SMD footprint widely used in modern PCB designs where space efficiency is important but component density is moderate. This size sits between smaller 0603 and 0805 packages and larger chip capacitors, offering a practical balance between handling ease, placement speed, and capacitive performance. As a multilayer ceramic capacitor (MLCC), this component uses alternating layers of ceramic dielectric material and metal electrodes to achieve its capacitive characteristics. The "SC" designation in the part number typically indicates a specific dielectric class and performance profile within AVX's product families, generally suited for general-purpose filtering, decoupling, and bypass applications across consumer, industrial, and telecommunications equipment. Engineers commonly specify AVX multilayer ceramic capacitors in this package for power supply decoupling on logic boards, analog signal conditioning circuits, RF filtering stages, and general noise suppression applications. The 1812 form factor provides adequate capacitive volume while remaining compatible with standard pick-and-place assembly processes, reducing manufacturing complexity compared to larger discrete components. This part class is particularly valued in applications where multiple capacitors must be distributed across a circuit board for localized filtering near IC power pins, as the compact footprint allows dense placement without creating board layout bottlenecks. Industrial control systems, embedded computing modules, and instrumentation frequently employ capacitors in this size and performance range. Choosing the 1812SC101KAT1A over alternatives typically depends on matching the specific capacitance value, voltage rating, and temperature stability requirements of the target circuit. AVX's reputation for consistent manufacturing quality makes their parts a reliable choice for applications where component consistency and long-term availability are important factors. Engineers designing products with multi-year production runs often prefer established manufacturers and standard packages that offer broad second-source availability and stable pricing over extended procurement windows.
