1812SC182KAT1A

The 1812SC182KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive components for industrial and commercial electronics. This part belongs to the 1812 package family, which refers to the physical dimensions of the component—a surface-mount format measuring 1812 in imperial notation (approximately 4.6mm × 3.2mm). This moderate-sized package offers a practical balance between capacitance density and ease of handling in automated assembly environments. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics, serving critical roles in filtering, bypassing, coupling, and decoupling applications across countless circuit designs. The 1812 package is particularly common in industrial control systems, telecommunications equipment, power supply circuits, automotive electronics, and general-purpose consumer and industrial devices where space constraints are less severe than in mobile or portable applications. The "SC" designation in AVX's naming convention typically indicates a standard general-purpose ceramic capacitor with specific electrical characteristics optimized for broad industrial use. These capacitors are designed to provide stable performance across the operating temperature range required by most industrial applications. The ceramic dielectric material used in MLCCs offers good volumetric efficiency, allowing designers to achieve substantial capacitance values in a compact footprint, which is one reason the 1812 package remains popular despite the industry's ongoing push toward smaller packages. Engineers and circuit designers select the 1812SC182KAT1A when they need a capacitor that combines proven reliability, established supply chain availability, and a package size that works well with standard PCB manufacturing and assembly processes. The 1812 format is well-established across the industry, meaning design tools, assembly equipment, and supplier networks are mature and widely accessible. This reduces design risk and procurement complexity compared to more specialized or cutting-edge package options. AVX's manufacturing standards ensure consistent quality and performance, making this part suitable for applications where reliability is important. The ceramic construction provides good frequency response characteristics, making MLCCs effective across a wide spectrum of applications from DC blocking to high-frequency filtering. This capacitor would typically be found in power distribution networks, signal conditioning circuits, timing circuits, and general filtering applications throughout industrial control boards, measurement instruments, and embedded systems where the 1812 package size and ceramic technology represent an appropriate engineering choice for the application requirements.
