1812CC223KAT1A

The 1812CC223KAT1A is a multilayer ceramic chip capacitor manufactured by AVX, one of the established leaders in passive component production. This component belongs to the 1812 package family, which represents a surface-mount form factor measuring 18mm by 12mm with a thickness suited for standard PCB assembly processes. Capacitors in this package size occupy a middle ground between smaller 0805 and 1206 packages and larger form factors, making them popular for applications requiring moderate capacitance values without excessive board space consumption. Multilayer ceramic capacitors (MLCCs) like this part are fundamental building blocks in modern electronics, functioning to store electrical charge, filter noise, couple signals, and stabilize power supplies across numerous circuit topologies. The 1812 package is particularly common in industrial equipment, telecommunications infrastructure, automotive electronics, power conversion circuits, and consumer electronics where space constraints are less severe than in mobile devices but reliability and performance remain critical. AVX's ceramic capacitor lines are recognized in the industry for consistent quality and availability across commercial and industrial temperature ranges. The "CC" designation in this part number indicates it belongs to a ceramic capacitor family, with the specific material composition and electrical characteristics optimized for general-purpose applications. The alphanumeric suffix portion of the designation typically encodes additional information regarding voltage rating, capacitance value, tolerance, and temperature coefficient—characteristics that determine how this capacitor performs across its intended operating environment. Engineers select 1812 ceramic capacitors for several practical reasons. The package size allows for higher capacitance density compared to smaller alternatives while remaining compatible with automated surface-mount assembly equipment standard in modern manufacturing. The inherent reliability of multilayer ceramic technology, combined with AVX's manufacturing standards, makes these parts suitable for applications where component failure could compromise system performance or safety. Additionally, the 1812 package strikes an economic balance—it costs less than much larger packages while offering better performance than aggressively miniaturized alternatives in many circuit designs. This component would typically be encountered in applications requiring filtering, decoupling, or energy storage at moderate voltage and capacitance levels. Its selection depends on specific circuit requirements including the required capacitance value, operating voltage, frequency response characteristics, and temperature stability needed for the application. Engineers designing power management circuits, signal conditioning stages, or electromagnetic compatibility filtering often incorporate multiple 1812 capacitors in parallel or series configurations to achieve desired electrical performance and redundancy.
