1812GA221KAT1A

The 1812GA221KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX in the popular 1812 surface-mount package format. This component belongs to the General Application (GA) series, which is designed for standard industrial and commercial electronics applications where reliability and consistent performance are required across a wide operating range. Multilayer ceramic capacitors like this are among the most widely used passive components in modern electronics. They function by storing electrical charge and are essential for filtering, decoupling, timing, and signal coupling applications across virtually every type of circuit board. The 1812 package size—measuring approximately 4.5mm by 3.2mm—offers a practical balance between compact footprint and adequate capacitance and voltage handling capability, making it suitable for space-constrained designs that still demand reasonable electrical performance. The GA series is engineered for general-purpose use in consumer, industrial, and light commercial equipment. These capacitors are particularly valued in power supply circuits, where they help stabilize voltage and suppress noise. They are also commonly found in audio circuits, timing applications, and as bulk capacitors in digital systems. Engineers frequently specify this series for applications where the operating environment is controlled and moderate temperature variations are expected. The 1812 package format offers several practical advantages. Its larger size compared to smaller packages like 0603 or 0805 provides better mechanical durability and ease of handling in manufacturing environments. For engineers designing products that will undergo automated assembly, the 1812 form factor presents fewer placement challenges than ultra-small components. Additionally, the larger case geometry generally accommodates higher voltage ratings and greater capacitance values than smaller packages, which can reduce the overall component count required on a board. AVX's General Application series represents a cost-effective choice for engineers who need dependable ceramic capacitor performance without requiring specialized characteristics. These capacitors work reliably across standard industrial temperature ranges and are produced to consistent quality standards. They are non-polarized, allowing flexibility in circuit design orientation, and feature solderable terminations suitable for standard reflow soldering processes. This part is commonly selected for redesigns or production updates when designers are replacing older through-hole components or when standardizing on surface-mount technology. It is also frequently chosen as a standard catalog item by manufacturers looking to maintain a consistent, manageable bill of materials across multiple product lines.
