1808SC102KA11A

The 1808SC102KA11A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for general-purpose filtering, decoupling, and signal coupling applications across a broad range of industrial and commercial electronics. This component belongs to AVX's established line of surface-mount ceramic capacitors and uses the standard 1808 package format, which measures approximately 4.5mm by 2.0mm, making it suitable for compact circuit board layouts while remaining large enough for reliable soldering and handling in manufacturing environments. Multilayer ceramic capacitors like this model are foundational components in modern electronics, appearing in power supply circuits, signal conditioning networks, and high-frequency filtering stages. The 1808 footprint represents a mid-range package size—larger than miniature 0402 or 0603 capacitors but smaller than bulkier 1812 or 1825 packages. This positioning makes it ideal for designs where space efficiency matters but component robustness and ease of assembly are also important considerations. The "SC" designation in AVX's naming convention typically indicates a standard commercial-grade capacitor intended for mainstream industrial applications rather than specialized military or automotive qualification levels. These capacitors are widely used in consumer electronics, industrial control systems, telecommunications equipment, and general-purpose embedded systems where cost-effectiveness and reliable performance at nominal operating conditions are priorities. Engineers select the 1808SC102KA11A over alternatives for several practical reasons. The 1808 package offers a good balance between real estate savings and manufacturing compatibility—it is large enough to avoid the handling challenges associated with tiny 0402 parts, yet compact enough for dense PCB designs. AVX's MLCC products are known for consistent quality and widespread availability through distribution channels, reducing supply chain risk for production runs. The specific part number identifies a particular capacitance value and voltage rating within the 1808SC series. When specifying this exact component, an engineer would typically have already determined the required capacitance and voltage from circuit analysis, and would be selecting AVX's offering based on factors such as established supplier relationships, proven performance history in similar designs, package standardization across product lines, or specific environmental and reliability requirements suited to the application. For applications requiring detailed performance data—such as exact capacitance tolerance, temperature coefficient, equivalent series resistance, or frequency response—consulting the relevant technical documentation from AVX is recommended to ensure the component meets your specific circuit requirements.
