12061C683KAT4A

The 12061C683KAT4A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a leading producer of passive electronic components. This part belongs to the 1206 package family, one of the most widely used surface-mount capacitor sizes in modern electronics manufacturing. The 1206 designation refers to the component's compact rectangular footprint measuring approximately 3.2mm by 1.6mm, making it suitable for space-constrained applications while remaining accessible for standard assembly processes. Multilayer ceramic capacitors like this unit are fundamental passive components used across virtually all electronic industries. They function to store and release electrical energy, filter high-frequency noise, couple or decouple signals, and stabilize power distribution within circuits. The ceramic dielectric material used in these capacitors provides good electrical performance in a small physical volume, which is why they dominate modern board designs compared to older electrolytic or film-based alternatives. The "683" designation in the part number indicates the capacitance value, following standard electronic color code and labeling conventions common to the industry. AVX's product lines, including this component, are engineered to meet stringent reliability standards required in demanding applications. The "KAT4A" suffix provides additional information about the specific variant, including voltage rating, tolerance class, and temperature coefficient characteristics specific to AVX's manufacturing specifications. Industries commonly specifying 1206 MLCCs include consumer electronics, telecommunications, automotive electronics, industrial control systems, and medical device manufacturing. These capacitors appear in power supply circuits, RF filtering stages, decoupling networks on logic boards, and signal conditioning circuits. Engineers select components from this family when they need reliable, cost-effective capacitance in high-volume production scenarios where the 1206 size fits thermal and space requirements. The choice of AVX as a manufacturer is significant for procurement purposes. AVX maintains established quality certifications and supply chain visibility that appeal to engineers working on military, aerospace, or automotive programs with traceability requirements. Designers might specify this exact part number rather than alternatives from other manufacturers when they have validated AVX components in their designs, when specific thermal or electrical performance characteristics are critical, or when supply chain continuity and long-term availability are priorities. This component represents a standard solution for general-purpose energy storage and filtering applications where mid-range voltage ratings and established manufacturing processes provide optimal price-to-performance value for high-volume electronic assembly operations.
