1206YC105KAT4A

The 1206YC105KAT4A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established producers of passive electronic components. This part belongs to the 1206 package family, a widely adopted surface-mount capacitor size that measures approximately 3.2mm by 1.6mm, making it suitable for space-constrained circuit board layouts while remaining easy to handle and solder using standard manufacturing equipment. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics, serving critical roles in power supply filtering, signal coupling and decoupling, noise suppression, and timing circuits across countless applications. The 1206 package strikes an effective balance between component density and thermal performance, allowing designers to achieve reasonable capacitance values without requiring excessive board real estate. The "YC" designation in AVX's product line typically indicates a general-purpose, commercial-grade ceramic capacitor intended for standard industrial and consumer applications. These capacitors feature a ceramic dielectric material sandwiched between multiple metal layers, which allows manufacturers to achieve relatively high capacitance in small packages. The construction method makes MLCCs reliable for repetitive thermal cycling and mechanically robust under normal handling and assembly processes. Engineers frequently specify capacitors in the 1206 package when designing power delivery networks, analog signal conditioning circuits, and digital logic boards. The compact footprint makes 1206 MLCCs particularly valuable in portable equipment, telecommunications hardware, automotive electronics, and industrial control systems where board space is at a premium. Additionally, the standardized package size ensures broad availability across multiple manufacturers and suppliers, reducing supply chain risk for production environments. When choosing between capacitor alternatives, engineers typically consider several factors including package size, required capacitance value, voltage rating, temperature stability characteristics, and cost. The 1206 package offers a practical middle ground for many applications—larger than smaller packages like 0603 or 0402, yet smaller than 1210 or 1812 packages. This makes the 1206 an industry standard choice that balances performance requirements against practical manufacturing constraints. AVX's reputation for manufacturing consistency and reliability makes this part a dependable choice for applications where component quality directly impacts system performance. The 1206 MLCC format has proven itself across decades of electronic design, making it a proven solution for engineers developing both prototype and production-volume designs requiring stable, compact capacitive filtering and energy storage.
