1206YC225K4T2A

The 1206YC225K4T2A is a multilayer ceramic chip capacitor (MLCC) manufactured by AVX, one of the established producers of passive electronic components. This part is packaged in the standard 1206 form factor, a surface-mount package measuring approximately 0.12 by 0.06 inches, making it suitable for modern PCB assembly processes and high-density circuit layouts. Multilayer ceramic capacitors are fundamental passive components found in virtually every contemporary electronic device. They store and discharge electrical charge, filter noise from power supplies, couple and decouple AC signals, and stabilize voltage rails in digital and analog circuits. The 1206 package size represents a common middle ground in the capacitor size spectrum, offering adequate capacitance values while remaining practical for standard manufacturing equipment and hand repair scenarios. The "YC" designation in AVX's naming convention typically indicates a ceramic dielectric composition selected for specific performance characteristics, often relating to temperature stability and voltage rating. The "225K" portion of the part number indicates a nominal capacitance value in the low microfar range, with the "K" representing the tolerance class. Capacitors of this value and package size are widely used in consumer electronics, telecommunications equipment, industrial control systems, and automotive applications where moderate capacitance and compact size are required. Engineers typically specify AVX MLCCs for reliability and consistency. AVX maintains strict quality standards and provides extensive documentation supporting their components across various temperature and voltage operating conditions. The 1206 package itself offers practical advantages: it's large enough to provide adequate capacitance for many filtering and coupling applications, yet small enough to enable space-efficient designs. It's compatible with both automated and manual assembly workflows, reducing manufacturing complexity. The choice of a specific MLCC often depends on the required voltage rating, temperature stability class, and dissipation factor at the operating frequency. The 1206 format provides flexibility across these parameters, as manufacturers offer numerous dielectric types and ratings within this footprint. Designers might select this exact part when their design requires a capacitor that balances capacitance value, voltage withstand capability, physical size constraints, and long-term availability from a established supplier. This component would be stocked by electronic distributors serving professional engineers, technicians, and manufacturers who need reliable passive components for prototyping, production, repairs, and field service applications.
