1206YD225MAT4A

The 1206YD225MAT4A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components. This part belongs to the 1206 package family, which refers to its surface-mount form factor measuring 3.2mm × 1.6mm. MLCCs like this one are among the most widely used capacitors in modern electronics due to their small size, reliability, and cost-effectiveness. Multilayer ceramic capacitors function as energy storage and filtering devices in electronic circuits. They are essential for decoupling, bypassing, filtering, and coupling applications across virtually every type of electronic equipment. The 1206 package size represents a popular midrange option that balances capacitance value against physical footprint, making it suitable for space-constrained applications while remaining easy to handle and assemble using standard manufacturing equipment. The "YD" designation in this part number indicates this capacitor is part of AVX's Y5V or similar dielectric material class, which is commonly specified for general-purpose applications where moderate capacitance stability across temperature ranges is acceptable. Capacitors in this family typically offer high capacitance density, making them valuable when designers need substantial capacitive performance in a compact footprint. The "225" portion of the part number traditionally indicates the capacitance value using a three-digit code common in the electronics industry. Engineers specify this exact part number when their circuit design requires the specific combination of package size, capacitance value, voltage rating, and dielectric characteristics that the 1206YD225MAT4A provides. The AVX brand carries particular weight in industrial and mission-critical applications where component reliability and consistent quality from a recognized manufacturer are paramount. AVX capacitors are widely qualified and used in automotive, telecommunications, industrial control, medical devices, and consumer electronics. The surface-mount 1206 package is compatible with automated assembly processes including pick-and-place equipment and reflow soldering, making this component economical for both prototype development and high-volume production runs. Its standardized dimensions and footprint make it a drop-in replacement option when redesigning or updating existing products. When selecting this component, engineers should verify that the capacitance value, voltage rating, and temperature stability characteristics match their specific circuit requirements. The 1206 package also offers excellent thermal characteristics during manufacturing and operation, which contributes to the overall reliability and longevity of the finished assembly. For applications requiring high-volume supply and design consistency, AVX's broad production capacity makes this part a practical choice.
