0805YC103J4T2A

# Product Description: 0805YC103J4T2A The 0805YC103J4T2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for general-purpose applications across industrial, consumer, and telecommunications electronics. This component belongs to the 0805 package family, one of the most widely used standard surface-mount capacitor formats in modern PCB design. Multilayer ceramic capacitors like this part function as energy storage and filtering elements in electronic circuits. They are essential for decoupling power supplies, blocking DC signals while passing AC, filtering high-frequency noise, and timing circuit applications. The 0805 package format—measuring approximately 2.0mm by 1.25mm—offers a practical balance between component density and ease of manufacturing, making it suitable for both hand assembly and high-volume automated production environments. The "YC" designation within AVX's product nomenclature indicates this capacitor is part of their standard commercial-grade ceramic capacitor series. These components typically feature X7R or similar dielectric materials, which provide relatively stable capacitance across a moderate temperature range and voltage operating window. This makes them well-suited for applications where performance consistency is important but extreme environmental conditions are not expected. Engineers commonly specify ceramic capacitors in this package size for power supply bypassing near integrated circuits, where they suppress voltage transients and supply noise. They are equally common in analog signal conditioning circuits, RF applications requiring impedance matching networks, and general noise filtering throughout consumer electronics, industrial control boards, and embedded systems. The compact 0805 size allows designers to place multiple capacitors close to their load points without consuming excessive PCB real estate. The choice of this specific part number over alternatives typically depends on matching the capacitance value, voltage rating, and tolerance requirements of the circuit design. AVX components are recognized for consistent manufacturing quality and reliable performance in production environments. Engineers working with established component supply chains often prefer branded MLCCs from recognized manufacturers to ensure long-term availability and consistent electrical characteristics across production batches. This capacitor would typically be paired with other passive and active components as part of a larger circuit board assembly. Its ceramic construction makes it durable and resistant to mechanical stress, while the surface-mount termination enables efficient automated placement during manufacturing. Whether used in new product development or as a replacement component in mature designs, the 0805 format remains a standard specification across the electronics industry.
