0805YC103MAT2A

The 0805YC103MAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX in the popular 0805 surface-mount package size. This component is designed for general-purpose energy storage, filtering, and decoupling applications across a wide range of electronic equipment and industrial systems. Multilayer ceramic capacitors like this model serve as fundamental building blocks in modern electronics. They are used to smooth voltage supplies, filter high-frequency noise, decouple integrated circuits from power distribution networks, and provide local charge storage near active components. The 0805 package is one of the most widely adopted SMD capacitor sizes in the industry, balancing physical compactness with ease of assembly on automated production equipment. The "YC" designation in the part number indicates this capacitor belongs to AVX's ceramic capacitor family optimized for general electronics applications. Capacitors in this series are typically found in consumer electronics, telecommunications infrastructure, industrial control boards, automotive systems, and medical devices where reliable, cost-effective filtering and decoupling are required. The 0805 form factor measures 2.0 x 1.25 mm, making it suitable for high-density PCB designs while remaining compatible with standard surface-mount assembly processes. This size offers a practical middle ground—smaller than 1206 packages but with better current handling and thermal characteristics than miniature 0603 packages. Engineers typically specify this particular part when designing mixed-signal circuits, power management stages, or sensor interfaces where ceramic capacitors provide adequate performance at competitive cost. The MLCC construction offers stable capacitance across a reasonable temperature range, making it suitable for applications that experience modest thermal variation. AVX's manufacturing quality and consistent availability make this series a reliable choice for volume production runs. One key consideration for engineers is that ceramic capacitors exhibit capacitance variation with applied voltage and temperature, which differs from film or electrolytic alternatives. This characteristic is well-understood and accounted for in most modern circuit designs. The 0805YC103MAT2A would be specified when the designer has confirmed that these normal MLCC properties are acceptable for the intended application. The widespread adoption of 0805 capacitors means strong supply chain consistency, competitive pricing across distributors, and broad familiarity among PCB assembly partners. This part represents a pragmatic choice for mainstream industrial and consumer electronics applications where performance requirements do not demand specialized ceramic formulations or exotic package sizes.
