08055A390JAQ2A

# 08055A390JAQ2A - AVX Multilayer Ceramic Capacitor The 08055A390JAQ2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components. This part belongs to the 0805 package family, which represents one of the most widely used surface-mount capacitor formats in modern electronics manufacturing. Multilayer ceramic capacitors are fundamental building blocks in virtually all electronic circuits. They store electrical charge and are used for filtering, coupling, decoupling, and bypassing applications. The 0805 package size—measuring 0.080 inches by 0.050 inches—strikes an effective balance between compact form factor and ease of assembly, making it ideal for densely populated circuit boards while remaining compatible with standard automated pick-and-place equipment. The "390" designation in the part number indicates the capacitance value. AVX's comprehensive MLCC portfolio includes this value across multiple dielectric classes to serve different performance requirements. Engineers select specific dielectric types based on their application's voltage stability needs, temperature characteristics, and frequency response. Some applications prioritize stable capacitance across temperature ranges, while others may accept capacitance variation in exchange for higher volumetric efficiency. The 08055A390JAQ2A finds widespread use across numerous industries. In consumer electronics, these capacitors support power supply circuits, signal conditioning, and noise filtering. Industrial control systems rely on them for reliable operation in demanding environments. Telecommunications and networking equipment incorporate them extensively for signal integrity and power distribution. Medical device manufacturers specify them where miniaturization and reliability are critical. Automotive applications use them in body control modules, infotainment systems, and sensor conditioning circuits. Engineers typically specify this exact part when combining several practical considerations. The 0805 package offers proven manufacturability with high first-pass yield rates. AVX's reputation for quality and consistency appeals to designers working on mission-critical applications where component failure rates directly impact reliability metrics. The part's proven track record in high-volume production runs reduces supply chain risk compared to more exotic alternatives. When evaluating alternatives, engineers must consider that different capacitor families involve tradeoffs. Ceramic capacitors like the 08055A390JAQ2A offer compact size, low cost, and good high-frequency performance but feature voltage-dependent capacitance in some dielectric types. For applications where these characteristics align with design requirements, the 08055A390JAQ2A represents a standard, reliable choice backed by established manufacturing processes and broad industry acceptance.
