0805YC471KAT2A

The AVX 0805YC471KAT2A is a ceramic multilayer chip capacitor in the 0805 surface-mount package, a standard size widely adopted across consumer electronics, industrial equipment, and telecommunications applications. This component is part of AVX's established Y5V dielectric series, which is engineered to deliver high capacitance values in compact form factors, making it particularly valuable in space-constrained designs where volumetric efficiency matters. Ceramic chip capacitors like this are fundamental passive components used for energy storage, signal filtering, noise suppression, and power distribution in electronic circuits. The 0805 package dimensions—measuring 2.0 by 1.25 millimeters—represent a common middle ground in modern surface-mount technology, offering a practical balance between handling ease during assembly and board real estate savings compared to larger packages like 1206. The Y5V dielectric classification indicates this capacitor is optimized for applications where capacitance value stability across a moderate temperature range is acceptable in exchange for higher volumetric capacitance density. This makes Y5V capacitors particularly suitable for decoupling, bypass filtering, and energy storage in power supplies, amplifiers, and mixed-signal circuits where precise capacitance tolerances are less critical than in precision timing or filtering applications. Engineers typically specify Y5V ceramics in non-critical coupling and filtering roles where cost-effectiveness and compact board integration take precedence. Compared to X7R or C0G dielectric alternatives, which offer superior temperature and voltage stability, Y5V capacitors provide significantly higher capacitance per unit volume. This characteristic makes them the preferred choice when designers need substantial capacitance within minimal space and can tolerate some performance variation across operating conditions. The tradeoff is well understood in the engineering community and is frequently leveraged in power management circuits, RF applications, and general-purpose filtering throughout industrial and consumer equipment. The 0805 format also presents advantages for manufacturing and rework. The component size is large enough for reliable hand soldering if prototype modifications are necessary, yet small enough for automated pick-and-place assembly at production volumes. This accessibility has made 0805 ceramics a standard specification across countless applications, from automotive electronics to industrial control systems to communications infrastructure. Engineers and procurement specialists specify this exact part when designs call for a proven, readily available capacitor in a compact package with the cost and performance characteristics of the Y5V series. The combination of AVX's established reliability reputation, the standardized 0805 package geometry, and the well-understood performance envelope of Y5V dielectrics makes this component a dependable choice for applications spanning decades of installed equipment.
