0805YC394JAT2A

The 0805YC394JAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, supplied in the widely-used 0805 surface-mount package. This compact component is designed for general-purpose energy storage, filtering, and signal coupling applications across consumer, industrial, and telecommunications equipment. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics. They function by storing electrical charge across multiple layers of ceramic dielectric material, with metallic electrodes deposited between each layer. The 0805 package format—measuring approximately 2.0mm by 1.25mm—offers an optimal balance between capacitance density and ease of assembly on standard PCB manufacturing equipment. This makes it one of the most prevalent capacitor packages in production today. AVX's 0805 ceramic capacitor series is engineered for reliability in demanding environments. These components excel in bypass and decoupling applications, where they suppress voltage ripple and noise on power distribution networks. They're equally valuable for AC coupling in analog signal paths, timing circuit filtering, and EMI suppression. The compact footprint allows engineers to pack filtering functionality into space-constrained designs without sacrificing performance. The designation "YC" in this part number indicates this capacitor belongs to AVX's Y5V or general industrial-grade dielectric class, which provides stable performance across a broad operating temperature range suitable for most industrial applications. Ceramic capacitors in this family are preferred in cost-sensitive designs where high volumetric efficiency and proven reliability are required. Engineers typically specify 0805 ceramic capacitors when they need a cost-effective, readily available solution with established supply chains and manufacturing compatibility. Unlike electrolytic or film capacitors, multilayer ceramic designs offer superior high-frequency performance, lower ESR (equivalent series resistance), and smaller physical footprints. They withstand automated soldering processes reliably and integrate seamlessly into modern surface-mount assembly workflows. The 0805 format is particularly common in power management circuits, microcontroller reference designs, RF applications, and industrial control systems. Component miniaturization across consumer electronics and IoT devices has made 0805 capacitors ubiquitous, ensuring broad availability and competitive pricing compared to larger packages. For applications requiring specific electrical characteristics—including precise capacitance value, voltage rating, temperature coefficient, or frequency response—consulting the manufacturer's documentation for this part number is recommended. AVX maintains comprehensive technical resources to support design validation and performance verification.
