# AVX 12102C123JAT2A Product Description The AVX 12102C123JAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and energy storage applications in industrial and commercial electronic equipment. This component belongs to AVX's established MLCC portfolio, which serves as a foundational building block in power distribution, signal conditioning, and noise suppression across countless circuit designs. Multilayer ceramic capacitors like this part are essential in modern electronics because they provide stable capacitance performance across temperature ranges while maintaining compact physical footprints. The 1210 case size—representing 12.7mm by 10.2mm—offers a good balance between capacitance density and ease of integration into standard printed circuit boards. This package format is widely used in industrial control systems, telecommunications infrastructure, automotive electronics, and power supply designs where space is limited but reliable performance is critical. AVX MLCCs are manufactured using proprietary ceramic dielectric formulations that deliver consistent electrical characteristics. Components in this family are typically specified for applications requiring stable capacitance across operating temperature ranges, low equivalent series resistance (ESR), and reliable performance in repeated power cycling scenarios. Engineers often select AVX capacitors when they need predictable long-term behavior in harsh industrial environments or demanding applications with extended service life requirements. The 12102C123JAT2A designation indicates this is a standard commercial-grade MLCC suitable for mainstream industrial applications. Common use cases include input and output filtering on switching power supplies, bypass capacitance on digital logic circuits, voltage regulation circuits, and AC signal coupling applications. In industrial equipment, these capacitors frequently appear in control boards, motor drivers, frequency inverters, and sensor interface circuits where electrical noise must be attenuated or charge storage is required. Engineers specify this particular part number over alternatives when they need proven reliability from an established manufacturer, compatibility with standard assembly processes, and consistent performance documentation across manufacturing batches. AVX's reputation for quality and traceability makes their MLCCs preferred choices in applications requiring compliance documentation, long-term availability, or operation in temperature-extremes or vibration-prone environments. The through-hole or surface-mount configuration of this component—depending on the exact variant in your application—ensures straightforward integration into legacy systems or modern automated assembly lines. For industrial buyers evaluating component selections, the AVX brand provides the combination of proven field performance, technical support, and supply chain consistency that reduces development risk in critical applications.
