12063A221FAT2A

The AVX 12063A221FAT2A is a multilayer ceramic chip capacitor (MLCC) from AVX's established component family. This surface-mount device is designed for general-purpose energy storage, filtering, and signal coupling applications across a broad range of industrial and commercial electronic equipment. MLCCs are among the most widely used passive components in modern electronics. The 12063A221FAT2A utilizes a 1206 case size (imperial designation, approximately 3.2mm × 1.6mm), making it suitable for space-constrained designs while remaining large enough for reliable hand assembly and rework. The "A" designation in the part number indicates this capacitor belongs to a general-purpose series optimized for cost-effective production while maintaining consistent electrical performance across standard industrial temperature ranges. This capacitor type finds application in numerous sectors including consumer electronics, telecommunications equipment, automotive control modules, industrial machinery, and data center infrastructure. Engineers typically specify ceramic chip capacitors for decoupling and bypass applications near integrated circuits, where they suppress voltage transients and high-frequency noise. They are also commonly used in timing circuits, filtering stages of power supplies, and as coupling elements in signal paths where DC blocking is needed. The 12063 form factor represents a popular mid-range size in the MLCC landscape. Compared to smaller 0603 or 0805 packages, the 1206 offers increased capacitance density and often better high-frequency performance due to lower parasitic inductance per unit of capacitance. Conversely, it occupies more board space than miniature packages, making it the practical choice when component density must balance with performance and manufacturing considerations. AVX ceramic capacitors in this family are known for stable performance across temperature and voltage ranges typical of industrial environments. The construction method and material composition of the "A" series provide reliable operation in applications where repeated thermal cycling and mechanical vibration are expected. When selecting a specific MLCC part number, engineers must match the case size, capacitance value, voltage rating, temperature coefficient, and packaging format to their circuit requirements. The 12063A221FAT2A designation encodes these specifications, and specifying this exact part number ensures consistency in procurement and predictable circuit performance. This becomes especially important in production environments where design validation and qualification have been completed against this specific part number, and supply chain standardization reduces technical risk.
