12101A221JAT2A

The 12101A221JAT2A is a multilayer ceramic capacitor manufactured by AVX, a globally recognized producer of passive electronic components. This part belongs to the broad family of MLCC (multilayer ceramic capacitor) components, which are fundamental building blocks in modern electronics across virtually every industry vertical. Multilayer ceramic capacitors function as energy storage and filtering elements in electrical circuits. They are constructed from alternating layers of ceramic dielectric material and metal electrodes, compressed into a compact form. The 12101A designation indicates this is a surface-mount device in a standard package size, making it suitable for automated assembly on printed circuit boards. The specific construction and materials used in AVX's formulations are engineered to provide stable performance across a range of operating conditions commonly encountered in industrial equipment. These capacitors are used extensively in power supply circuits, signal filtering, decoupling applications, and frequency compensation networks. Engineers integrate them into consumer electronics, telecommunications infrastructure, industrial control systems, automotive electronics, and medical devices. The multilayer construction allows manufacturers to achieve high capacitance values in physically small packages, which is critical for modern PCB designs where space constraints are significant. The part number itself encodes information about the capacitor's electrical characteristics. The "221" portion of the designation typically relates to the capacitance value, while other segments specify voltage rating, tolerance class, and temperature coefficient performance. AVX's production standards ensure consistent performance across batches, which is important for applications requiring reliable operation over extended periods. When selecting between capacitor alternatives, engineers must consider several factors: required capacitance value, voltage rating, physical package dimensions, temperature stability requirements, and cost. The 12101A221JAT2A from AVX may be specified when its particular combination of these characteristics matches application requirements better than competing options. AVX's reputation for quality and reliability in the passive components market makes their parts a common choice for engineers designing systems where component failure could compromise performance or safety. For designers working on new equipment or replacement designs, this part represents a proven solution from an established manufacturer. Its use in legacy systems also makes it relevant for maintenance, repair, and overhaul applications where component replacement is necessary to restore equipment to operational status. Stocking and specifying well-known manufacturer components like this AVX capacitor reduces design risk and simplifies supply chain management for production environments.
