08055A821JAQ2A

The AVX 08055A821JAQ2A is a multilayer ceramic capacitor (MLCC) designed for applications requiring reliable energy storage and filtering in compact form factors. This component belongs to AVX's extensive family of surface-mount capacitors, which are foundational building blocks in modern electronic equipment across industrial, telecommunications, automotive, and consumer applications. Multilayer ceramic capacitors like this part are used primarily for decoupling, bypassing, and filtering functions in circuit boards. They help stabilize power supply voltages, suppress high-frequency noise, and protect sensitive semiconductor devices from voltage transients. Engineers typically place multiple capacitors of varying values across power and ground planes to address different frequency ranges and ensure clean power delivery to integrated circuits. The 08055 designation indicates this is a 0805-sized component in the imperial measurement system (roughly 2.0 mm × 1.25 mm), making it one of the most widely used surface-mount capacitor packages in the industry. This compact size allows for high-density PCB layouts while remaining large enough for reliable automated assembly and field repair when necessary. The 0805 package strikes a practical balance between miniaturization and ease of handling. The "A821J" portion of the part number encodes important electrical characteristics. Capacitors are typically specified by their capacitance value, voltage rating, tolerance class, and temperature coefficient. The "J" suffix commonly indicates a capacitance tolerance specification, while the "A" prefix may denote the voltage rating class. AVX designs these capacitors to meet industry standards and specifications suitable for general-purpose industrial and commercial electronics. Engineers specify AVX MLCCs for their consistent performance, proven reliability in high-volume production environments, and availability through established distribution channels. AVX's manufacturing processes ensure tight tolerances and predictable behavior across temperature ranges commonly encountered in industrial settings. These capacitors are suitable for both consumer-grade and more demanding industrial applications where component reliability directly impacts system uptime. The choice of a specific MLCC often depends on the circuit's operating voltage, required capacitance value, frequency response needs, and environmental conditions. Designers may select the 08055A821JAQ2A when its particular performance envelope—combining the 0805 form factor with AVX's capacitive and voltage specifications—matches their circuit requirements better than alternative packages or manufacturers. For applications ranging from power management circuits to signal conditioning networks, this component represents a standard solution that has proven effective across numerous electronics platforms and manufacturing environments.
