08055A821J4T2A

The AVX 08055A821J4T2A is a thin-film ceramic chip capacitor designed for demanding industrial and commercial electronics applications. This surface-mount component belongs to AVX's established 0805 package family, which represents a widely standardized form factor measuring approximately 2.0mm by 1.25mm. The compact size makes it well-suited for modern high-density PCB layouts while maintaining accessibility for both automated assembly and rework operations. Ceramic chip capacitors like this model are fundamental building blocks in modern electronics, serving critical roles in filtering, decoupling, coupling, and energy storage circuits. The 08055A821J4T2A specifically falls into the general capacitance range and performance class typical of mid-range ceramic capacitors, making it applicable across numerous industrial control systems, power supply circuits, signal conditioning modules, and telecommunications infrastructure. These components are particularly valued in applications requiring stable performance across moderate temperature ranges and where space constraints demand compact component footprints. The AVX designation in the part number indicates this capacitor benefits from AVX Corporation's long-established manufacturing expertise in ceramic dielectric technology. AVX is recognized within the industry for consistent quality control and reliable performance in both commercial and specialized industrial segments. The specific construction of ceramic chip capacitors from established manufacturers typically emphasizes consistent electrical behavior, low equivalent series resistance, and predictable aging characteristics—factors that engineers depend upon when designing circuits requiring long-term reliability. Engineers typically specify this exact part number when design requirements call for the specific performance characteristics associated with this particular capacitance value and package combination. The 0805 package size represents an optimal balance point in many designs: smaller than 1206 packages for space-constrained applications, yet larger than smaller 0603 or 0402 packages, offering better current-handling capability and thermal performance. This makes the 08055A821J4T2A a practical choice in retrofit scenarios, legacy system repairs, and new designs where moderate component density and serviceability are both important considerations. In industrial automation, medical device electronics, and professional audio equipment, consistency and reliability are paramount. The combination of AVX's manufacturing heritage and the proven 0805 package format makes this capacitor a dependable specification choice for engineers designing systems where component failure rates must remain predictable and where replacement compatibility with future production runs is important.
