Compared with conventional plastic packages, ceramic small outline packages offer lower thermal expansion mismatch, enhanced hermeticity, and improved resistance to mechanical shock and vibration. Their compact outline and wing-shaped leads make them ideal for high-density PCB assembly while reducing stress on solder joints.
