With component bodies shrinking to 0201 packages (0.6mm x 0.3mm), manufacturers have abandoned full part numbers for cryptic 2, 3, or 4-character codes. Enter the —a snapshot in time that remains a cornerstone reference for decoding these miniature mysteries. Why the 2021 Edition? While component databases are updated annually, the 2021 databook represents a "sweet spot" in electronics history. It captures the tail end of mature through-hole technology transitions and the peak of miniaturization for IoT and 5G infrastructure components. In the world of modern electronics, Surface Mount
