Clearance Holes for Metric Fasteners

When designing a PCB board, it is important to determine the necessary clearance for screw holes. The table below shows the general screw sizes and the corresponding hole clearances.


Hot-Swap Circuits with Inrush Current Limiter

  To provide continuous current sensing and limiting, this hot-swap circuit uses a PNP transistor and a current sense resistor of 0.333R. Wh...
