Resistor Values for PCB Design: Tables and Selection Rules
Resistor values affect current, voltage division, signal stability, heat, tolerance error, and long-term sourcing. A 10kΩ resistor may be a good GPIO pull-up, but the same value can be wrong for a precision ADC divider or a high-speed bus. Good resistor selection is not just a calculation. Before a value reaches the BOM, engineers should […]
