| Category | Typical Validation | |----------|--------------------| | | Check that the tolerance meets the design margin (e.g., 10 kΩ 1 % for precision bias networks). | | Temperature Coefficients | For reference resistors or capacitors in analog sections, confirm that the TC matches the required drift (e.g., C0G/NP0 for filter caps). | | ESD/ESR | Verify that electrolytic caps have ESR suitable for the regulator’s stability loop. | | Power Rating | Ensure resistor wattage > 2× expected dissipation (e.g., 100 Ω 0.5 W for a 0.2 W drop). | | Footprint‑Specific Values | Verify that the physical size can accommodate the value (e.g., 10 µF 6.3 V in a 0805 may be too small). |
