Chip resistors dominate digital boards. Pick case size, tolerance, TCR, and power rating from the datasheet for your ambient temperature.
Parameters
| Parameter | Why it matters |
|---|---|
| Case (0402, 0603, …) | Power and assembly |
| Tolerance (1%, 5%) | Divider accuracy |
| Power | I²R heating at max current |
