5.4.1. Resistors and Capacitors
Choose the smallest footprint available when selecting discrete components such as resistors and capacitors. The small footprint means that the pad on the board can be small and that the parasitic capacitance and inductance will also be small. Intel typically uses 40 mil × 20 mil (0402) package components for high-speed signals.
Inductors typically require bigger footprints because they are often used for power supply filtering and must be bigger to support high currents without saturating.
- DC resistance
- AC impedance
- Current handling capability
