How to Choose SMD Resistors (Tolerance, Package & TCR)
A BOM line saying "10kΩ, 0603, 1%" hides dozens of variants across manufacturers, with TCR figures from ±25 to ±200 ppm/°C and 10× price spreads. This guide covers the three parameters that determine which SMD chip resistor belongs on your board, and which belongs in the cost-optimization bin.
