KOA Speer Chip Resistor Heat and Temperature Rise
KOA Speer Chip Resistor Heat and Temperature Rise Technical Note explains how applied power and PCB heat dissipation influence temperature rise and long-term stability. The RK73B, SG73P, and WK73R resistors show similar behavior at equal power but need careful thermal management to maintain reliability. These high-rated parts rely on efficient multilayer PCB design to prevent excessive heating.
