Package characteristics
STM32F103xF, STM32F103xG
Using the values obtained in Table 72 T_Jmax is calculated as follows:
– For LQFP100, 46 °C/W
T_Jmax = 115 °C + (46 °C/W × 134 mW) = 115 °C + 6.2 °C = 121.2 °C
This is within the range of the suffix 7 version parts (–40 < T_J < 125 °C).
In this case, parts must be ordered at least with the temperature range suffix 7 (see
Table 73: STM32F103xF and STM32F103xG ordering information scheme).
