The recommended land pattern for the 31GF6-E3/73 can be found in the Vishay Intertechnologies' application note AN483, which provides guidelines for surface mount assembly of chip resistors.
The 31GF6-E3/73 is a general-purpose resistor, and its high-frequency performance is not explicitly stated in the datasheet. However, Vishay Intertechnologies recommends using their high-frequency resistors, such as the FHM series, for applications above 100 MHz.
The 31GF6-E3/73 is not AEC-Q200 qualified, which is a standard for automotive-grade components. For automotive applications, Vishay Intertechnologies recommends using their AEC-Q200 qualified resistors, such as the AQMG series.
The MSL of the 31GF6-E3/73 is MSL 1, which means it can withstand a maximum of 30°C/60% RH for 168 hours without being exposed to moisture-related defects.
The 31GF6-E3/73 has a maximum operating temperature of 150°C. While it can be used in high-temperature applications, it's essential to consider the derating curve and ensure the resistor's power rating is not exceeded.
