5.1 R1_n, R2_n, R3_n, C2_n, C5_n

R1_n, R2_n, and R3_n are factory-installed 0-Ω 0603 resistors.

C2_n and C5_n, are not populated.

Collectively, these pads allow user-defined filters for the input pins (IN+ and IN–) and the output pin (OUT) of the INA241x. If a filter is desired, remove these resistors and replace them with > 0-Ω SMT resistors and populate the capacitor pads with capacitors. Consider the input bias current of the device when using input filtering.
