Datasheet
MAX31865 on Analog.com
This capacitor is for filtering high frequency noise events. Events like overvoltage, undervoltage or enabling VBIAS can produce high frequency noise. This capacitor works with the resistance of the RTD and acts as a low pass filter. The values given in the datasheet are recommendations only and you can change the capacitor value to vary the cutoff frequency of the filter.
