impedance forms a 40Hz low-pass filter. Since the thermal time constant of the LM50-Q1 is much slower than

the 25ms time constant formed by the RC, the overall response time of the device is not significantly affected.

For much larger capacitors this additional time lag increases the overall response time of the LM50-Q1 .
