impedance forms a 40Hz low-pass filter. Since the thermal time constant of the LM50 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 .
