Component Tolerances and Stability The precision of the resistor and capacitor values affects the final impedance calculation. As the frequency approaches zero, the reactance becomes very large, causing the magnitude to approach infinity, effectively blocking DC.

Low frequency regime: High reactance, current is limited. This constant, calculated as the product of resistance and capacitance, dictates how quickly the capacitor charges or discharges.
Carbon film resistors and ceramic capacitors often exhibit higher tolerances compared to metal film or polypropylene components. These real-world factors can significantly alter the theoretical values, especially in high-frequency applications.

Conversely, at very high frequencies, the reactance approaches zero, reducing the total impedance to the value of the resistor alone. Time Domain Considerations While impedance is a phasor concept used in the frequency domain, it is directly linked to the time constant of the circuit, represented by the Greek letter tau.
