This article investigates the impedance of the three standard passive circuit components (R, L, and C) as well as the frequency response of a PCB trace. It is shown that a PCB trace can be modeled as a resonant RLC network just like the standard components and effectively constitutes the fourth circuit component whose frequency behavior directly affects the impedance of the resistors, inductors, and capacitors on a PCB.

Resistivity, Rth and TCR of Resistors

Depending on what units we express l and A in we get different units of r. A common way is by expressing l in m(eter) and A in mm2 r then gets the unit W´mm2/m. If we instead choose l in m and A in m2, the unit for r will be W´mm2/m, which usually is transformed to Wm. That unit often is used for non-metallic materials. If we know the value of r expressed in W´mm2/m, that value has to be multiplied by the factor 10-6 to give the value in Wm. Thus, 10-6 x W×mm2/m = 1 Wm.

Capacitors are used in both analog and digital circuits to remove unwanted signals. The filtering performance of a capacitor or filtering circuit is commonly described in terms of insertion loss. Some of the factors that significantly affect the insertion loss performance of a filtering circuit include configuration of the filtering elements, impedance, and load current.
