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.

New Surface Mount Resistors Leverage Metal Foil on Ceramic Technology for Enhanced Reliability

The MFC series uses metal foil on ceramic technology, which combines the heat spreading properties of a ceramic substrate with the surge tolerance of a bulk metal alloy resistance element. This, in turn, offers better surge tolerance than thick-film options and lower self-heating levels than thick-film or metal strip resistors, well-suited for automotive, industrial, and medical applications.
