1-5. Component dependency factors
The measured impedance value of a component depends on several measurement conditions, such
as frequency, test signal level, and so on. Effects of these component dependency factors are differ-
ent for different types of materials used in the component, and by the manufacturing process used.
The following are typical dependency factors that affect measurement results.
Frequency:
Frequency dependency is common to all real-world components because of the existence of para-
sitics. Not all parasitics affect the measurement, but some prominent parasitics determine the com-
ponent’s frequency characteristics. The prominent parasitics will be different when the impedance
value of the primary element is not the same. Figures 1-7 through 1-9 shows the typical frequency
response for real-world resistors, inductors, and capacitors.
