Figure 1-11. DC bias dependencies of ceramic capacitors and cored-inductors

Temperature:

Most types of components are temperature dependent. The temperature coefficient is an important

specification for resistors, inductors and capacitors. Figure 1-12 shows some typical temperature

dependencies that affect ceramic capacitors with different dielectrics.

Other dependency factors:

Other physical and electrical environments, e.g., humidity, magnetic fields, light, atmosphere, vibra-

tion, and time may change the impedance value. For example, the capacitance of a high-K type

dielectric ceramic capacitors decreases with age as shown in Figure 1-13.
