PHYSICAL PROPERTIES
The properties of MLC’s are decided by their chemical
composition and physical makeup. As manufacturers use
slightly different compositions and designs this means that
all MLC’s do not have identical properties. Most systems
are, however, based on doped barium titanate raw materi-
als and basically similar designs. There will be minor differ-
ences in value for some of the physical constants quoted
but these should not prove significant for practical purposes.
Temperature
Coefficient of expansion (CTE)
This varies according to which axis of the chip is being
measured.
Across terminations (L)
Across chip (W)
Electrode (Pd/Ag)
It should be remembered that in attempting to match circuit
board material with MLC’s that the dynamic system should
be considered (power on temperature rise) not the static
system (uniform temperature rise).
