The temperature coefficient shows the
fraction by which the capacitance, measured at +20°C,
changes when the surrounding temperature rises by 1
degree C.
C20 = capacitance at +20°C
CT = capacitance at
T°C
can be
positive or negative. In the case of good capacitors the
TKc is in the region of just a few 10-5/°C.
