negative with temperature changes. The Z5U probably
has the greatest change and will only be found in non-
critical applications such as B+ power
decoupling. These types of capacitors should not be used
in critical applications such as oscillator and timing
circuits.
A ceramic capacitor marked GMV means that the value
marked on the capacitor is the Guaranteed Minimum
Value of capacity at room temperature. The actual value

capacitor is used in bypass applications where the actual
supply value of capacity is not critical.
Ceramic capacitors have been the most popular
capacitors in electronics because of the versatility of the
different temperature coefficients and the cost. When
replacing a ceramic disc capacitor, be sure to replace the
defective capacitor
