2-1. Temperature Characteristic
Temperature characteristics of MLCC capacitors are shown in Fig.1 below:
At the measurement conditions of 1kHz, 1Vrms, whereas capacitance change ratio of the
X7R-characteristic is within ± 15% at maximum, The Y5V-characteristic capacitor is allowed to
over a wider range of
+22% /-82%. Dissipation factor also changes according to measurement
temperature, which tends to go up in lower temperatures for both X7R- and Y5V- characteristic
capacitors.
