Understanding the temperature coefficient vs drift of ceramic capacitors
My understanding of the temperature coefficient until now was, that the TCC is a value in ppm/K (or ppm/°C) that stands for the change of the capacitance when changing the temperature. So for example a NP0 would have a TCC of 0±30 ppm/K. Drift: The drift of the capacitor is a value, that determines how much the capacitance changes …
