Derating ceramic capacitors
WebJan 12, 2024 · 3. Capacitance of Class 2 dielectrics (X7R, etc) varies a lot with temperature and electric field, the latter being dependent on voltage across the cap and distance between electrodes. So if you make a filter with a class 2 ceramic cap, its cutoff frequency will move around in a wide range depending on DC bias and temperature.
