EEVblog #626 – Ceramic Capacitor Voltage DependencyPosted on June 7th, 2014 20 comments
Dave explains, shows, and measures a potentially big trap with using high value ceramic capacitors.
If your 10uF capacitor really 10uF in your circuit?
Those humble X7R caps you think are a “stable” dielectric? think again…
Class II and above ceramic capacitors can vary their capacitance drastically with DC bias voltage level and also the applied AC voltage.
