Voltage Coefficient Of Ceramic Capacitors
At 85 c with 0v bias the capacitance decreases by 68 14 from 4 7µf to 1 5µf.
Voltage coefficient of ceramic capacitors. Vcc is a result of the contruction of the mlcc. Test voltages related to iec 60384 8 21 9 22. Voltage coefficient for class ii ceramic capacitors. To test safe construction.

Please note that among ceramic capacitors the capacitance especially of capacitors classified as high dielectric constant b x5r r x7r characteristic may differ from the nominal value when a dc voltage is applied. At 5v the typical capacitance is 92 9 below nominal or 0 33µf. September 29 2015.
Factors that influence vcc. Furthermore in periodic life time tests endurance tests the voltage proof of ceramic capacitors is tested with increased test voltage 120 to 150 of u r to ensure safe construction. Biasing this 6 3v rated capacitor with 5 volts will result in a capacitance that is 14 times smaller than nominal. Vcc or voltage coefficient of capacitance is a decrease in capacitance under applied dc voltages that happens in in classii and class iii mlccs.
