Precautions regarding miniaturization
Miniaturization tends to cause a significant increase in the rate of change of the DC bias characteristic.
The DC bias characteristic is a phenomenon in which the static capacitance changes (decreases) from the "nominal value" when a DC voltage is applied to a ceramic capacitor with a high dielectric constant.
The rate of change in the static capacitance when a DC voltage is applied to our "JMK105BJ105KP (1005 (0402)) size" and "JMK063ABJ105KP (0603 (0201) size)" products is indicated below. When a DC voltage of 3V is applied to a ceramic capacitor with a high dielectric constant at a rated voltage of 6.3V and a static capacitance of 1uF, there is a difference in the rate of change of roughly 50% with the 1005 (0402) size and over 60% with the 0603 (0201) size.
