CHV2220N500105KXT Capacitance vs. DC bias voltage

Where can I find datasheet for this device or similar X7R 1kV caps from Cal-chip, that shows a plot for the effective capacitance as a function of DC bias?

Hello,

Thank you for your inquiry.

All of Cal-Chips capacitor documentation is available here

I do not see that they have published the information you are looking for.
