Q&A derating MLCC ripple current for transient current spikes

Remember that RMS measurements assume at least 1 cycle or in your case 100 ms or 10 Hz.  So the Ripple Current/rms vs Temp rise is always valid for any duty cycle.  This means in theory you can raise the current significantly since the spike is a very low duty cycle. In practice, the device will have some nonlinear fuse limit.
