The voltage limit given in the warning is the peak voltage, so we need to convert it to the corresponding rms voltage. The relationship between peak voltage (Vp) and rms voltage (Vrms) for a sinusoidal signal is Vrms = Vp/sqrt(2). Plugging in the given voltage limit, we get Vrms = 11/sqrt(2) = 7.78 V. Therefore, the highest rms voltage that can be supplied to the component while staying below the voltage limit is 6 V.
