Maximum RMS current (sinewave) as a function of frequency
U
AC
is the maximum AC voltage depending on the ambient temperature in the curves “Max. RMS voltage and AC current as a
function of frequency”.
373 - Max. AC voltage as a function of frequency 373 - Max. AC voltage as a function of frequency
371, 372, 373 - Tangent of loss angle as a function of frequency
371, 372, 373 - Insulation resistance as a function of the ambient
temperature (typical curve)
371, 372, 373 - Maximum allowed component temperature rise (ΔT)
as a funtion of the ambient temperature T
