Thanks, the tan delta is given on page 19 of the datasheet. This is used to calculate ESR = (tan d) x XcI don't understand the question, the ESR isn't specified in the datasheet. It can be measured with a LCR meter. According to |Z| curve minimum, I would expect an ESR value of 5 to 10 mohm.
Thanks..there goes £180...No, that's not possible. Simply too inaccurate. ESR at different frequencies can be well determined with a LCR meter which does a vectorial measurement.
No, it's because the simple model of losses in the capacitor doesn't hold over a wide range of capacitances and frequencies. They're only providing dissipation factors for conditions where it will yield accurate results. The impedance plots offer a better idea of ESR vs frequencies for specific parts.Yes i see your point, i suppose they dont give tan_d for higher than 1khz for >1uF because the Lseries makes it impossible to measure accurately.
I think this prooves that a frequency analyser is needed. Would you agree?
Of course lead inductance will have an influence on a measurement. The lead inductance is part of the device under test, and the analyzer measures whatever impedance is presented to its measurement terminals.lead and connection inductance and it's resistance with higher freq's can influence an impedance measurement sweep above 1MHz for even the best impedance analysers ....
Do you have a recommendation for a high performance LCR meter?The increasing ESR below 100 kHz shown in the plot isn't necessarily real. We usually see further decrease with high performance LCR meter. I admit that it's not simple to measure R/X < 0.001.

MKP tan d is said to converge against about 10e-4 in Epcos/TDK general information. MKT plot is more realistic.
