Item
• Matching of CERAFILrSFPCA series with IFT is decided by the Qu of IFT
S(3)

and IFT secondary side impedance, |Z2|. Set the Qu at about 40 because
a Qu value which is too high (e.g.,90) may produce ripple in the waveform.
It is recommended to match the impedance of |Z2| with that of the
CERAFILr.
