Notes to Figure 5 (P age 95) The PT Toroid Series inductance is specified at AC and DC signal le vels which ha ve no significant effect
on the permeability of the powdered iron toroidal core. Superimposed AC and DC voltages will change the permeability and therefore
the inductance, under operating conditions. Typically, DC currents will reduce the inductance, while AC signals will increase the
inductance up to a point, before beginning to decrease. Supporting information is provided, detailing the AC or DC effects upon each
part. Saturation resulting from DC currents is specified with w av eform having less than a 1% ripple content. When considering the AC
waveform, both the frequency and voltage le vel must be taken into account. As an aid in defining what effect the alternating sine wave
signal will have, the voltage/frequency factor curve can be used. To determine what change of inductance can be expected at a given
voltage level and frequency, simply divide the sinusoidal RMS voltage by the frequency. The voltage is in v olts and the frequency is in
hertz. As an e xample , if using part number PT25-680 at a 1VRMS signal level, and a frequency of 25KHz, the v oltage/frequency factor
is calculated to be: 1VRMS/25,000Hz = 40 x 10–6. Referring to the gr aph, a 39% increase in inductance w ould be expected.
Notes to Figure 6 (P age 95) Typical saturation effects as a function of DC flo wing through the part. Data is representative of a DC
waveform with less than 1% ripple, and an AC w av eform less than 10 gauss .
Note This information is intended to be used in assisting the designer in part selection. Each operating application may contain other
variables which must be considered in part selection; such as temperature effects , w av eform distortion, etc.... Delevan Sales/Engin-
eering staff is available to pro vide information as needed to fit each application.
