Notes to Figure 5 (P age 100) The PT Toroid Series inductance is specified at AC and DC signal le vels which have no significant eff ect
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 A C or DC effects upon each
part. Saturation resulting from DC currents is specified with wav ef orm having less than a 1% ripple content. When considering the AC
wa vef orm, both the frequency and voltage level m ust be tak en into account. As an aid in defining what effect the alternating sine wav e
signal will have, the v oltage/frequency factor curve can be used. To determine what change of inductance can be expected at a given
voltage lev el and frequency, simply divide the sinusoidal RMS voltage by the frequency. The voltage is in volts and the frequency is in
hertz. As an example , if using part number PT25-680 at a 1VRMS signal level, and a frequency of 25KHz, the v oltage/frequency f actor
is calculated to be: 1VRMS/25,000Hz = 40 x 10–6. Referring to the gr aph, a 39% increase in inductance w ould be e xpected.
Notes to Figure 6 (P age 100) Typical saturation eff ects as a function of DC flowing through the part. Data is representative of a DC
wa vef orm with less than 1% ripple, and an A C 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 m ust be considered in part selection; such as temperature effects, waveform distortion, etc.…
Delevan Sales/Engineering staff is av ailable to provide information as needed to fit each application.
