Notes to Figure 5 (Page 100)
The PT Toroid Series inductance is specified at AC and DC signal levels which have 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
waveform having less than a 1% ripple content. When considering the AC waveform, both the frequency and voltage level 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 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 voltage/frequency
factor is calculated to be: 1VRMS/25,000Hz = 40 x 10–6. Referring to the graph, a 39% increase in inductance would be expected.
Notes to Figure 6 (Page 100)
Typical saturation effects as a function of DC flowing through the part. Data is representative of a DC waveform with
less than 1% ripple, and an AC waveform 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, waveform distortion, etc.…
Delevan Sales/Engineering staff is available to provide information as needed to fit each application.
