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 specied 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 dening 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 106. 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 owing 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/Engin eering staff is available to provide information as needed to t each application 270 Quaker Rd., East Aurora NY 14052 Phone 716-652-3600 Fax 716-652-4814 E-mail: apisales delevan com www.delevan.com 9/2021Power Inductors mm Inches mm Inches mm Inches mm Inches mm Inches mm Inches RATED IDC (Amps) DCR MAX.
