Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.10Vrms, 0.0Adc 2. Irms: DC current for an approximate temperature rise of 40C without core loss. De-rating is necessary for AC currents. Temperature rise is dependent upon several factors, including the PCB pad layout, trace thickness and width, air-flow and proximity to other heat generating components. It is recommended the part temperature not exceed 125C under worst case operating conditions and therefore, the temperature rise should be verified in the end use application. Irms testing was performed on a 19.05mm long x 6.35mm wide x 0.070mm thick copper trace in still air. 3. Isat: Peak current for approximately 30% rolloff at +25C. 2 www.eaton.com/elx 4. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * DI.Bp-p : (Gauss), K: (K-factor from table), L: (inductance in H), DI =(peak-to-peak ripple current in amps). 5.
