Open Circuit Inductance (OCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, @ +25C 2. Full Load Inductance (FLL) Test Parameters: 100kHz, 1.0Vrms, @ Isat, @ +25C 3. Irms: DC current for an approximate temperature rise of 40C without core loss. Derating is necessary for AC currents. PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 125C under worst case operating conditions verified in the end application. 4. Isat: Peak current for approximately 30% rolloff @ +25C 5. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * I. Bp-p: (Gauss), K: (K-factor from table), L: (Inductance in H), I (Peak to peak ripple current in Amps). 6.
