Open Circuit Inductance (OCL) Test Parameters: 100 kHz (1 MHz for R022), 0.1 Vrms, 0.0 Adc, +25 °C 2. Full Load Inductance (FLL) Test Parameters: 100 kHz (1 MHz for R022), 0.1 Vrms, Isat1, +25 °C 3. Irms: DC current for an approximate temperature rise of 40 °C 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 +125 °C underworst case operating conditions verified in the end application. 4. Isat1 : Peak current for approximately 20% rolloff @ +25 °C 5. Isat2 : Peak current for approximately 20% rolloff @ +100 °C 6. Isat3 : Peak current for approximately 20% rolloff @ +125 °C 7. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ∆I * 10-3. Bp-p:(Gauss), K: (K-factor from table), L: (Inductance in nH), ∆I (Peak to peak ripple current in Amps). 8.
