Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.25 Vrms, 0.0 Adc, @ +25 C 2. Full Load Inductance (FLL) Test Parameters: 100 kHz, 0.25 Vrms, @ Isat, @ +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 under worst case operating conditions verified in the end application. 4. Isat: Peak current for approximately 20% rolloff @ +25 C- HCM1104-R20-R to HCM1104-R90-R 5. Isat: Peak current for approximately 30% rolloff @ +25 C HCM1104-1R0-R to HCM1104-220-R 6. 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). 7.
