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.. 5. K-factor: Used to determine B p-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.
