Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.1 Vrms, 0.0 Adc, +25 C 2. 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. 3. Isat: Peak current for approximately 35% rolloff @ +25 C 2 www.eaton.com/elx 4. K-factor: K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * I. Bp-p: (mT), K: (K-factor from table), L: (Inductance in H), I (Peak to peak ripple current in Amps). 5.
