Open Circuit Inductance Test Parameters: 100kHz, 0.25V, 0.0Adc. 2. Irms: DC current for an approximate ∆T 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 Amps peak for approximately 25% rolloff (@25°C). 2 www.eaton.com/elx 4. 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 μH), ∆I (Peak to peak ripple current in Amps). 5.
