B p-p = K*L*∆I, B p-p: (Gauss), K: (K factor from table), L: (Inductance in uH), ∆(Peak to peak ripple current in Amps). (1) OCL: Open Circuit Inductance test parameters: 100 kHz, 0.1 Vrms, 0.0 Adc. (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 +105 °C under worst case operating conditions verified in the end application.
