Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.25 Vrms, 0.0A dc @ 25 C2. 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, airflow and proximity of other heat generating components will affect thetemperature rise. It is recommended that the temperature of the part not exceed 165 C under worst case operating conditions verified in the end application.3.
