OCL (Open Circuit Inductance) Test parameters: 300kHz, .25Vrms, 0.0Adc & Isat. 2. Irms Amps for approximately ΔT of 40°C. DC current for an approximate ΔT of 40°C without core loss. Derating is necessary for AC currents. 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 30% rolloff @ 20°C. 4. Applied Volt-Time product (V-μs) across the inductor. This value represents the applied V-μs at 200kHz necessary to generate a core loss equal to 10% of the total losses for 40°C temperature rise. See Core Loss Graph. 5.
