Open Circuit Inductance (OCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, +25C 5. Applied Volt-Time product (V-s) across the inductor. This value represents the applied V-s at 2. Irms: DC current for an approximately T of 40C without core loss. Derating is necessary for operating frequency necessary to generate additional core loss which contributes to the 40C AC currents. Pad layout, trace thickness and width, airflow, and proximity of other heat generating temperature rise. De-rating of the Irms is required to prevent excessive temperature rise. The 100% components will affect the temperature rise. It is recommended that the temperature of the part V-s rating is equivalent to a ripple current I of 20% of Isat (30% rolloff option). p-p not exceed 155C under worst case conditions verified in the end application. 6.
