Open Circuit Inductance (OCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, @ +25°C 5. Applied Volt-Time product (V-μs) across the inductor. This value represents the applied V-μs at 2. Irms: DC current for an approximately ΔT of 40°C without core loss. Derating is necessary for operating frequency necessary to generate additional core loss which contributes to the 40°C 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-μs rating is equivalent to a ripple current I of 20% of Isat (30% rolloff option). p-p not exceed 155°C under worst case conditions verified in the end application. 6.
