Open Circuit Inductance (OCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, +25C 6. Part number definition: HC9-xxx-R 2. Irms: DC current for an approximately T of 40C without core loss. Derating is necessary for HC9= Product code and size AC currents. Pad layout, trace thickness and width, airflow, and proximity of other heat generating xxx = Inductance in H. R = decimal point. If no R is present last character equals number of zeros. components will affect the temperature rise. It is recommended that the temperature of the part -R suffix = RoHS compliant not exceed 155C under worst case conditions verified in the end application. 3. Peak current for approximately 20% rolloff 20C 4. Peak current for approximately 30% rolloff 20C 5. Applied Volt-Time product (V-s) across the inductor. This value represents the applied V-s at operating frequency necessary to generate additional core loss which contributes to the 40C temperature rise. De-rating of the I is required to prevent excessive temperature rise. rms The 100% Vs rating is equivalent to a ripple current Ip-p of 20% of Isat (30% rolloff option).
