Open Circuit Inductance (OCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, +25C 6. Part number definition: HC7-XXX-R 2. Irms: DC current for an approximately T of 40C without core loss. Derating is necessary for AC HC7 = Product code and size currents. Pad layout, trace thickness and width, airflow, and proximity of other heat generating XXX = Inductance value in uH. R = Decimal point. If no R is present, then last character equals the components will affect the temperature rise. It is recommended that the temperature of the part not number of zeros exceed 155C under worst case conditions verified in the end application. -R suffix indicates RoHS compliant 3. Peak current for approximately 15% 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 Irms is required to prevent excessive temperature rise. The 100% V-us rating is equivalent to a ripple current Ip-p of 20% of Isat (30% rolloff option).
