Part number definition: HC7-XXX-R HC7 = Product code and size XXX = Inductance value in uH. R = Decimal point. If no R is present, then last character equals the number of zeros -R suffix indicates RoHS compliant 1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, @ +25°C 2. Irms: DC current for an approximately ΔT of 40°C without core loss. Derating is necessary for AC currents. Pad layout, trace thickness and width, airflow, and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 155°C under worst case conditions verified in the end application. 3. Peak current for approximately 15% rolloff @+20°C 4. Peak current for approximately 30% rolloff @+20°C 5. Applied Volt-Time product (V-μs) across the inductor. This value represents the applied V-μs at operating frequency necessary to generate additional core loss which contributes to the 40°C 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).
