Open Circuit Inductance (OCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, +25C 6. Part number definition: HC8LP-XXX-R 2. Irms: DC current for an approximate DT of 40C without core loss. Derating is necessary for AC currents. HC8LP = Product code and size PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components XXX = Inductance value in uH. R = Decimal point. If no R is present then last character equals will affect the temperature rise. It is recommended that the temperature of the part not exceed 155C number of zeros under worst case operating 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 I is required to prevent excessive temperature rise. The 100% V-us rating is rms equivalent to a ripple current Ip-p of 20% of Isat (30% rolloff option).
