Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.25 Vrms, 0.0 Adc. 4. DCR limits 20C. 2. Irms: DC current for an approximate T of 40 C without core loss. De-rating is necessary for AC currents. 5. Applied Volt-Time product (V-us) across the inductor at 100 kHz necessary to generate a core loss equal to 10% of Temperature rise is dependent upon several factors, including the PCB pad layout, trace thickness and width, air-flow the total losses for 40 C temperature rise. and proximity to other heat generating components. It is recommended the part temperature not exceed 125 C under 6. Part number definition: SD52-xxx-R worst case operating conditions and therefore, the temperature rise should be verified in the end use application. SD52= Product code and size 3.
