Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.1 Vrms, 0.0 Adc. 2. Irms: DC current for an approximate ∆T of 40 °C without core loss. Derating is necessary for AC currents. PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 125 °C under worst case operating conditions verified in the end application 3. lsat: Peak current for approximately 30% rolloff @ 25 °C. 4. K-factor: Used to determine B p-p for core loss (see graph). B p-p = K*L*∆I, B p-p(mT), K: (K factor from table), L: (Inductance in uH), ∆I (Peak to peak ripple current in Amps). 5. Part Number Definition: SD53-xxx-R SD53 = Product code and size; -xxx = Inductance value in uH; R = decimal point; If no R is present then third character equals the number of zeros. -R suffix = RoHS compliant. 53 Dimensions (mm) Part Marking: Line 1: (1st digit= inductance value per Part Marking Designator); (2nd digit= Bi-weekly production date code); (3rd digit= Last digit of the year produced), (4th digit= Internal manufacturing code).
