Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.1 Vrms, 0.0 Adc. 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), 2. Irms: DC current for an approximate T of 40 C without core loss. Derating is necessary for AC currents. PCB layout, L: (Inductance in uH), I (Peak to peak ripple current in Amps). trace thickness and width, air-flow, and proximity of other heat generating components will affect the temperature 5. Part Number Definition: SD53-xxx-R rise. It is recommended that the temperature of the part not exceed 125 C under worst case operating conditions SD53 = Product code and size -xxx = Inductance value in uH R = decimal point verified in the end application If no R is present then third character equals the number of zeros. 3. lsat: Peak current for approximately 30% rolloff 25 C. -R suffix = RoHS compliant. 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).
