SL3732 Series
Notes:
1. Open Circuit Inductance (OCL) test condition: 100KHz , 1Vrms , 0Adc at 25℃.
2. L @ Isat and L @ Irms Test condition: 100KHz , 1Vrms (Ta=25℃).
3. The nominal DCR is measured from point "a" to point "b", as shown above on the mechanical drawing (Ta=25℃).
4. Isat1 , Isat2 : DC current that will cause inductance to drop approximately by 20%.
5. Irms: DC current for an approximate temperature rise of 40℃ without core loss.Derating is necessary for AC currents. PCB
pad layout, trace thickness and width , air-flow and proximity of other heat generating components will affect the temperature rise.
6. It is recommended the part temperature not exceed 130°C under worst case operating conditions as verified in the end application.
