Electrical Characteristics of SL37408 Series:
3. Mechanical Dimension of SL37408 Series:
Notes:
1. Open Circuit Inductance (OCL) test condition: 100KHz,0.1Vrms,0Adc at 25Ԩ .
2. L @ Isat and L @ Irms Test condition: 100KHz,1.0Vrms (Ta=25Ԩ ).
3. The nominal DCR is measured from point "a" to point "b", as shown above on the mechanical drawing (Ta=25Ԩ ).
4. Isat1 , Isat2 & Isat3 : DC current that will cause inductance to drop approximately by 20%.
5. Irms: DC current for an approximate temperature rise of 40Ԩ 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.

1 Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.10Vrms, 0.0Adc

3 Irms: DC current for an approximate temperature rise of 40°C 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. It is recommended the part
temperature not exceed 125°C under worst case operating conditions verified in the end
application.
4 Isat1: Peak current for approximately 20% rolloff at +25°C.
5 Isat2: Peak current for approximately 20% rolloff at +125°C.
6 K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ΔI * 10-3, Bp-p : (Gauss),
K: (K-factor from table), L: (inductance in nH), ΔI (peak-to-peak ripple current in amps).
