Selection and use
How to select
Choosing inductance
L ≈ (Vin − Vout) × Vout ÷ (Vin × fsw × ΔI), with ΔI at 20–40% of the output current. The series covers 1.0–33 µH in one body, so changing the value needs no new layout.
Saturation current Isat
the current at which inductance falls about 30%; keep the peak current below it.
Heating current Idc
the current that raises the part about 40 °C above a 25 °C ambient; ambient plus rise stays within 125 °C.
DC resistance
sets the conduction loss. Typical 1.65–39 mΩ across the series; use the maximum for loss budgets.
Rated voltage
75 V maximum; check it against the input voltage.
Height
Max 6.5 mm. Height-limited: VCMA-1350 (5.0 mm) on the same land pattern.
