Additional Details

The VLS5020T series employs a ferrite core. The inductance value is 1.2µH with a specified tolerance. '1R2' in the part number signifies the inductance value. The rated current and DC resistance for the VLS5020T-1R2N variant can be found in the product datasheet. It is RoHS compliant.

Optimal performance relies on proper PCB layout. Keep traces short and wide to reduce parasitic inductance and resistance. A ground plane beneath the inductor will further minimize EMI.
