DESCRIPTION

The 4900S series is a range of bobbin-wound,

surface-mount inductors designed for use in

switching power supply, and power line filter

circuits. The parts are suitable for any application

requiring a high saturation current in a low-profile

package. The devices have an integral ferrite

shield to reduce EMI.
