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.
