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.

Specifications typical at TA = 25°C
1 Maximum DC current occurs when either the inductance falls to 75% of its nominal value or when its temperature rise reaches 40°C,
whichever is sooner.
