DESCRIPTION
The 4300 series is a range of surface mount
dual-winding toroidal inductors designed for use
in switching power supplies and DC/DC converters.
These devices can also be used as common-mode
chokes, as the windings have a 1:1 ratio. They
are ideal for applications requiring low profile
compact components in a surface mount package.
