PRODUCT OVERVIEW
The 4000 series is a range of surface mount
toroidal inductors designed for use in switching
power supplies and DC/DC converters. The parts
are ideal for applications requiring low profile
compact components in a surface mount package.

=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.
