DESCRIPTION
The 3700 series is a range of surface mount,
flat-coil wound power inductors. They are ideally
suited for use where high current and low loss
is essential, such as in laptop computers and
plasma screens.
PACKAGING INFORMATION

=25°C
1 The maximum DC Current is the value at which the inductance falls to 80% of its zero current value, or
when its temperature rise reaches 40°C, whichever is sooner.
2 Saturation current is the continuous current at 20°C ambient at which the inductance falls to 80% of
its zero current value.
