DESCRIPTION
The 3800 series is a range of surface mount, flat
coil wound power inductors that is designed for
use where high current and low loss is essential,
such as in laptop computers and plasma screens.

1 The maximum DC Current is the value at which the inductance falls to 65% (tolerance ±30%) or 75%
(tolerance: ±20%) of its zero current value or until its temperature rise reaches 40°C, whichever is sooner.
2 The saturation current is the continuous current at 20°C ambient at which the inductance falls to 65% (tolerance:
±30%) or 75% (tolerance: ±20%) of its zero current value.
