DESCRIPTION
The ±900 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 laptop computers and plasma screens.

The maximum DC Current is the value at which the inductance falls to 65ꢀ (tolerance ±±0ꢀ) or 75ꢀ
(tolerance: ±20ꢀ) of its nominal 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 65ꢀ (tolerance:
±±0ꢀ) or 75ꢀ (tolerance: ±20ꢀ) of its nominal value.
