SMT Power Inductors - DO1605 Series
This series is designed for applica-
tions requiring high inductance, high
current and an ultra-low profile.
TheDO1605measuresamere1,8 mm
high and has a footprint of just 4,2 ×
5,4 mm. But despite this small size, it
isavailableinversionsthatwillhandle
up to 2.5 Amps. The series covers a
wide range of inductance values from 1 µH to 1.0 mH.
The flat top of the ceramic case provides the optimum
surface for reliable pick and place operations.
