SMT Power Inductors – DO3340 Series
These surface mount power inductors provide excellent
current carrying capabilities in a small footprint compo-
nent — up to 3.5 Arms with an 8 Adc saturation current
rating for a 10 µH part.
These parts were engineered from the start for reliable
surface mounting. They have a flat top and robust
temperature deflection to prevent damage during solder
reflow.
In addition to the standard versions shown here, custom
inductors are available to meet your exact requirements.
