DO3316HC Series High Current
Surface Mount Power Inductors

Very high current ratings - up to 16 Arms; 20 A saturating current!
Low profile and small footprint - only .51" x .37" x .25" high
Exceptionally low DC resistance thanks to the use of heavier gauge wire
Flat top and self-leaded design for reliable surface mounting
Robust temperature deflection prevents damage during solder reflow
Custom versions available
Samples of all values are available in Coilcraft Designer's Kit C126
