COILCRAFT - Inductors, Transformers, Filters

DO1813HC Series High Current
Surface Mount Power Inductors

Our smallest high current inductor - only .24" x .35" x .197" high
Very high current ratings - up to 6 Arms; 7.7 A saturating current!
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 C131
