Document 186-1 SMT Power Inductors - DS1608 Series These shielded, ultraminiature inductors can help achieve significantly longer battery life in handheld communication devices and other portable products. They offer the highest efficiency, smallest size and lowest cost of any comparable part. DCR is 10 to 60% lower than other inductors, with greatest improvements seen at values from 100 to 10,000 µH. Their flat top and heat resistant materials ensure trouble-free assembly and reflow operations. Coilcraft Designer’s Kit C115 contains samples of each of the standard parts shown.
