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.
