yageo corporation smd inductor / beads sds0402bl series shielded smd power inductors these shielded ultra-miniature inductors can help designers achieving signifcantly longer battery life in handheld communication devices and other portable products. the sds0402bl series offers the highest effciency, smallest size and lowest cost of any comparable part. dc resistance is 10% to 60% lower than other inductors, with greatest effciency improvements seen at inductance values from 100 to 10,000h. these magnetically shielded inductors are designed with a fat top and constructed of heat resis - tant materials to ensure trouble-free assembly and refow operations. electrical characteristics p art ind uc ta n ce to lera n ce d c in sulati on sr f c urre n t no .
