SMD Power Inductors
ECM UC Series
This particular range of surface mount inductors, the UC series now comes in seven package sizes each with their own individual benefits. The range features some of the smallest footprint sizes available for product of its type, in addition the new UC1606 package is only 1.80mm high while offering safe current operation up to 2.5A (@ 1.0uH). While the UC5022 is available up to 1.0mH @ 1 Amp while maintaining a total height less than 8.0mm. Ferrite shielded versions of UC1608, UC3316, and UC5022 are also available.
