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.
