Power Inductors – DC1012 Series
These power inductors are especially effective as DC-DC
converter boost or buck inductors and as output ripple filter
chokes in all types of switching power supplies.
They are ideal for applications through hole, cost effective
power inductors. The vertical style helps to save printed
circuit board area.The large inductance available per size
makes these parts ideal for all sorts of energy storage,
smoothing, and EMI reduction applications.
The Coilcraft DC1012 Series includes a wide range of
EIA standard inductance values. Custom versions may
also be available.
Coilcraft Designer’s Kit P410 contains three samples of
all the standard parts shown. To order, contact Coilcraft
or visit http://order.coilcraft.com.
