Power Inductors - DC1012 Series
Document 147
Document 147
Revised 10/31/08
These power inductors are especially effective as DC-
DC converter boost or buck inductors and as output
ripple filter chokes in all types of downsized switching
power supplies.
They are ideal for applications requiring small size, cost
effective power inductors. The vertical style helps re-
duce power supply size by saving crucial 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 are
also available.
Coilcraft Designer’s Kit P410 contains three samples of
all the standard parts shown. To order, contact Coilcraft
