Document 147 -1 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.
