Power Inductors – DC1012 Series

Document 147 -1

Document 147-1 Revised 07/31/12

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

1. When ordering, please specify

termination code:

DC1012-334L

Termination:

L = RoHS compliant tin-silver (96.5/3.5) over tin over

copper over steel.

Special order:

S = non-RoHS tin-lead (63/37).

2. Tested at 100 kHz, 0.1 Vrms, 0 Adc.

3. DC current at which inductance drops the specified amount from its

value without current.

4. Current that causes the specified temperature rise from 25°C ambient.

5. Electrical specifications at 25°C.
