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.

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.
Weight: 2.1 – 3.0 g Terminations RoHS tin-silver (96.5/3.5) over tin over copper over steel Ambient temperature –40°C to +85°C with Irms current. +85°C to +125°C with derated current Storage temperature range Component: –40°C to +125°C Tray packaging: –40°C to +80°C Packaging 100 parts per tray
